Operating Instructions
Understanding the Keypad
This keypad is a full-function system controller and annun-
ciator. The illuminated keypad has a 16-character vacuum
fluorescent display (VFD) and a sounder that emits distinct
condition tones to alert you to fire alarm, fire trouble, or fire
supervisory events as they occur. In conjunction with the VFD
and the sounder, four status LEDs provide the following system
status indications: Fire, Silenced, Supervisory, and Trouble.
Keypad Operation
The vacuum flourescent
display (VFD) shows system
alarm and trouble messages:
The pre-programmed custom
text describes the specific point
and its location.
The built-in sounder emits the
following warning tones:
Fire signal: pulsed, high-
pitched bell tone during fire
alarm.
Trouble signal: two-tone
warble during a trouble event.
Invalid key buzz: buzz tone
when invalid key is pressed.
Keypad encoding tone:
muted beep tone as each key
is pressed.
Normal Operation: When the system is operating normally and is disarmed, the display shows the programmed idle text. The
default system normal message is * FIRE SYSTEM *.
Fire Alarm Operation: When an alarm occurs, the Fire LED activates, and the keypad emits a pulsing high-pitched fire tone.
The tone sounds for a pre-programmed length of time. A display message appears that describes the first point that entered an
alarm. Press the NEXT key to acknowledge the alarm. To view and acknowledge additional points that are in alarm, press NEXT
repeatedly. The display shows Ax ## FIRE ALARM (x = the area number; ## = the number of fire alarms in Area x).
Fire Trouble Operation: When a trouble condition occurs (such as wiring for a point is cut, AC power fails, and so on), the
keypad sounder activates briefly approximately every six seconds. The Trouble LED illuminates and Ax ## FIRE TRBL or the
highest priority system trouble appears in the display. Press the NEXT key to acknowledge the trouble. To view and acknowledge
additional system or point troubles, press NEXT repeatedly.
Fire Supervisory Operation: When a supervisory condition occurs, the sounder activates briefly approximately every six
seconds. The Supervisory LED illuminates and Ax ## FIRE SUPV appears in the display. Press the NEXT key to acknowledge
the supervisory condition. To view and acknowledge point supervisory conditions, press NEXT repeatedly.
