devices that are present, or to identify where a break may be. See
Scanning for MX Devices page 8-6.
From MX Loop Status display press IR CTRLF1 to access the IR
(Infrared) commands.
This command requires operator Access Level 2.
The 850 detectors support infrared (IR) communication with the 850EMT
MX service tool. This allows technicians to carry out functions such as
programming the detector’s device number, reading its parameters and
status, using an IR connection while standing some distance from the
detector.
Before you can communicate with a detector using IR the loop the
detector is connected to must be put into IR mode. Select the required
MX loop (see Figure 8-5) and then press IR CTRLF1. This will show
the IR controls – see Figure 8-6a.
Fig 8-6a –

Loop IR
Pressing IR ONF1 will activate IR mode on the currently displayed
loop.
Pressing IR OFFF1 will deactivate IR mode on the displayed loop.
Pressing All ONF2 will turn on IR mode on all loops.
Pressing All OFFF3 will turn off IR mode on all loops.
Pressing << BACK F1 will return to the previous display (Figure 8-5).
IR mode automatically times out after 8 hours if it is not
turned off via the menu.
A detector in IR mode cannot communicate with both the
panel and the 850EMT service tool at the same time.
Therefore while a detector is communicating with the service
tool it is ‘off line’ and can no longer send alarms to the MX1.
After 1 minute the detector will go into Device-fail at the MX1.
The DEVICESF4 command on the MX Loop Status screen can be
used to scan that MX Loop for all MX devices present – even if the MX1
has no, or a different, datafile present.
This can be used, for example, at installation time to check all devices
have been installed, wired and addressed correctly, even without any
datafile having been programmed into the MX1.
