2.5 Device Information Tab
2.5.1 Device
Type
This function is for display purposes only. It shows any special designation for the unit, which will normally
be FIRElink-25.
2.5.2 Firmware
Version
This function is for display purposes only. It shows the version number of the fitted firmware chip.
2.5.3 Run-time
Hours
This function is for display purposes only. It shows the cumulative total number of hours that the device
has run (this is not the time that has elapsed since last power-up, but the sum total of run time since the
detector memory was last reset).
2.5.4 Watchdog
Count
The watchdog is a circuit built into the controller that restarts the controller in the event of a failure to
function properly. This could be as a result of electrical spikes. This count shows the number of
interruptions found. The details of each problem can be found in the event log. See section 6, “Event
Log” for further details.
2.5.5 Device
Text
This function has no current use on the FIRElink-25 but is reserved for future expansion purposes.
2.6 Referencing Tab
2.6.1 Reference
Detector
A FIRElink detector may use another detector as a fresh air reference. This function is the address of the
detector which will be used as the reference. To set a detector as a reference detector, enter its address
as set by its internal DIP switch into this function. This function is disabled by default.
2.6.2 Reference
Enable
Ticking this box enables the reference for the detector, if one has previously been allocated in Reference
detector (see section 2.6.1). This function is disabled by default.
2.6.3 Reference
Level
The value set with this function is the percentage reference signal subtracted from the detector’s signal, if
a reference device has been allocated. The default value is 0.
2.6.4 Reference
Back-off
This value is the delay time between a build up of pollution being seen by the reference (if used) and the
pollution being seen by the detector. The default value is 15.
