How to Block Acknowledge an Alarm (NFPA 72 Local, 72 Municipal Tie, 72 Remote Station)
Silencing the System
Siemens Building Technologies
Fire Safety
Note the specific location of the alarm(s) by using the procedures described
above.
Unlock and open the door.
Press ALARM ACK to acknowledge all alarms. The System displays the
following message:
ALL ALARMS ACKNOWLEDGED
If your System includes the printer option, it prints the following message:
ACK Alarm
All Alarms Are Now Acknowledged.
If you press ALARM ACK again, the System displays:
ALL ALARMS ACKNOWLEDGED
The ALARM LED glows steadily to indicate that all alarms are acknowl-
edged. If there are no supervisories, troubles, or security conditions in the
System, the internal audible goes silent; if any of those conditions still exist,
the internal audible pulses.
Press AUD SIL after all alarms are acknowledged. The System displays the following
message:
AUDIBLES SILENCED
(Pressing AUD SIL a second time causes the internal audible and the System to
unsilence and the message AUDIBLES UNSILENCED to appear on Line 11 of the
display; thus, pressing AUD SIL alternately silences and unsilences the System.)
If your System has a printer, it prints a message similar to the following:
AUD. SILENCED/UNSIL. 11:01:00 Dec 31, 20
Audibles Silenced
11:59:59 Dec 31,20
