LST700 SERIES FIRE ALARM PANEL
Two levels of control are available to the User(s) of this fire alarm panel - General User and Authorised User.
1. General User Controls (access level one)
When the panel is in access level one, the indicator lights on the front of the enclosure give a
comprehensive overview of the system’s current status. Any fire and fault conditions are clearly
displayed, disablements highlighted and the status of all outputs reported. For detailed descrip-
tions of what each indicator means, please refer to the table on the opposite page.
The only functions that can be performed by the user when the panel is in access level one are:-
■ Muting the panel’s internal sounder by pressing the Silence Internal Sounder button;
■ Overriding any delays which may have been programmed into the panel by pressing the
Silence / Activate Sounders button (only applicable when the panel is in alarm); or
■ Putting the panel into access level two (the Authorised User state) - see below.
2. Authorised User Controls (access level two)
To avoid unauthorised changes to critical parts of the fire alarm system, controls such as silencing
the sounders, resetting an alarm condition and implementing disablements are only accessible via
a secure method of entry which puts the panel into access level two.
To put the panel into access level two:-
Turn the key to the I position (
please note the key cannot be removed when in this position). When
the key is in the I position, the Accessed light will be lit steady to show the user that the controls are
operative. To leave the access level two, turn the key back to the O position
Details of how to use the Authorised User controls can be found on pages 8 to 11 of this User Manual.
