Smoke Sensors
WES
3
Smoke Sensors are silent but communicate with sounding units
automatically to raise the alarm if smoke is detected. There are two
Smoke Sensors in the WES
3
range; a Standard Smoke Sensor and a
Dust Resistant Smoke Sensor.
All Smoke Sensors are sensitive to dust and steam - use the WES
3
Dust Resistant Smoke Sensor in dusty areas, or a WES
3
Heat Sensor
in areas exposed to excessive levels of dust or steam. If a sensor has
raised the alarm, its red LED indicator will ash for 30 minutes or until
the alarm is reset.
WES
3
Smoke Sensors should be securely mounted to the ceiling and
should be regularly maintained (see Smoke Sensor Maintenance
section). If proper maintenance is not carried out, there is a likelihood
of malfunction, including false alarms, which could disrupt operation on
site. Smoke Sensors are intended for internal use in enclosed spaces.
Sensors will not function correctly if installed in open spaces without
ceilings, walls etc.
Emergency Control Unit (ECU)
WES
3
Emergency Control Units include a buzzer, an LCD display and
a navigation pad. An Emergency Control Unit is required to congure
the WES
3
network, and therefore at least one WES
3
Emergency
Control Unit needs to be included in a WES
3
network.
It is possible to use Emergency Control Units as mobile units (see
Mobile ECU section).
Link
WES
3
Link units are used solely to relay WES
3
radio messages on
large or complex sites if there is no need for additional Emergency Call
Points. Link units should be securely wall mounted.
Interface
WES
3
Interface units allow external outputs to be triggered in the event
of an alarm. They can also take an input from an external trigger and
set off the alarm on the WES
3
system.
WES
3
Units
All WES
3
units have three indicator LEDs, plus two push buttons,
labelled A and B.
Units should be securely xed using the two integrated mounting
points. We recommend that you use M4 x 50mm pan head screws
and wall plugs or other xings 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.
Emergency Call Point (ECP)
WES
3
Emergency Call Points (ECPs) include a manual call point used
to raise the alarm when necessary, a rst aid button to raise an alert for
medical assistance, and a loud alarm sounder (with optional strobe).
Emergency Call Points should be securely mounted approximately 1.4
metres above the oor, or in accordance with specic client- or site-
requirements.
Heat Sensor
WES
3
Heat Sensors automatically raise the alarm if the temperature
rises above a safe level. Heat Sensors are silent, but communicate
with Emergency Call Points and Emergency Control Units to raise an
audible alarm. If a sensor has raised the alarm, its red LED indicator
will ash for 30 minutes or until the alarm is reset.
Heat Sensors should be securely mounted to the ceiling and regularly
maintained (see Heat Sensor Maintenance section). If proper
maintenance is not carried out, there is a likelihood of malfunction,
including false alarms, which could disrupt operation on site.
Heat Sensors are intended for internal use in enclosed spaces.
Sensors will not function correctly if installed in open spaces without
ceilings, walls etc.
