1.9.5 Sequence of a gas alarm
If an assigned wireless gas alarm sends out an alarm signal because
a critical gas concentration has been reached, this will signal an alarm
whether the system is armed or not.
The siren sounds for about 30 seconds with short interruptions.
The status LEDs flash for about 180 seconds
.
If the cause of the alarm is not eliminated (critical gas concentration),
the LEDs will start to flash again until the gas concentration has reached
a non-critical level.
1.9.6 Interrupting an alarm with the handheld transmitter
Any button interrupts the alarm or disarms the system.
The LEDs flash twice and the internal buzzer gives out
a long signal (approx. 4 seconds).
1.9.7 Using the wireless gas alarm (accessory)
The wireless gas alarm can be switched on or off via the pressure switch
on the narrow side of the casing. After switching on, the power lamp on
the front lights up green. After the cleaning phase has finished, which
lasts approx. 4 minutes, the system flashes green and the gas alarm now
monitors the room air for critical concentrations of propane, butane and
narcotic gases.
Spray cans (hairspray and deodorants etc.) contain combustible propellants
which can trigger the gas alarm at high concentrations. Even strong
cleaning agents can trigger the gas alarm at high dosages because of the
aerosols they contain. We therefore recommend deactivating the gas alarm
when using these materials.
1.9.8 Using the cable loop (accessory)
The cable loop can be plugged into the holder when the system is either
armed or disarmed. It can be used to secure bicycles, motor scooters,
camping furniture, surfboards and many other movable objects. Once the
cable loop has been placed in the holder and the system has been armed,
cutting the cable or removing it from its holder will trigger the alarm.
