For instructions on the new
compatible Mains Powered
Interface Unit S4-78302-02NM see
leaflet supplied with the product.
Old Mains powered
interface unit
This interface unit operates from mains power and incorporates
its own battery-backed power supply. It has 4 channels, each
may be configured as input or output and are configured as
conventional zone and sector circuits respectively.

Colour Grey and Black
Number of
channels 4 channels, (each configurable
as input or output)
Batteries 2 - 12V 2.1Ah sealed lead acid
batteries
Input (zone)
channels 2-wire inputs for conventional
zone circuits. Circuits are
monitored for:
¨
Detector fire
¨
MCP fire
¨
Wiring open circuit fault
¨
Wiring short circuit fault
Monitoring conforms to BS5839
by detecting a MCP activation if
a detector is removed providing
detector heads are fitted to
diode bases.
Maximum detector load: 2mA.
An end-of-line capacitor/diode
(supplied) must be used.
The input circuits may be
configured to operate with
various manufacturers
detectors and MCP's: Gent,
Apollo, Hochiki, Menvier, Nittan,
Notifier and Thorn
On certain sites where older
type detectors and MCPs are
used that give a short circuit
fire, set the rotary switch to
position ‘F’.
Output (sector)
channels Output (sector) channel will
operate conventional equipment
such as sounders / bells and
door holders.
A maximum current of 500mA is
allowed and can be shared
between the output channels
(each fused at 800 mA).
Sectors are monitored for:
¨
wiring open circuit fault
¨
wiring short circuit fault
End-of-line 22K resistor
(supplied) must be used.
Optional up to 4 Octal relays
with diode packs may be fitted
within the enclosure. These
provide DPCO voltage-free
contacts rated at
10 amps, 240 Vac, resistive
load.
