Smoke detectors are silent but communicate with sounding units
automatically to raise the alarm if smoke is detected. NB: smoke
detectors are sensitive to dust and steam so are unsuitable for dusty
areas. If a detector has raised the alarm, its red LED indicator will ash
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).
If proper maintenance is not carried out, there is a likelihood of
malfunction, including false alarms, which could disrupt operation on
site.
Smoke detectors may be identied by a reference ‘P’ on the detector
label (g.2)
Dust-resistant smoke detectors may be identied by a reference ‘DP’
on the detector label (g.3).
Note: Smoke detectors are intended for internal use in enclosed
spaces. Detectors will not function correctly if installed in open spaces
without ceilings, walls etc.
Base Station
Base stations include a buzzer, an LCD display, a navigation pad, and
if the GSM model has been selected, a modem to allow SMS
message sending. Base stations are not essential to a WES+ system,
but they provide centralised functionality and additional information
which is extremely useful on larger or complex sites.
Base Stations should be securely mounted. It is possible to use base
stations as mobile units (see Mobile Base section).
Link
Link units are used solely to relay WES+ radio messages on large or
complex sites if there is no need for additional call points. Link units
should be securely wall mounted.
Interface
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+ system.
P
WES+ units have three indicator LEDs, plus two push buttons, labelled
A and B.
All 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+ units relay all WES+ radio messages for the relevant site.
Fire Point
Fire Point units include a manual call point used to raise the alarm
when necessary and a loud alarm sounder (with optional strobe light).
Fire Points should be securely mounted approximately 1.4 metres
above the oor.
Detector - Heat
Heat detectors automatically raise the alarm if the temperature rises
above a safe level. Heat detectors are silent, but communicate with re
points and base stations to raise an audible alarm. If a detector has
raised the alarm, its red LED indicator will ash for 30 minutes or until
the alarm is reset.
Heat detectors should be securely mounted to the ceiling and regularly
maintained (see Heat Detector 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 detectors may be identied by a reference ‘A2’ on the detector
label (g.1)
