General Description

SensoIRIS GAS is a gas detector designed for application in addressable fire alarm
systems, supporting TTE communication protocol.
SensoIRIS GAS is designed for detection of leaking natural gas and LPG. The
detector is equipped with alarm output for management of manipulator
electromagnetic valve (optional accessories).
SensoIRIS GAS is suitable for wall mounting using metal hanger included in the
supplied equipment.
The detector is full programmed from the fire alarm panel - see for details the
programming manuals of IRIS and SIMPO addressable fire alarm panels.
Kit includes:
Gas detector - 1 pc; Hanger - 1 pc; Manual - 1 pc.

Choosing the Installation Place

Attention: Check if the induced gas is heavier or lighter than air - this is
important when choosing the right place for installation.
Important Note: Avoid installation of the detector close to sources of direct air flow:
vents, fans, air-conditioners, doors, windows, sources of steam, oil vapor, etc.

Test and Maintenance

Test. To start the test procedure press the test button for more than 3 sec. Apply gas
at distance of 5 cm to the gas convection holes at the bottom of the detector. The red
status LED will start blinking. The detector will resume to normal operation while the
gas density is reduced to level lower than the alarm level.
Note: The frequently testing may result in reducing the sensitivity of the detector.
Maintenance. Clean the gas convection holes every 3 month and test the operation
of the detector.

and under the terminal cover.
- The LPG is heavier than
air and the detector should
be placed at height from
the room floor between 0.3
- 1.0m.
- The Natural Gas is lighter
than air and the detector
should be placed at height
from the room ceiling 6

Press for more than 3 sec to start a test.
Press for 1-2 sec to open the valve (if connected).
Power LED (green)
Blinking for 3 minutes during the initial power up.
Lights on permanently - the detector is in normal operation mode.
Status LED (red/ yellow)
Blinking into red - gas leaking alarm. The internal buzzer is on.
The valve (if connected) will close to shut off the gas pipeline.
Lights on in yellow - detector failure. The internal buzzer is on
with long beeps.
