USER OPERATION
TROUBLE DISPLAY
The Spectra system continuously monitors fourteen possible trouble conditions. When a trouble condition occurs, the [
TBL
]
button or [
TRBL
] indicator will illuminate on the LED keypads or “Trouble” will appear on the LCD keypad’s screen. Press the
[
TBL
]
or
[
TRBL
]
button to switch to the
Trouble Display
. The
[
TBL
]
button or
[
TRBL
]
indicator will flash and lights corresponding
to an existing trouble condition will illuminate on the LED keypads (see below) or the appropriate trouble message will appear
on the LCD keypad. Press the
[
CLEAR
]
button 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
[
TBL
]
or
[
TRBL
]
button will stop the “beeping”.

Description
Details
[1]
No/Low Battery Failure
The control panel performs a dynamic battery test under load every 60 seconds. This trou-
ble indicates that the back-up battery is disconnected or that the battery should be
replaced, as it will not provide adequate back-up 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
This means the battery voltage of a
Liberator
wireless transmitter has dropped to 6.5V or
less. Also, the yellow LED on the transmitter can flash to indicate this trouble. The bat-
tery should be replaced.
[3]
Power Failure
Upon power failure, the AC LED on all keypads will turn off. The control panel can trans-
mit 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 or PGM2 Disconnected
There is no bell or siren connected to the bell output terminals of the control panel or there
is no device connected to the PGM2 terminals (1755, 1755EX, 1758 and 1758EX only). If
you are not using the
BELL
or
PGM
2 terminals, the trouble indicator will always be on. To
avoid this, connect a 1K
Ω
resistor across the bell or PGM2 output.
[5]
Maximum Bell Current
The
BELL
output uses a fuseless circuit and will automatically shut down if the current
exceeds 3A with a 1725, 1725EX, 1728, or 1728EX or 2.5A with a 1755, 1755EX, 1758,
or 1758EX . 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
occured 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 and enter 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, this trouble indicates a wiring problem on
one or more zones or that the cover has been removed on one or more wireless transmit-
ters. In order to provide line short recognition the zone connections must have EOL resis-
tors. If you press the
[9]
key, the keypad will display which zones are in trouble.
[10]
Telephone Line Monitoring
If the Telephone Line Monitoring (TLM) feature is enabled (see section [135]), this trouble
indicates that the control panel has not detected the presence of a telephone line for 30 sec.
[
STAY
]
OR
[11]
Fire Loop Trouble
Denotes a wiring problem on zone 3, if defined as a Fire Zone.
[
FORCE
]
or [16]
Keypad Fault
If the keypad is no longer communicating with the control panel, the [
TBL
] or [
TRBL
] will
flash, the [
FORCE
] key will illuminate (the LCD keypad displays “Keypad Fault”) and the
keypad will emit four consecutive beeps at 5-second intervals. Press any key on the key-
pad to terminate the “beeping” sequence. When communication has been restored, the
system will revert to previous status.
[
BYP
]
OR
[12]
Module Loss
A Liberator or zone module is no longer communicating with the control panel.
[
MEM
]
OR
[13]
Wireless Transmitter
Supervision Loss
One or more wireless transmitters are no longer communicating with the receiver. If you
press the [
MEM
] key, the keypad will display which zones are in trouble.
