Troubleshooting
In the rare event of an issue with the device’s operation, refer to the points below:
Device not releasing upon a fire alarm condition?
Check that the device is added correctly to the system and that it is fault free at
the FireCell radio hub.
Check that the door closes freely when closed manually.
Check that the plunger has a minimum of 10mm clearance between the ferrule
and the floor / floor plate.
Check that the WDC’s output properties are set correctly within the control panel
programming.
Why does the fire door not close freely?
Check that the ferrule is not worn or damaged. Replace as necessary.
Check that the plunger has a minimum of 10mm clearance between the ferrule
and the floor / floor plate.
Device not holding the door in an open position
Check that the plunger is depressed fully.
Check that the device is added correctly to the system and fault free at the
FireCell radio hub.
Check that the device is positioned low enough for a good connection between
the ferrule and the floor plate. The optimum plunger movement is 10 - 15 mm.
Device in tamper fault?
Check that the device is fixed correctly to the door.
Check that the surface is flat and that the tamper switch is engaging correctly,
when the device is fixed to the door.
Battery fault / device not powered?
Check the polarity and the voltage of the batteries.
Check that the battery cover is fitted correctly.
Do NOT Press the log on button on a pre-programmed device, as this will cause
communication with the control panel to be lost. Should this happen, delete the
device from the system and add it back on.
