4) Comms Fault (R1 NO / R COM) Relay 1
is programmed as a communications
fault relay. If there is no communication
path available for longer than the pre
programmed time this will remain active until
communications are restored.
Note: This
relay can be programmed to be remotely
activated for remote arm/disarm or other
access control functions. Each relay can

Refer to programming option 38.
5) Tamper (TAMPER) Optional. Connect to
the alarm panel tamper zone or similar. This
circuit requires a normally closed tamper (no
EOLR required). If not used, simply leave the
shunt on the connector.
6) PSTN Optional. Connects to standard PSTN
(RJ12 Mode 3, 4-wire).
7) Alarm Panel (PANEL) Connects to the
“PSTN” connection on the alarm panel
using a RJ12 (Mode 3, 4-Wire) cable. This
port can support any alarm system that
communicates using the Contact ID format.

1) 12V DC >300mA (+12V and GND) connect
to a 12V supply capable of supplying at
least 300mA.
2) Zone Inputs (Z1 / Z2 / Z3 / Z4) Each zone
requires a Series End of Line Resistor to be
‘sealed’. Zones 1 and 2 require 3K3. Zones 3
and 4 require 6K8. Refer to Wiring Diagram
on page 3.
All zones operate as 24hour
alarm inputs. Zones 1 and 2 are enabled
by default. Zones 3 and 4 are disabled by
default. Refer to Option 30 to change.
3) Zone / Power / Battery / Tamper Fault (R2
NO / R COM) Relay 2 is programmed as an
alarm output. This will activate when an
alarm condition is active on the 4 Plus (Zone,
Power Fault, Tamper active).
This relay can
be programmed to be remotely activated
for remote arm/disarm or other access
control functions. Each relay can also have
