Leds of graphic visualisation of thresholds5. On/Off key6. Sensitivity/Manual autozero key DF 110Perform a measurement• Turn on the detector pressing the “On/Off” key.When it turns on, the pre-heating phase of the sensor begins. This phase lasts 60 seconds. During this phase, all the visualisation leds of thresholds light one after the other. A few second before the end of the pre-heating phase, all the leds blinks at the same time.Before using the device, make sure with the tester that the device works correctly (see next page).• Place the probe as close as possible to the site of the suspected leak.• Slowly move the probe (approximately 2 cm/second) in the direction to the possible source of the leak.It is important to move the probe past the leak and to go back toward it. The device responds to changes in gas concentration in the air. Moving the probe allows to the device to respond properly to these changes. If gas is detected, the frequency of the beep repetition will increase as the detected gas concentration increases and the leds of graphic visualisation lights from the left (low gas concentration) to the right (high gas concentration).Manual and automatic autozero functioningThe detector performs an automatic autozero every 2 s to set its minimum threshold of detection. This autozero allows to guarantee an optimum gas detection whatever the conditions of use (contaminated environment, temperature variations,...). In case of detection, according to the amplitude of gas measurement, the automatic autozero will deactivate to guarantee a better location of the leak. It will automatically reactivate after a return to normal conditions. In case of high gas concentration with a wide contaminated area, the automatic autozero can be not enough to detect precisely the location of the leak, there will be a measurement saturation. In this case, it is possible to perform a manual autozero into the contaminated area to reset the detection and to get back to a progressive sensitivity when getting close to the leak source.To perform a manual autozero, please see next page.Setting of the sensitivityIf the gas concentration is high, press “Sens” key to set the sensitivity and like this to get a better identification of the leak source. Please see next page for the details about the three different sensitivities.Adjust the deviceAdjust the sensitivity•Press the “Sensitivity/Autozero” key to adjust the sensitivity of the device.Activate/deactivate the audible signalBy default, when starting the device, the audible signal is always active.The device is turned on.• Press key to activate the audible signal.• Press this same key to deactivate it.Perform an autozeroThe device is turned on.• Press at least 3 s the key to perform an autozero.The “Autozero” led turns on.Perform a testThe DF 110 is supplied with a tester which allows to make sure that the detector works correctly.To test:• Remove the tester cap by pulling on it.• Turn on the detector and wait the end of the pre-heating phase (60 seconds).• Put the detection probe a few centimetres above the tester. The beep frequency increases and the leds of graphic visualisation must react and lights from the left to the right. This indicates that the sensor and theelectronic of the detector work correctly.After each test, remember to put the protective cap back on the tester.Replace the tester when its green colour is no longer visible.• Unscrew the probe tip.• Remove the filter located inside.• Put a new filter.• Screw the tip on the probe.Change the filter• Remove the front part at the back of the device.• Change the old batteries by AAA LR03 1.5V batteries.• Replace the front part.Change the batteriesN T _E N – D F 110 – 07/10/22 – N o n -c o n t r a c t u a l d o c u m e n t – W e r e s e r v e t h e r i g h t t o m o d i f y t h e c h a r a c t e r i s t i c s o f o u r p r o d u c t s w i t h o u t p r i o r n o t i c e .。

Sparks or hot surfaces can ignite hydrogen gas.The SBS-H2 hydrogen detector acts as a monitor and provides a visual and audible alarm when hydrogen is detected. The unit also has a 1% concentration relay that can trigger exhaust fan operation and a 2% concentration relay that can trigger a building management/alarm system (via SCADA/Modbus) before the gas reaches the lower explosive limit (LEL) of 4.1%.2.0 BenefitsIn addition to protecting employees and property, the detector may also reduce the following costs: Energy EfficienciesInstead of continuously running an exhaust fan to prevent hydrogen gas accumulation, use the detector to activate a fan only if the gas concentration reaches 1%.Insurance SavingsInstallation of a detector in areas where batteries are charged may result in a premium reduction.3.0 How it WorksShould the concentration of hydrogen gas in the air surrounding the sensor reach 1% by volume, the “1% Warning” yellow LED will light up on the main control of the unit. In addition, the 1% internal relay will energize and can be used to activate a remote exhaust fan.Should the hydrogen gas concentration reach 2% by volume, the “2% Alarm” red LED will light up, the strobe will flash and an audible alarm will sound. In addition, the 2% internal relay will energize and can be used to activate a building management/alarm system (via SCADA/Modbus).The SBS-H2 provides automatic operation, continuous detection, high sensitivity, stability and solid-state reliability.

