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
