PART 12:  USER OPERATION

12.1 TROUBLE DISPLAY 

The Spectra system continuously monitors fourteen possible trouble conditions. When a trouble condition occurs,
the [

] key or [

] indicator will illuminate on the LED keypads or “Trouble” will appear on the LCD keypad’s

screen. Press the [

] or [

] key to switch to the Trouble Display. The [

] key or [

] indicator will flash and

lights corresponding to an existing trouble condition will illuminate on the LED keypads (see Table 10) or the
appropriate trouble message will appear on the LCD keypad. Press the [

] key to exit the Trouble Display. 

Please note that the keypad can be programmed to emit a 

BEEP

 every 5 seconds whenever a new trouble condition

has occurred. Pressing the [

] or [

] key will stop the beeping.

Table 10: Trouble List

[1]

No/Low Battery Failure

The control panel performs a dynamic battery test under load every 60 
seconds. This trouble indicates that the back up battery is disconnected or 
that the battery should be replaced, as it will not provide adequate current 
in case of AC loss. This trouble will also appear when the control panel is 
running on battery power and the battery voltage has dropped to 10.5 volts 
or lower. This means the battery must be recharged or replaced.

[2]

Wireless Transmitter 
Low Battery

The battery voltage of a wireless transmitter has dropped below 
recommended limits. If connected to a SPC-319, press [2] to view the 
zones that are generating this trouble. If connected to an Omnia (OMN-
RCV3), the trouble will be displayed as a global trouble. To determine the 
zones generating the trouble, examine the Low Battery LED indicators on 
all the transmitters. The batteries should be replaced.

[3]

Power Failure

Upon power failure, the AC LED on all keypads will turn off. The control 
panel can transmit the report code programmed in section [205]. This 
report code can be delayed by programming a Power Failure Report Delay 
in section [086]. The AC LED turns back on as soon as power is restored.

[4]

Bell Disconnected

This trouble occurs when a bell or siren is not connected to the bell output 
terminals. If you are not using the 

BELL

 terminals, connect a 1K

Ω resistor 

across the bell output. 

[5]

Maximum Bell Current

The 

BELL

 output uses a fuseless circuit and will automatically shut down if 

the current exceeds 3A. After opening the short or reducing the load, the 
bell current is restored upon the following alarm generation. This trouble 
indicator will only appear when a condition has occurred that would 
activate the bell output (e.g. during an alarm). 

[6]

Maximum Auxiliary Current The auxiliary output uses a fuseless circuit to protect the power supply 

against current overload and automatically shuts down if the current 
exceeds 1.1A. After opening the short or reducing the load, the panel will 
restore power to the auxiliary output.

[7]

Communicator Report Fail

The control panel has failed all attempts to communicate with the central 
monitoring station.

[8]

Timer Loss

The control panel’s internal clock must be re-programmed. To re-program 
the timer press the [8] key followed by the current time using the 24-hour 
clock (i.e. 8:30PM = 20:30).

[9]

Tamper/Zone Wiring Fail

If the Tamper Recognition options are enabled (see page 30), this trouble 
indicates a wiring problem on one or more zones or that the cover has 
been removed on one or more wireless transmitters. To provide line short 
recognition the zone connections must have EOL resistors. If you press 
the [9] key, the keypad will display which zones are in trouble. Enter the 
Installer Code to clear Tamper troubles.
