POWERING DOWN
To switch the control panel off always disconnect the batteries first followed by the mains ac supply.
10.4
CONNECTING THE DETECTION LOOP
With the control panel switched off to prevent accidental damage. Use an Ohmmeter to re-check the external
detection loop wiring to the control panel.
detection loop wiring to the control panel.
!
Check for continuity of the feed and return of the +ve and -ve legs of each detection loop.
!
Check that the +ve and -ve legs of each loop has a reading greater than 20M ohm with respect to the
panel earth stud.

Remove the wire links from the loop 1 terminals on the terminal board and insert the loop connections observing
the polarity (+ and -).

Power up the control panel (refer 10.2) remembering to apply the mains ac supply first.
The system will perform a number of calibration diagnostic routines, which can be viewed on the display. Each
detector address is checked to determine the device type. If more than one device is located at the same
address, or the type code is invalid a fault will be indicated on the display after the logging on process has
finished. Do not press any panel buttons during the logging on process. Upon completion check the following:

The panel will indicate a SYSTEM FAULT - ‘BLC 1 Loop 01 logon flt’ due to the newly added
device(s). Clear the fault using the ‘accept logon count’ menu option located at Set→Loop
config→Accept logon count. (Refer to Table 8) Select ‘Yes’ to accept revised logon count.

Check that the panel reverts to normal condition and the POWER ON status light is on and the display
reads STATUS NORMAL.
reads STATUS NORMAL.

Check no other faults are present at this stage and if faults exist on the detection loop they will require
clearing before continuing.

Check that all devices attached to the detection loop are being monitored by the control panel. Use the
list loop device menu option to view the device attached. (Refer to Table 7)

Check the loop listings against installation drawings or programming sheets etc.
Repeat the above procedure for further detection loops to be connected to the control panel.

ADDING OR REMOVING LOOP DEVICES
Detection loop devices can be added or removed from the control panels memory using one of the following
procedures. The procedure used depends mainly upon the criteria for the work involved when adding or
removing the device(s) from the system.
procedures. The procedure used depends mainly upon the criteria for the work involved when adding or
removing the device(s) from the system.
Note: The detector manufacturers recommend that devices should be powered up for a minimum of 5 minutes
to enable optimum operational temperatures to be reached and calibration routines completed before the control
panel takes the returned data as valid information.

10.5.1 Power
Down
Where the installation loop cabling has to be broken or disconnected at the device base, and to reduce noise
induced within the signalling loop cable, which may cause unwanted false alarms, the preferred method is to
power down the control panel using the following procedure:
induced within the signalling loop cable, which may cause unwanted false alarms, the preferred method is to
power down the control panel using the following procedure:
!
Power down the control panel before work commences – remember batteries first followed by mains.
!
Make the modifications to the detection loop cabling as required.
!
Fit or remove any new devices and bases.
!
Power up the control panel – mains first.
!
Wait until the panel has re-calibrated the loop count.
!
Accept the revised logon count as described in the previous section. (Refer to Table 8)
This procedure is also recommended when adding or removing break glass call points or interface modules to
the detection loop.
