XFP 16 ZONE ANALOGUE ADDRESSABLE FIRE ALARM PANEL
INTENSIVE DEVICE MONITOR
This function allows you to monitor a specific addressable point to see how it responds to intensive,
repeated polls from the panel. 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. By
reporting back how many good and bad polls are made between the panel and the monitored
device, this function can help pinpoint loop wiring/communication faults and/or faulty devices.
When selected, you will be prompted to enter the loop on which the device you want to monitor is
located, the device's address and its output bit sequence:
Loop:-1 Device 1
Output bits: 0
5 6
Use the , and Accept
The output bit option allows you to monitor a device whilst it is in a particular state, for example, if
an I/O unit is reporting back faults only when it has triggered, say, a rollershutter door (e.g when its
output channel 1 is asserted), you can set the device up so it is in this state whilst being monitored.
See the table below for the output bit options available:

Caution: Note that certain channels on an I/O unit may be programmed to trigger say, a water
extinguishant system, so this function must be used with care. When you have accepted the device's
output bits sequence by pressing the Accept
the device's current analogue values, for example:

monitored is located on

(the level at which it will
flag an alarm condition)
As the device is intensively polled, some of its analogue values may change, helping to assist you in
the fault finding process. To view a running total of the number of good and bad polls between the
panel and the device at any time, press the More Information button and a window similar to the
one below will appear:
Good polls: 592, Bad polls: 3
To return to the analogue value window press the More Information button again. To exit the
INTENSIVE DEVICE MONITOR function press the Escape
