Indicators on the PCB
Run This LED indicates that the micro-controller is operating and must always be flickering.
Dial This LED, located adjacent to the dial relay, will light when the dialler is in its reporting
sequence (line looped) and will extinguish when reporting is completed.
PGM This LED indicates when the PGM output is active for an event as
per the programming of Function 80
INT, EXT & AUX
These LEDs indicate there is power available on respective outputs, when
one of these LEDs are out, there may be a short on the relevant output
Initialization - FACTORY DEFAULT
There are 3 ways to initialize the panel to factory defaults
1. Enter program mode and use Function 90
2. Power the panel up with any button pressed on the keyboard for 3 seconds.
3. Power the panel up with the default pins shorted on the PCB (do not leave link across default pins)
On Power up
On power up the unit performs an internal self test of its EEPROM and then boots with this program. If the
EEPROM is found to have been corrupted in some way then the factory defaults will be reloaded indicated by 5
beeps from the keypad.
If the EEPROM is correct then the panel will power up in the mode determined by Function 98
(Status on power up).
If Function 98 is 0 (Do not retain the On /Off status) the unit starts off in OFF mode and the sirens may operate
for half a second.
If Function 98 is 1 (Retain On/Off status) and the unit was armed when power was interrupted, then when power
is restored, the unit will allow a settling time of 60 secs and attempt to re-arm. Sectors unsealed after the settling
time will be automatically isolated and will be reported as such. After the 60 seconds settling time the unit will dial
through a mains fail restore, a low battery restore and the current status of the panel with user code 31.
Dialling sequence
The dialling sequence from start to finish consists of 6 dialling attempts.
The first 3 dialling attempts to the first phone number (with a 20 second pause waiting for handshake) before
dialling next attempt.
If after the 3 attempts no handshake is received then the dialler will release the line for 5 minutes.
The dialler will then make 3 attempts to the second phone number (if no second number has been programmed
then the first number will be tried again).
If after these 3 attempts handshake is still not received the dialler will hang up until another condition causes it to
dial, at which time the previous condition will also be reported. The PGM output will trigger if Function 80 option
5 is selected.
The STATUS LED on the keypad will turn on during the sequence until it has completed,
this includes during the 5 minute wait period.
