FA-265 Installation and Operator’s Manual

5.0 Panel Operation

5.1 Operating Sequences

This section describes how the panel functions under various conditions. The choices you make in panel

programming will also affect how the panel operates. Please see “6.0 Programming the FA-265 System” on

page 24 for information on how to program the panel, and descriptions of each of the programming options.

5.2 General Zone Fire Alarms

Zone alarms have priority over all other annunciation. When an alarm occurs, the following happens:

•The corresponding zone alarm LED begins flashing, the common alarm LED turns on steady, and the alarm

relay turns on.

•If a trouble was present on that zone then the zone trouble LED turns off. If the trouble buzzer is audible

then it also turns off.

•The NACs sound in a steady or temporal pattern, depending on the option selected (see “Steady” on

page 27).

•If enabled, the silence inhibit timer begins counting down (see “Silence Inhibit and Walk Test Programming

- Section 3 (‘Battery’ LED on steady)” on page 28). If the silence inhibit timer is enabled, the panel cannot be

silenced for 60 seconds following the first fire alarm. Subsequent fire alarms do not restart or extend this

timer. While the signal silence inhibit timer is counting down, if the Silence Alarm button is pressed the panel

will sound a 1 second ‘error tone’ on the common trouble buzzer.

•The NACs remain on until silenced with the Silence Alarm button, or if the automatic alarm silence is

enabled, until the thirty minute bell timer runs out (see “NAC Auto-silence and Strobe Programming - Section

2 (‘NAC2’ LED on steady)” on page 27). If the automatic silence timer is enabled, the panel will automatically

silence the NACs 30 minutes after the last fire alarm. Each zone alarm will restart the timer, giving a full 30

minutes after the last alarm before the NACs are silenced.

• Once the NACs are silenced the signals silenced LED turns on and any flashing zone alarm LEDs turn on

steady. The common trouble LED and trouble relay also turn on and, if the NACs have been silenced

automatically, the buzzer will sound at a rate of ½ second ON/OFF.

•Any additional zone alarms that occur while the panel is in alarm will reset the auto alarm silence timer and

turn on the NACs, but the panel will not restart the 60 second silence inhibit timer.

•The zone alarm LEDs, common alarm LED and alarm relay will remain on steady until a system reset is

performed.

5.3 Waterflow Alarms

If the Waterflow Silence option is turned off (see “Waterflow Programming - Section 4 (‘Ground Fault’ LED on

steady)” on page 28), when a waterflow zone (type 03) initiates an alarm the NACs cannot be silenced until all

waterflow zones are returned to normal. If all waterflow zones return to normal after the 30 minute automatic

signal silence timer has expired, then the panel will silence the NACs.

If the Waterflow Silence option is turned on, then an alarm on a waterflow zone is treated like any other fire

alarm.

Note: A manual signal silence will not initiate the trouble buzzer. Only the common trouble LED and

signals silenced LED are turned on.
