Trouble Display
The panel constantly monitors itself for several different trouble conditions. If a trouble condition is present
the ‘Trouble’ light will be on steady and all keypads will beep twice every 10 seconds.
The trouble beep can be silenced by pressing any key on any keypad.
To view trouble conditions:
1. Press [
✱
] [2].
2. The keypad will flash the ‘Trouble’ light and light zones to indicate which trouble conditions are present.
A description of the various troubles are as follows:
Trouble [1] - Service Required
This light will be on if any of the following trouble conditions are detected by the control panel; Low
Battery, Bell Circuit Trouble, General System Trouble, General System Tamper, General System
Supervisory, PC5204 Low Battery and PC5204 AC Failure.
If a ‘Service Required’ trouble is present press [1] to determine the specific trouble present. The following
is a list of the specific ‘Service Required’ trouble conditions:
• Light [1] - Low Battery
The main panel backup battery is low. The trouble will be generated if the battery drops below 11.5
volts under load and will restore when the battery charges over 11.8 volts.
• Light [2] - Bell Circuit Trouble
The panel will indicate this trouble if the Bell fuse is blown or the panel senses an open condition on the
bell circuit
(See
Section 5.12 “Siren Supervision”
).
• Light [3] - General System Trouble
This trouble will be present if the PC5204 Power Supply module has an AUX failure, PC5204 Output #1
Trouble, or a printer connected to the PC5400 Printer module has a fault (off-line).
• Light [4] - General System Tamper
This trouble will be indicated if a Tamper Zone violation on any module is detected.
• Light [5] - General System Supervisory
This trouble will be indicated if the panel loses communication with any module connected to the
Keybus
(See
Section 2.7 “Enable Supervision”
). The event buffer will log a detailed description of the
event.
• Light [6] - Not Used
• Light [7] - PC5204 Low Battery
The PC5204 module has a low backup battery.
• Light [8] - PC5204 AC Failure
The PC5204 module has lost AC power.
Trouble [2] - AC Failure
This trouble indicates that AC power is no longer being supplied to the control unit. If it is required to
communicate this to a monitoring station, program reporting codes in sections [349] and [350]. To inhibit
reporting of short duration power outages, a delay can be programmed in section [370].
Trouble [3] - Telephone Line Trouble
The telephone connection to the control unit is continuously monitored. If there is a problem with the
telephone connection, a trouble will be indicated after the delay programmed in section [370]. If the
system has a LINKS1000, this trouble can be reported to a monitoring station by programming reporting
codes in sections [349] and [350].
Trouble [4] - Failure to Communicate (FTC)
If the communicator fails in an attempt to communicate with any of the programmed telephone numbers,
this trouble will be generated. If a later attempt is successful, the FTC reporting code(s) programmed in
section [351] will be transmitted along with any other unreported events that occurred while the panel was
not able to communicate.
Trouble [5] - Zone Fault (including Fire Zone)
This trouble will be indicated if any zone on the system is in a trouble condition, i.e. it could not provide an
alarm to the panel if required to do so. When a trouble condition occurs, the keypad(s) on the affected
partition will start to beep.
Press [5], while in Trouble mode, to view which zones have a trouble condition. If 2-wire smoke detectors
are being used, a trouble on that zone will be indicated by the “Fire” LED.
Trouble [6] - Zone Tamper
This trouble is only generated by zones configured for Double End-of-Line Resistor Supervision. This
trouble is generated when a tamper condition is present. When a tamper condition occurs, the keypad(s)
on the affected partition will start to beep.
Press [6], while in Trouble mode, to view which zones have a tamper condition.
