5 Testing/Maintenance
When finished with the original installation and all modifications, conduct a complete operational test on the entire installation to verify compliance with applicable
NFPA standards. Testing should be conducted by a factory-trained fire alarm technician in the presence of a representative of the Authority Having Jurisdiction and the
owner’s representative. Follow procedures outlined in NFPA Standard 72’s section on Inspection, Testing and Maintenance. All test and maintenance instruction codes
and software necessary to provide test and inspection requirements of CAN/ULC-S536, Standard for the Inspection and Testing of Fire Alarm Systems.

been acknowledged. It is programmed as “switch inhibit”.
CONTROL NAC Y Supervised NAC
GEN ALARM N Control Module, an XPC-8 circuit, or an XP5-C (in NAC mode) configured as a Municipal Box Transmitter for
NFPA 72-2002 Auxiliary Fire Alarm Systems applications (MBT-1 required). This Type ID can also be used for
general alarm activation. It is programmed as “switch inhibit”.

type). It is programmed as “switch inhibit”.
GEN TROUBLE N
Control Module, an XPR-8 relay, or an XP5-C (in relay mode) activated under any System Trouble condition. It is programmed
as “switch inhibit”.
GENERAL PEND N
Control Module, an XPC-8 circuit, or an XP5-C (in NAC mode) that will activate upon receipt of an alarm and/or trouble
condition, and remain in the ON state until all events have been ACKNOWLEDGED.
TROUBLE PEND N
Control Module, an XPC-8 circuit, or an XP5-C (in NAC mode) that will activate upon receipt of a trouble condition, and remain
in the ON state until all troubles have been ACKNOWLEDGED. It is programmed as “switch inhibit”.

NOTE: Use 0 (zero) ohm impedance when testing wire-to-wire faults.
WARNING: DO NOT USE SOFTWARE FOR RELEASING LOCKOUT
DO NOT RELY ON DISABLE/ENABLE SOFTWARE SETTINGS TO LOCK OUT RELEASING DEVICES. RELEASING DEVICES
MUST BE PHYSICALLY DISCONNECTED.
NOTE: When an input or output point associated with releasing functions is disabled, a single supervisory trouble will be generated.
