Operating Coding
Functions
Zone F8—reserved for NAC coding functions—is only used by panel NAC circuits
listing zone F8. You can select one of the four code types listed in Table 9:
Table 9 Zone F8 Type Codes
Notes on using coding functions:
CMX modules Zone F8 does not work if listed in the CBE of CMX modules.
Two-Stage When an alarm occurs, an NAC programmed for two-stage, and not
activated by another zone, pulses at 20 PPM. After 5 minutes, the NAC changes to
steady on unless you press <Acknowledge/Step>. Pressing <Alarm Activate> on the
control panel changes the NAC pulse to steady. ICM-4/ICE-4 modules do not support
Two-Stage and turn on steady.
ICM-4/ICE-4 modules To enable California Code, cut D35 on the ICM-4 modules. If
D35 is not cut, ICM-4/ICE-4 modules turn on steady.
Presignal/Positive Alarm
Sequence (PAS)
Operation
Zone F0 is reserved for Presignal functions. Zone F0 can be used to delay control
points until an operator verifies an active control point. If including zone F0 in a CMX
or NAC CBE list, zone F0 overrides all other CBE actions. Detectors and monitor
modules must list zone F0 in the CBE to be included in the Presignal/PAS operation.
Table 10 Presignal Operation
At the first alarm, a programmable 0–180 second timer starts. If a Signal Silence
occurs, the timer stops. If the delay timer expires, manual activation will activate
outputs mapped to zone F0. The System Alarm relay, the 4XTM Polarity Reversal
Alarm Output, and the 4XTM Municipal Box Output delay if PAS is selected, but do
not delay for Presignal operations
Code Signal
March Time (default) 120 PPM (Pulses Per Minute)
Two-Stage Alert signal – 20 PPM; General alarm signal: Steady on
California 10 sec. on, 5 sec. off, repeats
Temporal 0.5 on, 0.5 off, 0.5 on, 0.5 off, 0.5 on, 1.5 off, repeats
If... And/or... Zone F0
an alarm occurs and there is no PAS inhibit type MMX activates
a second alarm activates or you press the alarm activate key, goes false
you select PAS and you do not press ACKNOWLEDGE
within 15 seconds
goes false
