[*] [2] Trouble Announcements

The system constantly monitors itself for several different trouble conditions. If a

trouble condition is present, the System light will be ON and the keypad will beep

twice every 10 seconds. The trouble beep can be silenced by pressing any key on

the keypad. If Bell Squawk on Trouble is enabled (section [014], option[5]), the

bell will squawk every 10 seconds when a trouble condition is present.

To listen to an announcement of trouble conditions:

1. Press [✱] [2].

2. The system will announce each trouble condition.

Possible trouble conditions are described below:

Service Required: The system has one or more of the following problems:

• Low Battery: Main system backup battery charge is low. Trouble is restored

when the battery is fully charged.

• Remote Sounder Supervisory Trouble: The remote sounder is disconnected.

• Bad Module Placement: One or more devices have not passed the Placement

Test.

• System Fault: Internal error on the system, return for repair.

The NT9010 will only announce “Service Required”. If the control unit announces

this trouble, users can press [1] to expand the troubles. The user should call for

assistance. The specific trouble will be logged in the event buffer.

AC Failure: AC power is no longer being supplied to the NT9010 control unit. To

conserve power, when there is an AC Failure all lights will turn off, except for the

flashing System light.

Telephone Line Monitoring Trouble (TLM): There is a problem with the tele-

phone line (See 2.3.15 Telephone Line Monitoring (TLM) on page 49.)

Failure to Communicate (FTC): The communicator failed to communicate with

any of the programmed telephone numbers (see 2.3.8 Communicator Dialing on

page 39).

Zone Fault (including Fire Zone): A zone on the system is experiencing trouble.

This means that a zone could not generate an alarm on the system if required to do

so (e.g. a fire zone is open, or a supervisory fault on a wireless zone). When a zone

fault occurs, the unit will start to beep. Press [5] while in Trouble mode to hear an

announcement of the affected zones.

NOTE: A Fire zone trouble will be generated and announced in the armed

state.

Zone Tamper: The tamper switch is open on a wireless device. When a tamper

condition occurs, the NT9010 will start to beep (if the system is armed, an alarm

will occur). Press [6] while in the Trouble mode to hear an announcement of the

affected zones. If a zone is tampered or faulted, it must be fully restored to clear

the trouble. If a smoke detector is tampered, the Ready light will remain on and the

system can be armed.

NOTE:Once a zone is tampered or faulted, it must be completely restored

before the trouble condition will clear.
