LPCB APPROVED CFP ALARMSENSE 2/4/8 ZONE FIRE ALARM PANEL
PROGRAMMING THE PANEL
An overview of the panel's controls
Three control levels are available on the panel - general user (access level 1), authorised user (access level 2) and
engineer (access level 3), as detailed below:
General user controls (access level 1)
When the panel is in its normal state, the indicator lights on the panel front 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. The only functions that can be performed when the panel is in this state are:
•
Muting the panel's internal sounder.
•
Overriding any delays which may have been programmed into the panel.
•
Putting the panel into access level 2 to access the authorised user controls (see below).
Authorised user controls (access level 2)
To avoid unauthorised changes to critical parts of the fire alarm system, certain fire alarm panel controls are only
available to authorised users. These include:
•
Silencing the sounders.
•
Resetting an alarm condition.
•
Manually activating the alarm sounders (to evacuate a building)
•
Testing the indicator lights.
•
Disabling or enabling any (or all) of the following: zones, sounders, the fault output, the remote output, the
auxiliary fire output and delays.
The authorised user controls can be accessed by entering the code 2 1 4 3 using the keypad or, by turning the
keyswitch to the 'I' position.
For detailed information on how to use the general and authorised user controls, please refer to the User Manual
/ Log Book.
Engineer controls (access level 3)
It is possible to read or interrogate the site specific data at this level. The following controls are available to
competent service personnel only:
•
The programming of coincidence / double knock. Note: This function is non-compliant with EN54-2.
•
The setting-up zones for non-latching operation. Note: This function is non-compliant with EN54-2.
•
The programming of delays.
•
The invoking of test procedures.
•
Programming silenced sounders to resound, or not resound, when new zone in alarm.
•
Fault diagnosis.
A brief overview of these functions appears below. Details of how to gain access to the engineer controls and how
to use them appears on pages 16 and 17. We recommend, however, that you carefully read the sections below
before attempting to implement any changes to the factory defaults or existing system set-up.
Engineer functions
Coincidence (Note: This function is non-compliant with EN54-2)
The programming of coincidence (also referred to as 'double knock') is a feature often used on sites where
the consequence of a false alarm can be onerous, e.g. where the panel is used to trigger a sprinkler, or gas
extinguishant system.
Coincidence is programmed into the panel in pairs of zones, the pairs being zones 1 and 2; zones 3 and 4 (if fitted),
zones 5 and 6 (if fitted); and zones 7 and 8 (if fitted).
When any of these pairs are programmed to operate in coincidence mode, there must be alarms on both zones
before the sounders and outputs are turned on. If only one of the pair goes into alarm, the panel will indicate the
alarm condition by illuminating the relevant indicator on the front panel and sounding its internal sounder, thus
prompting a responsible person to investigate.
If found to be false, the alarm can be reset by the user. If found to be a true fire condition, the user can manually
activate the alarm sounders and outputs by entering access level 2 and pressing the SILENCE/RESOUND SOUNDERS
button.
