TECHNICAL MANUAL

This device can detect the presence of an abnormal concentration of LPG or natural gas in quantities
much lower than generally accepted as the danger threshold. It raises optical (LED) as well as acoustic
(buzzer) alarms on detecting a gas leak. At the same time, it can be equipped to operate a solenoid
valve to cut off the gas supply. It can also be connected to an external Remote Siren/Buzzer.
Technical Specification
• Supply voltage: 230 V~ 50-60 Hz
• Power consumption: Static < 1W
Alarm < 3W
• Sensor: Tin dioxide semiconductor
• Inducing gas - coal gas / natural gas and liquified petroleum gas (LPG)
• Alarm density - 1000 ppm to 5000 ppm
• Alarm operating threshold:
- 10% LEL (Lower Explosive Level)
• Terminals 1-2-3: output relay with change-over contact for connecting extra alarm signals
(terminals 3-1) or a solenoid valve (terminals 3-2)
• Operating signals:
- acoustic through piezoelectric (buzzer) 85 dB at 1 m
- optical, through frontal LEDs (green, yellow, red)
• Protection degree: IP40
• Operating temperature: 0 °C - +40 °C
• Allowed relative humidity: max 80%
• Fire retardant poly-carbonate enclosure
Special Features:
The gas detector can be installed stand-alone to raise an alarm in the event of leakage of combustible
gas. An additional remote alarm & shut OFF valve can also be connected.
b) Alarm Situation: Upon detecting the presence of gas above the alarm threshold, the Red LED will start flashing and the buzzer will sound.
c) Faulty Display: When the Yellow LED flashes along with buzzer, it indicates that the sensor is faulty.
Operation :
a) Warm-up Situation: When the gas alarm is switched ON, the green LED light will flash, indicating the warm up period. The LED will stop flashing
after approximately 3-5 minutes. The green LED will then remain illuminated indicating that the gas alarm is functional.
Installation location:
The gas leakage alarm is to be located as per the specific gravity of the gas in use.
a) Natural gas or coal gas: Natural gas is lighter than air. In this case the gas detector should be installed near the ceiling. It is advised to locate
the alarm 30cm below the ceiling at a distance of about 1.5m away from gas appliances (fig. 1)
b) Liquid Petroleum Gas (LPG): Its specific gravity is heavier than air, so it sinks to the bottom. As such, it is advised to install the alarm 30cm
above the floor at a distance of about 1-1.5 meters away from the gas appliance (fig. 2).
c) Should not be installed near doors, windows or exhaust fans.

1. The detector can be installed stand-alone and if desired, along with network function for remote
warning
a) Standalone function: Install the unit at a suitable position with wiring as shown in figure 1 (for
natural gas) and figure 2 (for LPG).
b) Network function: Connect the passive (potential free) NO contact of the detector to remotely
located warning device together with the powe supply. (fig. 4)r
2. You can also connect the gas detector to a solenoid valve (installed on the gas supply line) to cut off gas supply to the stove on detection of
a leakage. The solenoid valve gets activated the moment it receives a signal from the gas detector (fig 4).

Distress Warning
• In case of leakage of combustible gas, the red LED will flash along with warning buzzer. Appropriate warning at remote location will also be
raised through network, if connected.
• When the gas density falls lower than alarm initializations, the alarm will stop sounding.
• When required, the alarm can be reset manually by test/reset button.
Action in Alarm Situation
When the gas density is up to standard alarm density or higher, the siren will sound continuously.
In such a situation:
• Close the valve of the gas feeding line immediately.
• Open windows immediately to ensure ventilation.
• Extinguish all fire sources and avoid using lighters, matches, etc.
• Avoid switching electrical appliances ON or OFF.
• Check reasons for the gas leak and notify concerned department or professionals in time.
• If the alarm continues to sound in spite of closing the leak, user should check the location of the detector.
Caution
• Avoid mounting the detector close to a gas stove, in the vicinity of flames, oil vapors, exhaust fan, windows and bathroom as it can affect
the sensitivity of the detector.
• Must maintain the product as per instructions.
• Users should test the gas detector every 6 months. If it is defective, users should have it attended or replaced quickly.

Gas cut off
valve

The AFO1B series are emergency automatic shut-off solenoid valves for gas line. They are safety apparatus used in gas pipeline cut-off at an
emergency. The valve can be connected to the alarm systems for gas leaking or the control terminator modules of fire alarm or other intelligent
alarm systems to cut off the gas source automatically or manually either in field or in distance so as to assure safety of gas users. The valve will be
closed automatically in the case of shaking violently. The reopen of the valve requires a manual action. These features meet the regulations and
requirements in safety control and accident handling.
Principle of Operation
The valve utilizes the interactions between momentary solenoid force and permanent magnetic force and spring force to maintain the valve closing
with the pulse and the valve opening with hands.
Principle of the valve closing
The valve is closed with momentary direct current pulse (9-12VDC/1S).
Scheme for capacitor discharge drive circuit
• There are two ways to close the valve. (a) The valve will be closed quickly when a momentary (about 1 second) direct current pulse (9~12VDC)
is given to the solenoid coil. (b) The red handle is pushed down with a hand after the protection cover opening. The closing status will be kept by
the valve itself.
• NOTE - Do not open the protection cover in normal situation so as not to close the valve by mistakes.
• There is only one way to open the valve when it is in closing status. The way for opening is to pull the red handle up with a hand. The opening
status will be kept by the valve itself.
• NOTE - If there are difficulties to pull the red handle up with a hand, special steps should be taken to balance the pressure at the outlet and inlet
of the valve and then try opening again.
• The opening status The valve will be closed automatically due to the magnetic lock design when harmful shaking violently occurs. If the self-
locking function of the valve is not normal or partially lost, please inform the manufacturer to have a check on it.
• The valve closing status should be confirmed by users in field. The valve reset and gas supply restart can be done only when the source of gas
leaking has been find out and the problem has been solved.

Operations
Light Settings
The Passive Infrared Detector and Smart Passive Infrared Detector both have settings for light detection and time delays. The light detection option
allows you to decide the light intensity at which the associated device should be switched ON. If you move the Light Setting dial to its maximum
position in a clock-wise manner, the device will get activated only when it detects movement when there is daylight. It will also switch on during
Twilight and Dark conditions. If you keep the Light Setting dial at the center, the device will get activated only when it detects the presence of a
person during Twilight or total Darkness. If you move the dial to its maximum position in an Anti-clockwise direction, the presence detector will
activate the device only if it detects a person in total darkness.
Time Delay Settings
The Time Delay dial allows you to select the period till which the device will remain active after the person leaves the area of detection or after the
device notices lack of activity. The minimum time is 8 to 10 seconds and the maximum time is 5 minutes. For example, if you select maximum time
of 5 minutes, the device associated with the Infrared Detector will remain active for 5 minutes after the person has moved away from the area of
detection. To decrease the time delay, move the dial in the anti-clockwise direction. To increase time delay, move the dial in anti-clockwise direction.
Auto, ON & OFF
The (2M) has an additional switch that has three options: On, Off and Auto. The Auto mode is the default mode in which it detects theSmart PIR
presence of a person and activates the device associated with the detector. In the ON and OFF mode, the detector acts as a simple switch that
activates or deactivates the device associated with it.
Note: 1) For LED loads, use SMPS based power supply with power factor 0.80 or above.
2) Do not connect loads having individual power supply.
