Sensiscan 2000 Operating Instructions
NORMAL STANDBY OPERATION
:
1) The green AC POWER indicator must be lit, 2) all alarm (red LEDs) and trouble
indicators (yellow LEDs) should be off.
ALARM CONDITION: Activation of a compatible detector or any normally open fire alarm initiating device will result in the
following action by the System 500 control panel: 1) activate alarm notification, control, and signaling outputs as programmed,
2) light the Red SYSTEM ALARM LED and the associated initiating circuit alarm LED(s), and 3) A steady audible tone will sound
until the alarm is acknowledged or silenced. The controlled outputs will remain activated and the associated alarm LEDs will
flash until the alarm has been silenced or acknowledged, or the system has been reset.
If PRESIGNAL DELAY has been pro-
grammed, the activation of all
silenceable output circuits will be de-
layed by the time marked at right. For
Positive Alarm Sequence (PAS): If the
ACKNOWLEDGE or SILENCE keys
are not pressed within 15 seconds of
initiation of a first (and only) alarm,
output signals will be activated. Other-
wise, the programmed PAS 1, 2, or
three-minute time delay will take effect.

If SIGNAL SILENCE INHIBIT has
been programmed, Signal Si-
lence will not function for the in-
hibit time marked at right.
ACKNOWLEDGE (SILENCE TONE): Depressing the ACKNOWLEDGE switch will turn the audible tone off and switch
operation of associated LED(s) from flashing to steady. New alarms and/or troubles will resound the audible tone and flash
their associated LED(s).
ALARM SILENCING PROCEDURE: Alarm notification
appliance circuits, control relays and signalling circuits that
have been programmed as silenceable may be silenced by
depressing the SIGNAL SILENCE switch on the CPU control
panel (top left module). Subsequent alarms will reactivate
alarm outputs.
SIGNAL SILENCE should not pressed until it is
determined that an evacuation of the building is not required!

ALARM RESET: After locating and correcting the alarm condition, reset the control panel by depressing the SYSTEM
RESET switch on the CPU control panel (top left mod-
ule).
DISABLE/ENABLE: Refer to the System 2000 Installa-
tion Manual. WARNING: Disabling a circuit will reduce
or eliminate fire protection.
TROUBLE CONDITION: Activation of a trouble signal
under normal operation indicates a condition that re-
quires immediate correction. Carefully note which indi-
cators (LEDs) are illuminated and contact your local
service representative. The audible tone may be si-
lenced by depressing the ACKNOWLEDGE switch,
subsequent trouble(s) will reactivate the audible tone.
Trouble LEDs will continue to display the trouble
condition(s) until the trouble(s) is corrected.
