Presignal is a feature that initially causes alarm signals to only sound in specific areas,
monitored by qualified persons, where activating a general alarm requires human
verification. This allows delay of the alarm up to 180 seconds after the start of alarm
processing. The control panel Presignal feature provides two selections:

• A
Presignal Delay Timer
(60-180 seconds) that delays activation of all outputs
with a CBE that includes Special Zone F0.
• A
PAS
(Positive Alarm Sequence) selection, in addition to the
Presignal Delay
Timer
, that allows a 15-second time period for acknowledging an alarm signal
from a fire detection/initiating device. If the alarm is not acknowledged within 15
seconds, all local and remote outputs activate immediately and automatically.
Figure 78 contains an illustration of Presignal and PAS timing.

The control panel delays activation of outputs containing F0 in their Control-By-Event
(CBE) list for all alarm initiating devices that contain F0 in their CBE list. A subsequent
alarm will abort the Presignal Delay Timer and execute CBE lists.

• NFPA 72 requires installation of a PAS Inhibit switch, that you can use to turn off
the PAS delay timer when the control panel is unattended. Do so by programming a
monitor module with the Type Code,
PAS INHIBIT
. For details, refer to "How to
Program a Monitor Module" on page 23.
• Abort circuit activation by pressing the
ALARM SILENCE
key before the Presignal
Delay Timer expires.
• Program zone F0 to participating inputs and outputs.

• Do not include F0 in the CBE list for a releasing device.
• Do not include F0 in the CBE list for any monitor module that connects to a device
other than an automatic fire detector.
