Trouble Conditions
Initiating Device Circuits
A decrease of current to approximately 3.3 mA or programming the zone as disabled on any initiating device circuit will result in
the following:
1. Activation of trouble relay contacts and local buzzer.
2. Operation of any output circuits which have been described as TROUBLE BELL.
3. "TROUBLE" and <CIRCUIT> displayed on LCD.
4. Activation of the amber TROUBLE LED in a flashing mode as well as corresponding zone. NOTE: The TROUBLE LED
will continue to flash until all events in the TROUBLE queue are viewed. This is accomplished by scrolling through all of
the events by use of the scroll up and scroll down buttons. The LED will go steady after all trouble events have been viewed.
5. Activation of red ALARM indicator on LED display.
6. Activation of red OUTPUT indicator(s) on LED display module for the output circuit(s) which are mapped to the
initiating device circuit(s).
NOTE: When the circuits are operated in the Class A mode any trouble condition will require manual operation of the Reset
switch to restore the panel to normal after the fault has been removed.
A complete loss of power will result in the transfer of the common system trouble relay contacts.
If Zone 1 is programmed as Firecycle, an increase in current to 10 mA or greater will result in the above.
Notification Appliance/Releasing Circuits
An increase of current to approximately 0.63 mA or a decrease in current to approximately 0.11 mA on any output circuit or
connecting an indicating appliance backwards, or disabling an output will result in the following:
1. Activation of trouble relay contacts and local buzzer.
2. Operation of any output circuits which have been programmed as TROUBLE BELL. If this output is in trouble, a
TROUBLE BELL on this output may not function correctly, depending on the type of trouble.
3. "TROUBLE" and "OUTPUT #" <CIRCUIT NO.> displayed on LCD.
4. Activation of yellow Output indicator(s) on LED display for the notification appliance(s)
5. Activations of yellow SYSTEM TROUBLE indicator on LED display.
6. Activation of yellow OUTPUT indicator(s) on LED display of any output circuits(s) which have been describes as
TROUBLE BELL.
NOTE: A current in excess of 1.4 Amps, when the panel is in alarm condition, will result in that output being disables and a trouble
as described above.
A problem in an audible or visual device may not be apparent when the panel is in a normal condition. If the circuit indicates a
trouble condition when the panel is in an alarm condition the problem must be located and corrected.
Earth Fault
A short between any circuit and earth ground will result in the following:
1. Activation of trouble relay contacts, trouble and EARTH FAULT LEDs in a flashing mode, and local buzzer.
2. Operation of any output circuits which have been described as TROUBLE BELL.
3. "TROUBLE" and "GROUND" displayed on LCD.
Loss Or Reduction Of Power On
A reduction in the AC input voltage will result in the following:
1. Trouble LED and local buzzer will sound 1½ hour delay of trouble relay.
2. Operation of any output circuits which have been described as TROUBLE BELL.
3. "TROUBLE" and "A.C." displayed on LCD.
4. LCD Backlight will be extinguished.
5. Green Power On indicator on LED display will be extinguished.
6. Activation of yellow POWER TROUBLE indicator on LED display.
7. Activation of yellow SYSTEM TROUBLE indicator on LED display.
8. Activation of yellow OUTPUT indicator(s) on LED display of any output circuit(s) which have been described as
TROUBLE BELL.
