XFP 16 ZONE ANALOGUE ADDRESSABLE FIRE ALARM PANEL
LOOP TEST
This function helps pinpoint loop wiring/communication faults by continually polling all loop
addresses for a specified number of times and reporting back how many good and bad polls there
have been on an address by address basis. In order to do this, the panel suspends all other system
activity when this test is taking place - fires, etc, will not be flagged so please use this function with
care. When selected, you will be prompted to enter the loop you wish to monitor and how many
times you want the panel to poll each device (1 to 255).
Loop:-1
Number of polls for each device:25
5 6
Use the , and Accept
required. The test will begin and a test status window will appear, showing the address currently
being polled together with a running total of the number of good and bad polls. Polling takes place
on an address by address basis in numerical order and will take several minutes.
Loop:1 Device 1: Results
Good polls:25 Bad Polls:0
When the test is complete, the results will appear in a new window, similar to the one below.
Loop:1 Device 1:Results
Good Polls:128 Bad Polls:3

Pressing the Escape
A number of bad polls in a particular section of the system indicates a problem area for investigation,
e.g. voltage drop, bad connection, etc.
To assert output channels 1 and 3 of the device being viewed, press the More Information button.
You will be presented with a window similar to the one below:
Loop:1 Device: 1
Turn ON output channels 1&3
In the case of detectors and manual call points, activating channels 1 and 3 will turn their LEDs on.
Caution: note that channels 1 and 3 on an I/O unit may be programmed to trigger say, a water
extinguishant system, so this function must be used with care.
Activating channels 1 and 3 on a sounder/beacon will have no effect.
If you are happy to proceed, press the Accept
device. Once activated, you will be given the option to switch off output channels 1 and 3 by pressing
4
the Accept button again.

Press the Escape button as appropriate to return to the previous menus.
DISPLAY DATABASE
This function allows you to view the panel's database of loop devices. Available on a loop by loop basis,
the information displayed includes the device's type, address and description (zone and device text).
When the DISPLAY DATABASE? prompt is accepted, you will be prompted to enter the loop you wish
to view the database of:
