EXXFIRE Installation and Service Manual 96
Reset Alarm/Gas Released
When an EXXFIRE® 750CNF/1500CNF/2250CNF system shows the Alarm condition it will remain
doing so even when the smoke level drops to normal values or when the MAB has been reset.
The Alarm condition can only be reset by a RESET ALARM/GAS RELEASED operation.

manipulated
RESET ALARM/GAS RELEASED operation:

2. Press the RESET ALARM/GAS RELEASED button on the UI panel
3. The system will restore the functional conditions as follows:
a. During the Reset ALARM/GAS RELEASED operation the ALARM LED will blink; in
case the GAS RELEASED LED and PRE-ALARM LEDs were on before the RESET
ALARM/GAS RELEASED operation, these LEDs will blink as well
b. In case the system has released the gas, the aspiration fan will be switched on
again and the system will resume its smoke detection function
c. The Alarm condition (No Alarm, PRE-ALARM 1, PRE-ALARM 2, ALARM) will be
restored after 20 seconds, based on actual smoke level and Manual Activation
