The JA-60G Wireless Gas Leak Detector 2 / 2 MEF51311
The JA-60G Wireless Gas Leak Detector
The JA-60G detects mixtures of air and combustible gases or fumes
(Natural Gas, Methane, Propane, Butane).
The mains-powered detector indicates a gas leakage optically, and
acoustically, and transmits alarm signals wirelessly via radio protocol of
Jablotron 6x systems.
Installation
Installation shall only be undertaken by technicians holding a certificate
issued by an authorized distributor. Warning: this device is connected
to the mains.
Fix the detector on the wall. For gases lighter than air (natural gas, city
gas etc.) install it close to the ceiling (max. 15 cm under it) or directly on
the ceiling and on the place expected to have gas leakage. For gases
heavier than air (propane, butane, etc.) install it close to the floor or on
the lowest place of the room. The detector should not be located close
to any obstacles preventing natural air circulation.
The detector should not be located close to any obstacles preventing
natural air circulation. It should also not be located in a draft or close to
a cooker (cooking smells and other fumes can have a bad influence on
gas detection)
Connect the wires, set the detector’s features using its DIP switches
and close its cover.
Before you connect power, switch the control panel (receiver) to
enrollment mode. The detector transmits enrollment signals when its
power is connected.

Power terminals
Route the power cable to the terminals marked 230V AC. The power inlet
should be fused with an external fuse (max. 10A). Do not open the detector
cover if the power is on.
Output relay terminals
There is a dry relay switch-over contact available (max. 5A/230V AC)
C - common contact
NO- normally open contact
NC- normally closed contact
This relay output could be used for example to shut down the gas inlet if
there was a gas leak (by means of a suitable electric gas valve).
Warning: The mains relay output does not provide mains isolation for safety!
DIP switches
There are two DIP switches in the detector to set its features:

indication of gas leakage will last

off (memory function)
Function
After switching the power on, the detector transmits its enrollment signal
and the green LED flashes for about 90 seconds while the detector warms
up. When the green LED lights constantly, the detector is ready for operation.
If the gas concentration reaches the 1
st
level, short beeps sound and the
first red LED lights.
If the gas concentration reaches the 2
nd
level, long beeps sound and the
second red LED lights.
The output relay reacts depending on DIP switch #1’s setting.
A fire alarm signal is transmitted wirelessly at the same moment as the
detector’s relay reacts (depends on DIP switch #1’s setting).
The JA-60G detector does not regularly check communication with the
control panel (receiver), so the system will not indicate a lost detector during
power dropouts.
Warning - If there is a gas alarm, don’t operate any switches or
electrical devices. Open the windows, and stop the gas leak, if
practical. Call the fire department immediately, but do not use a phone
inside.

Maintenance and testing
Keep the detector clean, it is important that its grids should not be blocked
with dust.
Use a gas cigarette lighter without the flame lit, to test the gas detector’s
reaction. The detector will react within 15 seconds.
Professional recalibration of the detector should be done at least every 1
year. Contact your distributor for more details.
