Preventative maintenance and regular testing will ensure that Dorgard is performing at its best at
all times.
Weekly
Check that the Dorgard plunger is pressed down and is holding the door open. Sound the fire
alarm and within 4 seconds the red light on the top of the Dorgard should start flashing once
every second. This indicates that the Dorgard is hearing the 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 (page 9).
Monthly
Carry out the weekly test and in addition dust the unit checking that the 3 holes for the
microphone are clear of any dust, dirt etc. Dorgard should be cleaned with a slightly damp cloth.
If fitted, check the floor plate 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 see
contact details on back cover.
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).
•
Noisy environments may reduce battery life. If this is the case then the replacement schedule
should be altered accordingly.
All maintenance and testing should be completed by a competent person. A formal record
should be kept in a safe place.
