The JA-80G Wireless Gas Leak Detector 2 / 2 MKN51004

The JA-80G Wireless Gas Leak Detector

The JA-80G is a component of Jablotron’s Oasis 80 alarm system and detects

mixtures of air and combustible gases or fumes (Natural Gas, Methane, Propane,

Butane). The detector detects two levels of gas concentration, responding with two

different reactions.

The mains-powered detector indicates a gas leakage optically, and acoustically,

and transmits alarm wirelessly via Oasis protocol.

Installation

Installation shall only be undertaken by technicians holding a certificate issued

by an authorized distributor. Warning: this device is connected to the mains.

Installation should be done according to EN 50 244 by a person with a appropriate

qualifications!

 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:

No. OFF ON

1 relay is triggered if the 1st level

of gas concentration is

exceeded

relay is triggered if the 2nd level

of gas concentration is exceeded

2 indication of gas leakage will

stop after the concentration

drops down

indication of gas leakage will last

until the detector power is

switched 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 1st level, short beeps sound and the first red

LED lights.

If the gas concentration reaches the 2nd 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-80G 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.
