FS-250 Installation and Operation Manual

• PRE-SIGNAL

A point activated by a PRE-SIGNAL alarm device activates the alarm relay, alarm DACT,

alarm LEDs and buzzers, and all user programmed outputs normally, except NACs. Only

pre-signal NAC(s) operate at this time. Pre-signal NACs are for constantly attended central

locations manned by trained building personal.

Operation of the SYSTEM RESET button within the pre-programmed time (60-180

seconds) after initiation of the pre-signal prevents operation of the general alarm and thus

the general alarm NACs.

Failure to act within the pre-programmed time (60-180 seconds) will result in activation of

the general alarm and thus the general alarm building NACs.

Receipt of a general alarm during the delay period immediately sounds the general alarm

building NACs.

When the alarm condition has been corrected, return the system to standy operation by

pressing he SYSTEM RESET button.

Do not reset the system until the alarm condition has been cleared. The LCD display will

indicate the area in which the alarm was detected. The detector or module associated with

the device initiating the alarm will display a light indicating activation (if applicable).

Trouble Conditions

In case of a trouble condition, the system trouble LED and any programmed trouble LEDs

will be flashing, the LCD display will identify the problem, and the buzzer will sound. Refer

to the applicable section of the system manual to determine the probable cause of the

trouble and the action to be taken.

When a trouble has been noted, the buzzer may be silenced by pressing the

ACKNOWLEDGE button. The trouble LEDs will change to a continuous display. If the

trouble has not been corrected when the trouble re-ring timer expires, the trouble display

will revert to its original condition and the buzzer resound.

If the control panel is programmed for trouble acknowledge required, when the indicated

trouble condition has been cleared, the system will revert to standby condition after the

ACKNOWLEDGE button is pressed.

Some trouble conditions require a system reset to restore the control panel.
