Telephone Line Connections
Connect the main dialer output to telephone company
lines using the RJ31X cables supplied.

The telephone line inputs have overvoltage
protection in accordance with UL1459, as
specified in UL985/UL1023.
The system is shipped defaulted for Contact ID
format. It is the only format capable of uniquely
reporting all 86 zones, as well as openings and
closings for all 75 users. This requires central
stations to be equipped with the 685 receiver
using software level 4.10 or higher. If you need
an update, contact your distributor.
To prevent the risk of shock, disconnect
phone lines at the telco jack before servicing.
If the communicator is connected to a PABX,
be sure it has a backup power suppl
that can
support the PABX for 24 hours (central
station) or 60 hours (remote station). Many
PABXs are
not
power-backed up, and this can
result in a communication failure if power is
lost
.
Reporting Formats
The system supports the following formats:
ADEMCO Low Speed 3+1; 4+1; 4+2; Sescoa/Radionics
3+1; 4+1; 4+2; ADEMCO 4+2 Express; ADEMCO High
Speed; ADEMCO Contact ID

Figure 3-8: Telephone Line Connections
Wiring Burglary, Panic, and Smoke Detector Devices to Zones 1-9
The maximum zone resistance is 100 ohms for
zones 1 and 8, and 300 ohms for all other
zones (excluding the 2K EOL resistor).
To wire burglary and panic devices to zones 1-9, connect
sensors/contacts to the hardwire zone terminals (10
through 23). See Figure 3-9. 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.
