maintained (see Heat Detector Maintenance section) and installed in
line with current local legislation. If proper maintenance is not carried
out, there is a likelihood of malfunction, including false alarms, which
could disrupt operation on site.
Heat Detectors are intended for internal use in enclosed spaces.
Detectors will not function correctly if installed in open spaces without
ceilings, walls etc.
Smoke Detectors
WES

Smoke Detectors are silent but communicate with sounding
units automatically to raise the alarm if smoke is detected.
All Smoke Detectors are sensitive to dust and steam - use the WES
3
Smoke Detector in dusty areas, or a WES
3
Heat Detector in areas
exposed to excessive levels of dust or steam. If a detector has raised
the alarm, its red LED indicator will flash for 30 minutes or until the
alarm is reset.

Smoke Detectors should be securely mounted to the ceiling and
should be regularly maintained (see Smoke Detector Maintenance
section) and installed in line with current local legislation. If proper
maintenance is not carried out, there is a likelihood of malfunction,
including false alarms, which could disrupt operation on site. Smoke
Detectors are intended for internal use in enclosed spaces. Detectors
will not function correctly if installed in open spaces without ceilings,
walls etc.
Link
WES

Link units are used solely to relay WES
3
radio messages on
large or complex sites if there is no need for additional Fire Points. Link
units should be securely wall mounted.
Interface
WES

Interface units allow input or output devices to be connected to
or via the WES3 network. They can also take an input from an external
trigger and set off the alarm on the WES
3
system.
System Overview
All WES
3
units have three indicator LEDs, plus two push buttons,
labelled A and B. Some units have additional buttons and features.
At least one CONNECT unit or Base Station needs to be included in a
WES
3
network as they configure the WES
3
network.
Units should be securely fixed using the two integrated mounting
points. We recommend that you use M4 x 50mm pan head screws
and wall plugs or other fixings suitable for the particular wall/ceiling
material.
The tamper switch on the rear of each unit must be in contact with the
wall or ceiling for the unit to function correctly.
All WES
3
units relay all WES
3
radio messages for the relevant site.
CONNECT
WES CONNECT includes a alphanumeric key pad, colour LCD display
and a 4G GSM module to include a 4G-enabled sim card.
CONNECT units can be used as mobile units (see Mobile Base
section).
Base Station
WES
3
Base Stations include a buzzer, an LCD display, a navigation
pad, and if the 3G GSM model has been selected, a modem to allow
SMS message sending.
Base Stations can be used as mobile units (see Mobile Base section).
Call Point
WES
3
Fire Point units include a manual call point used to raise the fire
alarm when necessary, a first aid button to raise an alert for medical
assistance, and a loud alarm sounder (with optional strobe light).
Fire Points should be securely mounted approximately 1.4 metres
above the floor, or in accordance with specific client- or site-
requirements.
Heat Detectors
WES

Heat Detectors automatically raise the alarm if the temperature
rises above a safe level. Heat Detectors are silent, but communicate
with Fire Points and Base Stations to raise an audible alarm. If a
detector has raised the alarm, its red LED indicator will flash for 30
minutes or until the alarm is reset.
Heat Detectors should be securely mounted to the ceiling and regularly