Conductivity of the sensor is proportional to the gas concentration, which is continuously monitored by the electronic alarm circuits.The sensor only monitors for hydrogen gas (H 2) and will not alarm for Hydrogen Sulfide (H 2S), which has an odor at very low concentrations.6.0 Main ControlSensor HeadStrobe AlarmIndividual Sensor Indicators(For troubleshooting, refer to page 14.)Hydrogen SensorCat5 Cable(25 ft. std., 50/100 ft. optional)Main ControlMain Control Indicators (3 LEDs)7.0 InstallationWARNINGAC voltage relay terminals (120/240 Vac) are located within this detector, presenting a hazard toservice technicians. Only qualified technicians should open the detector case and service the internal circuits. Ensure power is removed from the detector relays prior to servicing the unit. Failure to do so may result in injury or death.Mounting and Power OptionsAlarm WiringH2-JB Junction Box Mountable (optional) Mounts to a standard, 4 11/16" x 4 11/16" 2-gang junction boxHardwire OptionRun AC and/or DC power and alarm wires through back of the unit, into the gang box and out through conduit.E190399 AC Line Cord3-prong grounded AC cord, 18-3 AWGWall MountableIntegrated back mounting plate allows user to easily mount directly to any wall using 3/16" screws (not included).WiringPower and alarm wires can run through the sides of the unit.Input PowerMounting LocationHydrogen is colorless and odorless; the lightest of all gases, and thus rises. The sensor should be installed at the highest, draft-free location in the battery room, cabinet or compartment where hydrogen gas would accumulate.The detector measures hydrogen gas concentration in the air immediately surrounding the sensor. The area one sensor will monitor depends on the properties of the battery compartment or room. Hydrogen gas may accumulate in several areas of the battery compartment or room and multiple sensors/detectors may be necessary.The main control can be mounted wherever is convenient for the user, but should be within the cable length range to connect to each sensor.The sensor should be mounted at the highest, draft-free location in the battery room, cabinet or compartment. Each sensor connects with the main control via the cable.Carefully remove the main control cover by removing the two screws located on the front of the cover. Attach the main control to the wall, ceiling or optional junction box using the mounting holes at the top and bottom of the main control’s mounting plate.After the power and relay wiring is complete, connect each cable from main control to each sensor and refasten the main control cover.Power OptionsThe detector has terminal blocks for connections to a single-phase 120/240 Vac 50/60 Hz power source (Terminal J8), and/or a 12-48 Vdc power source (Terminal J9). The power supply inputs are redundant, so the unit can use the DC input as a backup source.RelaysThe detector has two (2) internal alarm relays:∙1% warning relay (Terminal J6) is activated when a sensor detects 1% concentration of hydrogen gas. The 1% relay’s dry contacts are rated at 10A/250 Vac, sufficient for most 1/3HP exhaust fans.∙2% alarm relay (Terminal J3) is activated when a sensor detects 2% concentration of hydrogen gas. The 2% relay’s dry contacts are rated for 0.5A/28 Vdc.∙Note: For higher current requirements, add an external relay.Mounting OptionsJunction Box MountedFor 120/240 Vac power, use 18-3 gauge stranded wire.For 9 - 58 Vdc power, use 18-2 conductor insulated wire.For relay wires, use stranded wire. Maximum wire size for connector terminations is 14 AWG. Stranded conductors must be terminated in a manner to prevent shorting from one terminal to another by a loose strand. Tin the wires with solder if required.Wall MountedFor 120 Vac power, an 18-3 gauge insulated line cord is required.For 9 - 58 Vdc power, use 18-2 conductor insulated cable from the DC supply.For relay wires, use stranded wire. Maximum wire size for connector terminations is 14 AWG.Disconnection of Supplying PowerWhen the unit is hard wired, an external 10 Amp (minimum) circuit-breaker or switch should be installed to act as a disconnecting device. The circuit-breaker must open all supply conductors simultaneously, be easily reached by operators and be marked as the disconnecting device for the equipment.For Installation of Additional SensorsA maximum of three (3) sensors may be connected to each main