previous bypass status will be re-established. This eliminates the need to re-enter the bypass entries every time the system is
armed. If a user is in the process of entering new bypass entries on the keypad, pressing the
[
BYP
] key will override new
information and reinstate previous bypass entries.
11.11 Keypad Chime Zones (on LED Keypads)
A chimed zone advises you when a zone is opened by creating a rapid intermittent beep tone (beep-beep-beep-beep-beep). Up
to six zones plus the local keypad zone can be programmed as chime zones. To turn on the chime zone feature, press and hold
the key corresponding to the desired zone (
[1] to [6] ) for three seconds until the intermittent chime beep is heard. This means
that the chime feature has been activated. If a continuous beep is heard, this means that the chime beep has been deactivated.
To enable the chime feature on the keypad zone, press and hold the
[8] key for three seconds. To mute the keypad's alarm
sounder, press and hold the [9] key for three seconds until the intermittent chime beep is heard. This means that the muting
feature has been activated. If a continuous beep is heard, this means that the muting feature has been deactivated. If there is
more than one keypad in the system, you must program each keypad’s chime zones separately. Keypad chimes must be
reprogrammed if the panel suffers a total power loss.
Key [1] - [6] : Turns chime ON or OFF in zones numbered 1-6
Key [8] : Turns chime ON and OFF for the local keypad zone
Key [9] : Turns the keypad's alarm sounder muting ON or OFF
11.12 Trouble Display Monitoring
Trouble conditions are continuously monitored by the control panel, which recognizes and displays 10 different trouble conditions
on the keypad. When a trouble condition occurs, the
[
TBL
]/[
TRBL
] key will illuminate and the keypad will emit an intermittent beep
if the Audible Trouble Warning (see page 39) is enabled. Press the [
TBL
]/[
TRBL
] key to switch to trouble display mode. The [
TBL
]/
[
TRBL
] key will flash and any illuminated keys correspond to a current trouble condition as described below. Press any key to exit
the trouble display mode.
11.12.1 No Battery/Low Battery - Key [1]
The control panel conducts a dynamic battery test under load every 60 seconds. The illumination of the [1] key
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. If the control panel is currently running on battery power, the illumination of the
[1]
key indicates that the battery voltage has dropped to 10.5 volts or lower.
11.12.2 Power Failure - Key [2]
The control panel will detect a power loss if a continuous loss of AC (less than or equal to 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 page 24), the panel will transmit the report code programmed at address 499 and the
[
TBL
]/[
TRBL
] key
will flash rapidly indicating a power failure. The trouble indicator is restored if AC is detected during the dynamic battery test
and the panel will then transmit the report code programmed at address 507. You can remove the power failure trouble
indicator from the trouble display by enabling the Exclude Power Failure From Trouble Display option (see page 39).
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
9
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 shut down 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 650mA (728 Ultra) or 700mA (738
Ultra). This will cause an 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 while attempting to communicate with the monitoring station computer or the
Espload software, the
[7] key will illuminate. This trouble is automatically cleared when the [
TBL
]/[
TRBL
] key is pressed
and the user has exited from the Trouble Display.
