Trouble shooting
The following are the most frequently asked questions regarding Dorgard, with a quick checklist
to follow.
1) Dorgard is not releasing to Fire Alarm
• Check fire alarm sounds for at least 30 seconds.
• Check door is free to close unhindered.
• Check that the plunger has a minimum of 10mm of down travel before the ferrule contacts
the floor.
• Check the fire alarm is louder than 65dB where Dorgard is situated.
• Calibrate unit if required (see page 8 Adjusting Sensitivity of Dorgard).
2) Dorgard releases to no apparent sound
• As a safety feature, Dorgard has to release to any sound that it hears as being continuous and
louder than 80dB as this sound could be obscuring a potential fire alarm.
• Check that Dorgard is on the side of the door that closes into the door frame.
• Dorgard will release if the door is pushed in the direction of opening (see page 6 Operating
Dorgard). To prevent this happening fit the the floorplate supplied.
• Dorgard will release every 7 days as part of its self-testing routine.
• Calibrate unit if required (see page 8 Adjusting Sensitivity of Dorgard).
3) Door creeps closed with plunger fully depressed
• Check that the ferrule is not worn or damaged. Replace if necessary.
• Check that Dorgard is positioned low enough that the ferrule makes good contact with the
floor when the plunger is depressed. A vertical plunger movement of 10 - 15mm is ideal.
Re-position as necessary or fit floorplate supplied.
• Check that the door closer does not shut the door with excessive force. If so, fit the floorplate
supplied or loosen pressure on closer.
• Check that the ferrule has enough purchase on the floor surface ie: floor surface is not too
slippery. If so, fit the floorplate supplied.
4) Dorgard does not retain the door in an open position
• Check that the plunger is depressed while standing side on (see page 6 Operating Dorgard).
• Check that the battery compartment is closed and that the batteries are operative.
• Check that Dorgard is not fitted too low on the door. A vertical plunger movement of
10 - 15mm is ideal for the plunger to lock down properly.
• Check that Dorgard is mounted on the side of the door that closes into the door frame.
• If all the above points are satisfied and further assistance is required please
contact your supplier.
