Special Zone Outputs Coding Functions for NACS
:
Before selecting an output for Two-stage coding, note the following:
The control panel automatically sends an Alert Signal to any of the four NACs mapped to Z00 and
F8, but not mapped to the alarm signal. After five minutes without an acknowledge or silence, the
Alert Signal changes to Temporal pattern.
Two-stage Canada 3 and 5: Function the same as Two-stage except the second stage is achieved
when
• The three or five minute timer expires without an acknowledge or silence.
OR
• The Drill Switch (or an input programmed with the type code
DRILL SWITCH or
EVACUATE SW) is activated.
OR
• A CBE event has occurred on the device containing both General Alarm Z00 and a general
zone (Zones 1-Z99) or logic zone (Logic Zones 1-20).
If Acknowledge or Silence is pressed within the three or five minute timeout period, the NAC will
remain at first stage. Subsequent alarm(s) will restart the timer.
Two-stage Canada Manual: Functions the same as Two-stage except the first stage will continue to
sound until a CBE event for that device or a Drill is activated. Subsequent alarms will not activate
the second stage. If a panel Reset or Silence occurs before a Drill or CBE event occurs, the second
stage will not sound.

Two-Stage Canada 3 Alert Signal - 20 PPM;
Drill Switch activated, 3 minute timer has expired, or device’s CBE Zone activation (Z00 plus Zones
1-99 or Logic Zones 1-20) - Temporal (3 min. timeout)
Two-Stage Canada 5 Alert Signal - 20 PPM;
Drill Switch activated, 5 minute timer has expired, or device’s CBE Zone activation (Z00 plus Zones
1-99 or Logic Zones 1-20) - Temporal (5 min. timeout)
Two-Stage Canada Manual Alert Signal - 20 PPM;
Drill Switch activated or device’s CBE Zone activation (Z00 plus Zones 1-99 or Logic Zones 1-20) -
Temporal
System Sensor Strobe Synchronizes System Sensor Horn/Strobes (Applies to NAC on CPU2-640 only)
Note: If the “Strobe” Type ID is used with System Sensor Strobe synchronization,“*” will silence the
horn portion only, and resound will occur only by fire alarm. F, U, B, T, or O will silence the entire
circuit. Refer to “Modify an Addressable Control Module Point” on page 23 and “Modify NAC Points”
on page 24
Gentex Strobe Synchronizes Gentex Horn/Strobes (Applies to NAC on CPU2-640 only)
Note: If the “Strobe” Type ID is used with Gentex Strobe synchronization,“*” will silence the horn
portion only, and resound will occur only by fire alarm. F, U, B, T, or O will silence the entire circuit.
Refer to “Modify an Addressable Control Module Point” on page 23 and “Modify NAC Points” on
page 24
Wheelock Strobe Synchronizes Wheelock Horn/Strobes (Applies to NAC on CPU2-640 only)
Note: If the “Strobe” Type ID is used with Wheelock Strobe synchronization,“*” will silence the horn
portion only, and resound will occur only by fire alarm. F, U, B, T, or O will silence the entire circuit.