control. Multiple detectors and sensors can be installed to meet the space coverage requirements of your particular installation.Locate the additional sensors ’ installation points within cable reach of the main control and mount the sensor. Connect the cables from any additional sensors to the Sensor 2 and Sensor 3 inputs on the main control.SBS supplies a tie-wrap to secure the AC mains ’ wiring. The tie wrap can rotate up to 270 degrees to accommodate your installation.Alarm System ElectronicsPlease refer to the illustration below to identify proper power and relay connection points in the detector. It is advisable to use a pair of 14 gauge or smaller stranded wire for the relay contacts to help reduce any interference within the area that may cause false alarms.Each of the Cat5 sensor input connections has a status indicator LED on the main control, which will illuminate solid green when a sensor is connected and operating normally. A sensor’s corresponding LED will flash at the same rate as the strobe LED when detecting 1% or 2% H2 concentration. The LED for a sensor that is in alarm mode will flash at the same rate as the strobe LED. The alarming sensor and strobe LED will flash at a faster rate than the LED for a sensor that is only in warning mode.Terminal Connection DiagramUsing the Mechanical Relays1. Remove the front cover of the main control by removing two fix screws and pulling straight offthe body. This will reveal the inner electronics of the alarm box.2. Locate the terminal blocks for the relays and determine which condition you would like therelay to be related to. Use the 1% relay (Terminal J6) for the warning condition and the 2% relay (Terminal J3) for the alarm condition.3. Replace the front cover on the alarm box.8.0 OperationKeep the detector on at all times. The solid green LED for ‘POWER’ on the main control indicates that the detector is powered on.When power is first turned on, a warm up period of 30 seconds will elapse before the unit will function. This delay is to prevent false activation of the internal relays and alarm.Should the concentration of hydrogen gas in the air surrounding the sensor reach 1% by volume, the “1% Warning ” yellow LED will light up on the main control of the unit. In addition, the 1% internal relay will energize and can be used to activate a remote exhaust fan.Should the hydrogen gas concentration reach 2% by volume, the “2% Alarm ” red LED will light up, the strobe will flash and an audible alarm will sound. In addition, the 2% internal relay will energize and can be used to activate a building management/alarm system (via SCADA/Modbus).Power Warning Alarm(sensor installed)(blinking green))(same flash rate as strobe)Warning and Alarm Relay Sensor/Cable Fault(plugged in, but not lit)Main Control IndicatorsIndividual Sensor Indicators9.0 Electrical TestingA "TEST" button is located on the front of the main control. Push and hold this button for approximately 10 seconds to test the unit's electronic circuitry.The warning and alarm LEDs will light up in sequence, the strobe will flash, the relays will activate whatever is connected to them and the internal warning alarm will sound.Note: The "TEST" button does NOT test the sensor(s) itself –only the unit’s electronic circuitry.10.0 Testing the SensorThe sensors and main controls are factory calibrated. It is recommended to test each sensor’s functionality every 12-18 months with the H2-TESTKIT.The H2-TESTKIT is intended for periodic testing of the functionality and proper operation of the system. Once a sensor is installed, calibration or adjustment of the sensor is not possible. Please contact your sales representative if sensor calibration is desired or required.The H2-TESTKIT includes the following:∙1% (17 liters) H₂ in air calibrated gas canister∙2% (17 liters) H₂ in air calibrated gas canister∙Regulator∙Flexible tubing with sensor head adapterTesting the 1% Warning and 2% Alarm State1. Connect the calibration fixture to the 1% H2 air gas cylinder.2. Secure the test fixture to the sensor module connected to sensor by pressing the flexible tubingcompletely over the inlet to the sensor head.3. Turn on the gas flow by slowly cracking the valve on the cylinder regulator until gas begins toflow. Please wait 30 seconds to ensure the air in the tubing has been purged.4. Continue gas flow and wait for the yellow LED warning to light up and the 