3-11
Dialer Operation
When only the main dialer is enabled (field 3
✳30 = 1,0), the system attempts to route all messages over the main dialer
output.
When both the main and backup dialers are enabled (field 3*30 = 1,1), the panel will Alternate
Dialers by pairs (make two attempts to report on the Main Dialer, then make two attempts to report on the
Back Up dialer). The panel will continue to do this to the Primary Phone number until it reaches its
programmed attempts in 3*21, then it will do the same to the Secondary phone number. Test Report is
always sent on Alternating dialers.
The communicator makes up to 8 attempts to transmit the messages to one or both telephone numbers (primary and
secondary), depending on the report routing options programmed. After the 8
th
attempt, the communicator hangs up and
the system displays “COMM FAIL” on the keypad. The number of dialer attempts are programmed in field 3
✳21 (default
= 8; must be restricted to 3, 4, or 5 if a secondary phone number is programmed).
Wiring Burglary and Panic Devices to Zones 1-8
The maximum zone resistance is 100 ohms for zones 1, 2 and 8, and 300 ohms for all other zones (excluding the
2K EOL resistor).
To wire burglary and panic devices to zones 1-8, connect sensors/contacts to the hardwire zone terminals (15 through
27). Connect N.C. and N.O. devices as follows:
• Connect N.C. devices in series with the high (+) side of the loop. The 2K EOL resistor must be connected in series
with the devices, following the last device.
• Connect N.O. devices in parallel (across) the loop. The 2K EOL resistor must be connected across the loop wires
at the last device.
Using 2-Wire Smoke Detectors on Zones 1 and 2
Zone 1 and 2 can support up to 16 2-wire smoke detectors each (32 total).
The alarm current on zones 1 and 2 supports only one smoke detector in the alarmed state.
When assigned zone type 9 or 16, the second entry of a User Code + off at a keypad interrupts power to these zones to
allow detectors to be reset following an alarm.
