Four pin connector can be
used for quick installation of
a Digiplex keypad or module.
Warning:
Disconnect the

Warning: Improper connection may
result in damage to the system.
Warning: During power up, the panel will
perform a module scan that lasts
between 30 and 120 seconds.
AUX POWER
Refer to transformer requirements below for Auxiliary Power Output.
Also, refer to Calculating Power Requirements (on page 42). To
connect additional wiring to auxiliary power, use the red (+) and black
(-) keypad connectors. Auxiliary power will shut down if current
exceeds 1.1A.
Transformer Requirements:
Auxiliary Supply can provide:
Usable Battery Charge Currents:
* A 40V transformer is required when selecting
the 850mA battery charge current. Using a 20VA
transformer with a battery charge current of
850mA may damage the system.
This equipment must be installed and maintained
by qualified service personnel only.
For UL and C-UL warnings, refer to the Warnings section in the Digiplex Reference and Installation Manual.

enclosure
To provide maximum lightning
protection we strongly
recommend having separate
earth connections for the dialer
and zone ground terminals.
When installing the combus wires in a noisy
environment, or when connecting the combus
across separate buildings, you must use a shielded
cable. Refer to Connecting the Combus in Noisy
Environments on page 44.
The combus supports a maximum of 95 modules.
Although external power supplies can be used to
provide power to modules connected far from the
control panel, the final modules on the combus
should not be more than 914m (30 000ft) away.
If multiple runs of wire are being used, the total
distance of all the runs combined cannot exceed
1000m (30 000ft). For example, if ten runs of wire
each measuring 304m (1000ft) were connected, the
total distance would be 3048m (10 000 ft) and
therefore exceeds the system's capacity.
