Manual

Preventative maintenance and regular testing will ensure that Dorgard functions correctly

at all times. Ensure you update the Maintenance Record.

Weekly

Check that the Dorgard Plunger is depressed and is holding the door open. Sound the fire

alarm, after the alarm has sounded for 20 seconds, the door should release to close. If the door

does not release refer to the Trouble Shooting section.

Monthly

Carry out the weekly test and in addition dust the unit checking that the 3 holes for the

Microphone are open and clear of any dust, dirt etc. Dorgard should be cleaned with a slightly

damp cloth. If fitted, check the Floorplate is securely attached and has not been damaged.

6 Monthly

Carry out the weekly and monthly schedule and in addition, check:

1. Under the unit for the condition of the Ferrule.

2. The Dorgard unit is firmly attached to the door.

If any items are worn, torn or damaged then replace immediately. For further assistance or

spare parts contact the Technical Advice Line.

Yearly

Carry out the 6 monthly schedule and replace the Batteries.

Note and Warning

• The unit is designed to detect low battery power or possible faults, it will give a continual

warning (sound a series of beeps) and will Fail to Safe (no longer operate as a hold open

device).

• Dorgard conducts a Self Test 12 hours after Battery insertion, thereafter it will Self Test on

a weekly basis. During the Self Test, if the fire door is held open, Dorgard will release the

fire door. Should Dorgard detect an internal fault it will sound a warning tone and Fail to

Safe.

• If the Self Test at midnight is unsuitable it is possible to change it by pushing the

Dorgard clock forward by re-inserting the Batteries 12 hours before the desired time. e.g.

for a Self Test to occur at Midday the Batteries should be re-inserted at Midnight.
