Normal Mode
In the Normal Mode, the panel is operating properly and has not detected any Alarm, Supervisory, or
Trouble conditions. The green power LED is ON and all other LEDs are OFF in the normal mode.

Alarm Mode
When a fire alarm condition is detected, the common alarm LED is ON (RED), and the panel is in Alarm
Mode. If the alarm occurs while in trouble or supervisory mode, the panel displays the system trouble LED
steady ON, and silences the trouble buzzer. The trouble relay continues to indicate panel trouble. Zone
Trouble and Supervisory LEDs not in conflict with the alarm LEDs remain ON.

WARNING

Do NOT silence fire signals until certain that a fire condition does not exist.

In the alarm mode, the Indicating Appliance Circuits operate as programmed. The system alarm LED turns
on, the alarm relay operates, and the Relay/City-Tie Module transmits a fire alarm condition, if so
configured. The red IDC zone LED lights, indicating the area of the alarm. The appropriate alarm zone
LED on the Remote Annunciator operates via the Annunciator Driver Module. The dialer will transmit a
zone specific alarm signal to the Central Monitoring Station.

To silence the Indicating Appliances, press the

ALARM SILENCE

switch. Indicating Appliance Circuits will not

respond to the

ALARM SILENCE

switch until all waterflow zones are no longer in the active alarm condition.

Reactivation of the waterflow zone will reactivate the IACs.
