Where detector bases have been installed without the detector head and the detection loop wiring integrity is
maintained, a processor restart can be applied to add or remove devices from the system. This procedure
negates the requirement to power down the control panel and can also be used when changing device types.
The control panel will display appropriate fault conditions as the devices are added or removed from the
detection loop wiring. To apply a processor restart the internal buttons MUST be operated in the following order.

!

 

Fit, remove or change the device(s) located in the detector base(s).

!

 

Press the processor restart button (SW1) located on the MBLC card, part number 44782-K073.

!

 

Press the processor restart button (SW1) followed by the processor Reset button (SW2) located on the
MCP card, part number 44782-K071.

!

 

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)

Note: A processor restart will request all detection loops to begin logging the attached detectors.

The auto learn facility is available through the Set menu structure (Refer Table 8) and saves considerable time
when installing a system as it allows the user to specify the loop to be logged. It is recommended that the auto
learn option is only used where detector bases are pre-installed without the detector head and the detection
loop wiring integrity is maintained.

!

 

Fit, remove or change the device(s) located in the detector base(s).

!

 

Select the Auto Learn menu option Set→Loop config→Autolearn. (Refer to Table 8)

!

 

Enter the loop to be re-learned.

!

 

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)

With the control panel switched off to prevent accidental damage. Use an Ohmmeter to re-check the external
sounder circuit wiring to the control panel.

!

 

Transfer the end-of line resistor to the last device on each sounder circuit output.

!

 

From within the panel, check that all sounder circuits have a 10K resistance between the cable pairs
and that each cable has a reading greater than 20M ohm with respect to the panel earth stud.

Connect the sounder circuit cable to the sounder circuit terminals and power up the control panel.

For each sounder circuit carry out the following procedures:

!

 

Ensure that no sounder outputs are energised. Apply a short-circuit condition to one of the sounder
circuits and ensure that the COMMON FAULT and the SOUNDER FAULT status light comes on, a
SYSTEM FAULT is indicated on the LCD display and the internal buzzer operates pulsed.

!

 

Clear the fault condition and check that the panel reverts to the normal operating condition i.e. the
POWER ON status light is on and the display reads STATUS NORMAL.

!

 

Apply an open circuit condition to a sounder circuit and ensure that the COMMON FAULT and the
SOUNDER FAULT status light comes on, a SYSTEM FAULT is indicated on the LCD display and the
internal buzzer operates pulsed. Clear the fault condition and check that the panel reverts to normal
operation.

To check the operation of the sounder circuits enter the password and press the manual EVACUATE button
located on the panel Front Panel Display. The audibility level of the sounders should be checked to ensure that
they conform to relevant standard or national codes and to the customer’s satisfaction. Check that ALL sounder
devices are operating correctly. Press SILENCE BUZZER, SILENCE ALARM and RESET buttons to return the
system to STATUS NORMAL.

The system should now be clear of fault conditions and ready to configure site-specific zone & device text
messages and cause & effect strategy programming to complete the installation.
