Raising the Alarm
Manual activation
To raise the alarm, press any call point in the system. The call point will
latch into the pressed position and a mechanical yellow and black
striped ag will be displayed in the call point window as below.
Automatic activation
Smoke Sensors will automatically raise the alarm if sufcient smoke
is detected. Heat Sensors will automatically raise the alarm if the
temperature rises above the threshold. The red ‘Alarm’ LED will only
ash on the unit(s) which raised the alarm.
Silencing the Alarm
Note: it is vital to conrm that there is no site incident before silencing
the alarm.
Do not attempt to open the unit or deactivate by removing the battery.
The alarm must be silenced either by using the reset key or at the
Emergency Control Unit.
The alarm will automatically silence 30 minutes after activation.
The alarm can be manually cancelled from an Emergency Call Point
that has been pressed using the reset key provided. If necessary, a call
point on a nearer emergency call point can be pressed and then reset
to cancel the alarm. Please wait for 5 seconds between pressing and
resetting a call point.
After the alarm has cleared the system has a short (2 minute) re-arm
period during which the sirens will sound intermittently, and the amber
warning LEDs ash in groups of 5, following which the system is
re-armed and ready for use.
During the re-arm period, the alarm cannot be reactivated. It is
therefore vital to conrm that there is no re hazard before silencing
the alarm.
Resetting a Call Point
Any Emergency Call Point that has been activated will periodically
beep after the re-arm period has ended as a reminder that the unit
needs to be mechanically reset using the key before they can be used
to raise a alarm.
The Latched alert is displayed on the Emergency control Unit and will
show which individual Emergency Control Unit needs to be reset:
SYSTEM WARNINGS
23/06 22:13 004F LAT
1) Insert reset key with tab to the right as shown below.
2) Push key in as far as possible
3) Turn key anti-clockwise until a loud mechanical click is heard.
4) Remove the key
Ensure the call point is fully reset before removing the key. Partially
resetting a latched call point after the re alarm has been cancelled
can retrigger the re alarm.
