Appendix H Special Zones
H.1 Overview
This appendix provides descriptions and options for the following Special Zones:
Table 60 Special Zones
Note: Special Zones 91–94 are covered in Appendix D “Releasing Applications”
.
Special Zone 99 is covered in Appendix G “Pre-Alarm (AWACS™) Applications”.
H.2 Presignal and Positive Alarm Sequence (PAS)
The control panel delays activation of outputs containing Z90 in their
Control-By-Event (CBE) equation for all alarm initiating devices that contain Z90 in
their Control-By-Event equation. A subsequent alarm will abort the delay and execute
CBE equations. If using Z90, note the following:
• Do not include Z90 in the CBE equation for a releasing device.
• Z90 must be mapped to all participating outputs.
• Abort circuit activation by pressing Alarm Silence before the delay expires.
H.2.1 Presignal
You can set Presignal delay time between 60 and 180 seconds. Presignal delay does not
apply to the following:
• the System Alarm relay;
• the 4XTM polarity reversal alarm output;
• the 4XTM municipal box output; and
• the RTM-8 output.
H.2.2 Positive Alarm Sequence (PAS)
Do not include Z90 in the CBE equation for any monitor module that connects to a
device other than an automatic fire detector. NFPA 72 requires installation of a PAS
Inhibit switch. To do this, use a monitor module with type code “PAS Inhibit.”.
Selected outputs (set to PAS=Y) delay for 15 seconds. Pressing Acknowledge within
the 15-second delay increases the delay to the full programmed value (60–
180 seconds). When an alarm comes from an initiating device with a CBE equation that
includes Z90, the control panel delays the following outputs:
• the System Alarm relay;
• the 4XTM Polarity Reversal Alarm output; and
• the 4XTM Municipal Box output.
Note: PAS will not delay RTM-8 relay outputs.
