panel will detect a power loss if a continuous loss of AC (
?
12.5V) has occurred during the
period between two AC power tests (64 to 116 seconds). If a power loss remains present
throughout the
Power Failure Report Delay
(see section 6.9), the panel will transmit the
report code programmed at address 507 and the [
TRBL
] key will flash rapidly indicating a
power failure. The trouble indicator is restored if AC is detected during the dynamic battery
test. You can remove the power failure trouble indicator from the trouble display by enabling
the
Exclude Power Failure From Trouble Display
option (see section 10.10).
11.12.3 Bell Disconnected - Key [4]
The illumination of the [4] key indicates that there is no bell or siren connected to the bell
output terminals of the panel. Please note that when connecting a bell or siren to an optional
relay output the trouble indicator will always be on. To avoid this, connect a 1K
?
resistor
across the bell output. The control panel only recognizes bells or siren connected directly to
the bell output of the control panel not those connected through a relay.
11.12.4 Maximum Bell current - Key [5]
The bell output is microprocessor controlled and will automatically shutdown when the current
exceeds 3A. If this occurs, the [5] key will illuminate. 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 the bell is activated (i.e. during an alarm)
11.12.5 Maximum Auxiliary Current - Key [6]
The illumination of the [6] key indicates that the auxiliary current has exceeded 1A. This will
cause automatic shutdown of the auxiliary output. After opening the short or reducing the
load, the panel will restore power to the auxiliary output following the dynamic battery test
(approximately 60 seconds).
11.12.6 Communicator Report Failure - Key [7]
If the control panel was unsuccessful when attempting to communicate with the central
station computer or the Espload software the [7] key will illuminate.
11.12.7 Timer Loss - Key [8]
The illumination of the [8] key indicates that the control panel’s internal clock must be re-
programmed. To re-program the timer press:
[

+
2 digits (00 to 23) representing hours
+
2 digits (00 to 59) representing minutes

11.12.8 Tamper/Zone Wiring Failure - Key [9]
If the
Tamper/Wire Fault Recognition
Options (see section 10.7) are enabled, the [9] key will
illuminate to indicate a short or cut on a zone input. In order to provide line short recognition the zone
connections must have EOL resistors (see Zone Input Terminal Connections sections 2.8 to 2.10).
11.12.9 Telephone Line Monitoring - Key [10]
If the
Telephone Line Monitoring (TLM)
feature (see section 10.1) is enabled, the [10] key will
illuminate to indicate that the control panel has not detected the presence of a telephone line
for 30 seconds.
11.12.10
Fire Trouble - Key [11]
The illumination of the [11] key indicates a tamper on zone 3, if identified as a fire zone (see
"24 Hour" & Fire Zones in section 7.5).
