Output activation – delay override
In the event of fire alarm, all outputs will activate as programmed automatically. That is, without any manual
intervention.
There is a special case where sounders or fire routing outputs have a programmed delay configured. In this
case, upon reception of an alarm, the fire panel will enter the “delayed activation” state. A “delayed activation”
involves that sounders and/or Fire Routing outputs are inactive for a pre-defined period after the reception
of an alarm. After being configured, delays can be manually activated and deactivated with user access level
2 by pushing the delays on-off button. They may also activate and deactivate periodically following a pre-
defined schedule.
During the “delayed activation” state, the “delay ON” LED will blink together with the corresponding
“Sounders ON” or “Fire routing ON” LED, indicating that these outputs will activate after the pre-programmed
delay has expired.
The output activation delay can be cancelled (delay override) by pushing the “delays ON/OFF” button or the
“sounders ON/OFF” button (no password is needed).
Note that the delayed activation can also be overridden by an alarm which has no delay programmed.
Typically, MCPs are configured to initiate the alarm notification without delay (the panel configuration allows
defining if delays apply to ¨MCP alarms or not). Therefore, MCPs can also be configured to override the
delays.

Resetting the fire panel
The fire alarm condition can only be reverted by the reset operation. The reset operation is triggered by
pushing the reset button and entering the operator or installer password.
The reset operation will revert the fire panel to the quiescent functional condition. That is, it will stop all the
alarm indications and clear all the alarm events from the screen. Note that, right after the reset, the panel
will re-evaluate the status of all its loop devices. Therefore, the system will immediately enter again into
alarm status if fire stimulus (from detectors and/or manual call points) are still present.
