Addressable Natural Gas Detector
Type :71CNG
TECHNICAL SPECIFICATION
ENGLISH
GENERAL DESCRIPTION
The 71CNG detector (fig.1) is applicable for detection of natural gas (methane) in the protected area. The status of the detector is
indicated with LEDs and sounder.
The 71CNG detector has a signal (communication) and external power interface lines.
The signal loop (communication) interface line is compatible with the IFS7002 fire control panel through the UniTalk private protocol.
The signal loop (communication) interface power supplies the communication, micro-controller, detection schematics of the device.
In order to be fully functional, the 71CNG device requires additional external power supply in the range (18 – 30) Vdc, which supplies
the sounder and Led indication and heating of the sensor.
The signal loop (communication) interface is protected with a short-circuit isolator.
Both power supplies are galvanic-separated and must not be with common ground. The common ground will not damage the
standalone operation of the 71CNG, but will affect the communication between the detector and the IFS7002 control panel.

ATTENTION !!! OPERATION TO BE DONE IN CASE OF ALARM:
– Put out any flames.
– Close the gas tap or the cylinder.
– Do not turn any electrical consumers on or off.
– Open all windows and doors to increase ventilation.
– If alarm stops it is necessary to discover the cause and act on consequence.
– If the alarm continues and the cause is not evident or possible to eliminate leave the room
immediately and call the emergency service.

CONTROL AND INDICATIONS
The 71CNG detector's functions are indicated through the following LEDs (fig1 pos.1):
green -
indicates working power supply status of the detector
- If the green LED is continuous On - there is properly working power supply
yellow –
indicates fault and service status.
- If the yellow LED is blinking - the gas sensor is in heating (warm-up) procedure for 120 seconds
- If the yellow LED is continuous On - there is fault in the 71CNG detector
red
and
yellow
– indicates duty and verification mode
- If both LEDs are continuous On - a service command is required in the IFS7002 control panel (Menu setup>Initializa-
tion>Check)
- If both LEDs are blinking simultaneously in a period of 16 sec. - there is fault in the 71CNG detector
red –
indicates alarm
- If the red LED is continuous On - the methane level is over the calibrated trigger level in the device
and