1% relay to energize.5. Turn off gas and remove from sensor.6. Repeat Steps 1-5 above using the 2% H2 air gas cylinder to activate the 2% alarm and relay.The 2% alarm threshold is connected to the red LED, the audible alarm and the strobe light up, which will activate during testing.7. Repeat steps for every sensor installed.Note: If the unit does not alarm during these tests the sensor may need to be replaced.Replacing the SensorIn a typical operating environment SBS recommends that each sensor be replaced every three years. An abusive operating environment can and will shorten a unit’s useful life. In dusty/dirty applicationsor in situations where a sensor is often subjected to different gases, it is recommended to replace each sensor after one (1) year.11.0 Troubleshooting and MaintenanceNo PowerVerify the AC and/or DC power cables are installed per the connection diagram on page 11.RelaysThe SBS-H2 system was designed for the relays to operate in a failsafe condition when the power supply is interrupted. If the fan connected to a relay runs as soon as the unit is powered on, the unit has been wired for the use of the Normally Open contact instead of a Normally Closed contact.False AlarmsEach sensor has been calibrated for the detection of hydrogen gas, however any combustible gas that comes in contact with a sensor has the potential to activate the warning and/or alarm relays. Contact with any individual or combination of the following gases could trigger false alarms and/or contaminate a sensor.Gases include but are not limited to:-Acetone-Acetylene-Ammonia-Benzene-Butane-n-Butyl Acetate -Carbon Dioxide -Carbon Monoxide -Ethane-Ethanol-Ethyl Acetate -Ethyl Ether-Ethyl Oxide-Gasoline-Heptane-Hexane-Hydrogen-Hydrogen Cyanide-Hydrogen Sulfide-Isopropyl Alcohol-Methane-Methanol-Methyl Ethyl Ketone-Nitric Oxide-Nitric Dioxide-Propane-Propylene Oxide-Styrene-Sulfur Dioxide-Toluene-Turpentine-Vinyl Acetate-XyleneIf a sensor’s warning or alarm condition is reached, ventilate the area with clean air. This should reduce the concentration of most gases and the warning or alarm condition should clear.Note - when a warning occurs at 1%, the warning will not clear until concentrations drop below 0.5%. Similarly, when an alarm occurs at 2%, the alarm will not clear until concentrations drop below 1.5%.Avoid installation in highly corrosive environments where high densities of hydrogen sulfide, sulfur oxide, chlorine, hydrogen chloride, etc. may be present. These gases can cause corrosion of the element and the power leads to the circuit board.A sensor’s output characteristics can be affected if the sensor becomes contaminated or exposed to heavy alkaline metals.A sensor cannot operate in a zero or low oxygen content atmosphere.If a sensor collects water condensation, its characteristics may temporarily drift. However, light levels of condensation under normal indoor use should not pose a significant problem with performance. StorageThe longer a sensor is stored prior to being energized, the longer the warm up and stabilization period may become. Storage Humidity Range: 5 - 95% non-condensing.Maintenance TipsTo maintain the unit, it is recommended to:1. Test the detector once a month by pressing the ‘TEST’ button.2. Vacuum the alarm cover once a month to remove accumulated dust.3. Never use detergents or solvents to clean the unit or sensor. Chemicals can permanentlydamage or temporarily contaminate a sensor.4. Avoid spraying air fresheners, hair spray, paint or other aerosols near a sensor.5. Never paint the unit or sensor. Paint will seal the vents and interfere with proper sensoroperation.WARNINGSDo not disassemble unit or attempt to repair or modify any component of this instrument. This instrument contains no user serviceable parts, and substitution of components may impair intrinsic safety, which may adversely affect product performance and result in injuryThe SBS-H2 Hydrogen Alarm System is not a standalone safety device and does not provide protection from hydrogen explosions. The relay contacts are intended to be connected to a safety system, enabling audible alarms, system shutdown, ventilation, or other measures to ensure monitoring of hydrogen gas occurs before concentrations reach dangerous levels.The information in this sheet has been carefully reviewed and is believed to be accurate; however, no responsibility is assumed for inaccuracies.
