[ ] [2] Trouble Display
The panel constantly monitors itself for several different trouble
conditions. If a trouble condition is present, the Trouble (or
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 any 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 view trouble conditions from an LED keypad:
1. Press [ ] [2].
2. The keypad will flash the Trouble (or System) light. The zone
indicator lights corresponding to the present trouble
conditions will be ON.
When using an LCD keypad, the trouble conditions will be listed
on the display; simply use the arrow (< >) keys to scroll through
the list of present trouble conditions.
Troubles can be viewed while armed using the
LCD keypad, provided the keypad is version 2.0 or
later. Older keypads will incorrectly display "Fire
Trouble". If using older LCD keypads, program-
ming section [013], option [3] as OFF will ensure
troubles are displayed correctly.
The various troubles are described below:
Light Trouble
1 Service Required : Press [1] to determine the specific
trouble. Lights 1 - 5 will light up to indicate the trouble:
• Light [1] – Low Battery: Main panel backup battery
charge is low (below 11.5 volts under load).Trouble is
restored when the battery charges over 12.5 volts.
• Light [2] – Bell Circuit Trouble: The bell circuit is open
(see Section 5.13 "Siren").
• Light [3] – General System Trouble: The printer
connected to the PC5400 Printer module has a fault
and is off-line.
• Light [4] – General System Tamper: Tamper has been
detected in a module.
All tamper conditions must be physically restored
before the trouble condition can be cleared.
• Light [5] – General System Supervisory: The panel
has lost communication with a module connected to
the Keybus (see Section 2.6 "Supervision"). The event
buffer will log the event.
• Lights [6-8] – Not used
2 AC Failure : AC power is no longer being supplied to the
control panel. The Trouble (or System) light will flash if
an AC Failure is present, if the Trouble Light Flashes if
AC Fails option is programmed (section [016], option
[2]). This trouble will not be displayed if the AC Trouble
Displayed option is disabled (section [016], option [1]).
See section 5.8 "Communicator Reporting Codes" for
information on AC trouble reporting.
3 Telephone Line Monitoring Trouble (TLM) : There is a
trouble with the telephone line (See section 5.12
"Telephone Line Monitor".)
4 Failure to Communicate (FTC) : The communicator failed
to communicate with any of the programmed telephone
numbers (see section 5.5 "Communicator - Dialing").
Zone Fault (including Fire Zone) : A zone on the system is
5
experiencing trouble, meaning that a zone could not provide
P A D V C O
an alarm to the panel if required to do so (if a fire zone is open,
or there is a short on a DEOL zone, or a supervisory fault on
a wireless zone). When a zone fault trouble condition
occurs, the keypad(s) on the system will start to beep. Press
[5] while in Trouble mode to view the affected zones.
A Fire zone trouble will be generated and dis-
played in the armed state.
6 Zone Tamper : A zone configured for Double End Of Line
resistor supervision has a tamper condition, or the
tamper switch is open on a wireless device. When a
tamper condition occurs, the keypad(s) will start to
beep. Press [6] while in the Trouble mode to view the
affected zones. If a zone is tampered or faulted, it must
be fully restored to clear the trouble.
By enabling Tampers/Faults Do Not Show as Open
in section [013], option [4], Faults and Tampers will
not show as open on the keypad, and will be
hidden from the end user. If the option is disabled,
Faults and Tampers will show as open.
Once a zone is tampered or faulted, it must be
completely restored before the trouble condition
will clear.
Device Low Battery : A wireless device has a low battery
7
condition. Press [7] one, two, or three times to view
which devices are experiencing battery failure. An LED
keypad will indicate battery failure using zone lights 1 to
8. The following will occur:
Press [7]
Press [7] again
Press [7] again
8 Loss of System Time : When the panel is powered up, the
internal clock needs to be set to the correct time. This trouble
is cleared when an attempt is made to reset the clock.
[ ] [3] Alarm Memory
The Memory (or System) light will be on if any alarm occurred
during the last armed period or – in the case of 24 hour zones –
if an alarm occurred while the panel was disarmed.
To view alarm memory, press [ ] [3]. The keypad will flash the
Memory (or System) light and the zone indicator lights corresponding
to the alarm or tamper conditions which occurred during or since the
last armed period. To clear the Memory (or System) light, arm and
disarm the system.
[ ] [4] Door Chime On/Off
The door chime feature is used to sound a tone from the keypad
whenever a zone programmed as a chime zone is activated (see
Section 5.3 – "Zone Attributes"). If the door chime feature is
enabled, the keypad will emit five short beeps whenever a chime
zone is activated. Designated entry/exit doors are often defined
as chime zones. The feature can be turned on or off while the
system is armed or disarmed.
