7.10 Emergency Procedures
7.10.1 Identifying Alarm Sounds
Your alarm system may be programmed for a steady alarm sound
or a pulsed alarm sound. It is important to learn the difference
between a fire alarm sound and an intrusion alarm sound before
you are confronted with an actual emergency.
7.10.2 Silencing Alarms
All alarms can be silenced with any PIN that has disarm privileges.
Entering your [PIN]+ [Off] will silence the alarm and turn off (disarm)
the control.
7.10.3 A Cautionary Note
How you respond to an alarm will depend, mostly, on the type and
time of the alarm. You should seek the advice of your installing
company as they install your system, not later (e.g. after an alarm)
to develop a response plan.
7.10.4 Use Common Sense
Above all else, common sense should prevail. If there is any threat
or hint of danger to yourself or others on the premises, such as in
the event of a fire alarm, everyone should be instructed to leave the
premises immediately. Do not enter the premises unless
accompanied by the appropriate Emergency Services’ personnel,
or after they have given the OK to enter.
7.10.5 Caution When Entering A Building
If the bells and sirens are on and/or the red Armed Light is flashing
with the DS7447 display reading “Zone Alarm” or the DS7445 having
its zone LEDs flashing, then the keypad is signaling that an alarm
has occurred. The keypad will also issue a pulsed tone during the
entry delay instead of the usual steady tone.
If the alarm has not been previously investigated, do not enter the
building unless accompanied by the appropriate Emergency
Services’ personnel.
7.10.6 Fire Alarms
Fire Alarms are silenced using the same procedure as intrusion
alarms: a [PIN] (with disarm privileges) + the [Off] key.
The Fire Alarm system is not reset until alarms at smoke detectors
are cleared by using the System Reset command. The Fire Alarm
system will not be functional until this procedure has been followed.
See the “Fire Reset” section, 7.11.1.
7.11 Fire Reset/Fire Trouble
7.11.1 Fire Reset
During a fire alarm, exit the premises immediately. When you have
determined there is no fire, you may silence the bells/sirens before
you initiate the System Reset command: [PIN] + [System Reset].
Before the System Reset command is used, determine which smoke
detector has alarmed so the monitoring company may verify its
operation.
To use the System Reset command sequence, your PIN
must have disarm privileges. The System Reset command
will perform a fire reset, a battery test and will clear all
system troubles.
If the System Reset command has not been performed
after 24 hours of the Fire Alarm, the keypad will sound and
display “Fire Alarm Not Reset.” If the sounders have been
silenced and the system has been reset properly, this
warning will not occur.
7.11.2 Fire Trouble
A Fire Trouble message with a zone number signifies a problem
with the fire system, such as a break in the wiring that monitors
smoke detectors. A Fire Trouble message with no zone number
indicates a ground fault if the unit is in the commercial fire mode.
A Fire Trouble will be indicated by a short beep from the keypad
sounders every 10 seconds. The DS7447 will display “Fire Trouble”
followed by the zones in a trouble condition. The DS7445 will turn
the Fire and Trouble Lights on steady and will light the corresponding
zone LEDs.
Notify your installing company immediately if the Fire Trouble
message is displayed.
The Fire Trouble beep can be silenced with any [PIN] followed by
the [Off] key. After problems have been remedied, a [PIN] followed
by the [Off] key should again be entered to clear the “Fire Trouble”
display.
7.11.3 Dirty Chamber
A Dirty Chamber display, followed by a zone number and
accompanied by a beep every ten seconds indicates that the smoke
detector for that zone requires cleaning or replacement. The smoke
detector will also give a Dirty indication by flashing its LED once
per second.
The Dirty Chamber beep can be silenced with any [PIN] + the [Off]
key.
Notify your installing company immediately if the Dirty Chamber
message is displayed.
