4.8.2 Coding Operation (NAC only)
Zone 98—reserved for NAC coding functions—is only used by NACs listing zone 98.
You can select one of the four code types listed in Table 39:
Table 39 Zone 8 Type Codes
Notes on using coding functions:
• Control Modules. Zone 98 does not work if listed in the CBE of control 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
Temporal unless you press the
ACKNOWLEDGE/STEP key. Pressing the DRILL key on
the control panel changes the NAC pulse to Temporal pattern.
• Two-Stage Canada. Functions like standard Two-Stage except only the Manual
Evacuate will cause NAC to go to second stage. If acknowledge is pressed on first
stage, timer will not time out. Subsequent alarm will restart timer.
4.8.3 Presignal/PAS Operation
Zone 90 is reserved for pre-signal functions and is used to delay control points for
human verification. If zone 90 is included in a control or relay module or Notification
Appliance Circuit’s CBE list, it inhibits all other CBE. Detectors and Monitor Modules
must call out Zone 90 in their program to be included in the pre-signal/PAS operation.
When any alarm occurs and no PAS inhibit type monitor module is activated, Zone 90
activates. If a second alarm activates, or the
DRILL key is pressed, Zone 90 goes false. If
PAS is selected, and the Acknowledge key is not pressed within 15 seconds, Zone 90
goes false. At the first alarm, a programmable 0–180 second timer starts. If an Alarm
Silence occurs, the timer stops. If the delay timer expires, manual activation will
activate outputs mapped to Zone 90. 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.
