PART 15: USER OPERATION
15.1 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 Table 10) 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”.
Table 10: Trouble List
LED # 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
battery 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 There is no bell or siren connected to the bell output terminals of the control panel. If you
are not using the
BELL
, connect a 1KΩ resistor across the bell terminals.
[5]
Maximum Bell Current The
BELL
output uses a fuseless circuit and will automatically shut down if the current
exceeds 3A (1725, 1725EX, 1728 and 1728EX) or 2.5A (1758 and 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 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 29), this trouble indicates a wiring
problem on one or more zones or that the cover has been removed on one or more wireless
transmitters. In order 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.
[10] Telephone Line Monitoring If the Telephone Line Monitoring (TLM) feature is enabled (see section [135]), this trou-
ble indicates that the control panel has not detected the presence of a telephone line for
30 seconds.
[
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
keypad 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.
