LST700 SERIES FIRE ALARM PANEL
When the fire alarm panel receives an alarm trigger from a detector or manual call point located in a
zone that is not already in a fire state, it will:-
■ Flash the general fire and appropriate fire zone light(s) on the front of its enclosure.
■ Sound its internal sounder.
■ Start the alarm sounders and outputs including, if enabled, the remote output
(
provided there are no delays applicable to the zone which is in alarm).
At this point the building’s fire management plan should be executed.
Important Note: Zones which have been disabled cannot be triggered into an alarm
condition (see page 10 for further information on disablements).
Silencing the alarm sounders
■ The alarm sounders may be silenced by putting the panel into access level two and
momentarily pressing the Silence / Activate Sounders button .
The alarm sounders and the panel’s internal sounder will cease to sound and the light(s) for the
zone(s) in alarm and the red general fire light will be lit steady. All other alarm outputs (i.e. the
remote and auxiliary fire outputs) will remain asserted.
New zone In alarm
Should a new zone be triggered into alarm whilst the alarm sounders are silenced, the panel will:-
■ Automatically reactivate the alarm sounders
■ Flash the general fire and appropriate fire zone light(s) for any new zone(s) in alarm
■ Keep the light(s) for the previous zone(s) in fire lit steady
Manually activating the alarm sounders (i.e to evacuate the building)
■ Momentarily pressing the Silence / Activate Sounders button when the panel is in access
level two (see page 6) will cause the alarm sounders to sound. Note: The panel’s remote and
auxiliary fire outputs
will not be triggered when the building is manually evacuated in this way.
Pressing the Silence / Activate Sounders button again will silence the alarm sounders.
NB: If the sounders have been disabled, pressing the Silence/Activate Sounders button will have no effect.
Resetting the panel
■ After the cause of the alarm has been investigated and cleared and the alarm sounders have
been silenced, the panel can be reset by pressing the Control Panel Reset button .
Fire alarm systems which are directly monitored by a Fire Brigade may only be reset and silenced
by the Fire Service personnel attending an alarm. Users who interfere with monitored systems
which are in alarm may be subject to heavy fines.
The Panel will give a double beep to indicate the reset process has started and, after a few
seconds, the zone fire and general fire lights will go out to indicate the process is complete. If
there are still alarm triggers on any zone the panel will go back into alarm as before.
Exitting access level two
To exit access level two at any time, press the Exit Access Mode button (or, on the keywsitch
version of the panel, turn the key back to the O position).
