EXP-PSU

1. Introduction

The EXP-PSU is a remote power supply
intended for use in wired/wirefree alarm
systems controlled by the i-onEX range of
control units.
The power supply comprises a steel case
containing a pcb (printed circuit board) and
space for backup batteries.
The pcb holds the power supply circuits and
provides two sets of terminals for a bus
connection.
The pcb also provides a range of connectors
for outputs, plug-by communicators, and up
to 10 FSL (Fully Supervised Loop) or five
CC (Closed Circuit) zones.
The EXP-PSU provides monitoring
messages to the control unit over the
system bus. These messages include
Remote PSU Fault, Remote AC Fail, Remote
Battery Fail, and Remote Low Output
Voltage.
The EXP-PSU is designed and approved to
be used as part of a Security Grade 2 or 3
system.

About this Guide

This guide shows the simple procedure
required to physically install the EXP-PSU,
connect it to the bus, zones and outputs for
an i-onEX alarm system.
When you have completed the physical
installation please consult the i-onEX
Engineering Guide for details of providing a
bus address for the unit.

2. Before You Begin

Preparation

Before installation you should carry out a
survey of the site. You need to know how
many and what kind of detectors will be
connected to the EXP-PSU.

Siting the EXP-PSU

WARNING Ensure that the fixings are
strong enough to support the weight of the
EXP-PSU, its lid and two 17Ah lead acid
batteries. The total weight of the EXP-PSU
plus batteries can be up to 18kg.
Do site the unit:
Close to the equipment it is powering.
Upright, batteries at the bottom.
Within a protected area.
Do NOT site the unit:
In the entry or exit zones, or outside
the area covered by the alarm system.
Next to electronic equipment,
particularly computers, photocopiers or
other radio equipment, CAT 5 data lines
or industrial mains equipment.

Guided Tour

CAUTION: The printed circuit board for the
EXP-PSU has been tested for
Electromagnetic Compatibility (EMC).
However, when handling the pcb you must
take the standard precautions for handling
static sensitive devices.

Opening the Case

To gain access to the interior of the EXP-
PSU undo the screw at the bottom of the
lid. Slide the lid vertically up, then swing
the bottom of the lid out before moving the
lid down and away from the case.

WARNING: When connected to the mains
with power applied mains voltages are
present on the shrouded heads of the
terminal screws of the mains connector.
