Adjusting the Dorgard Unit
Each location will vary and Dorgard may need adjusting to suit your individual location.
On identifying a necessary adjustment use the black plastic screwdriver provided. Take care not
to over-adjust as this will render the unit inoperative.
Adjusting the sensitivity of Dorgard
If Dorgard is not sensitive enough (ie: won’t respond to alarm)
1) Carefully insert the black plastic screwdriver into the adjustment hole on the front of the unit.
2) Turn screwdriver clockwise through no more than 5 degrees (a small adjustment with the
screwdriver is equivalent to a large alteration in the sensitivity).
3) Sound fire alarm for a minimum of 30 seconds and ensure that Dorgard releases to the fire
alarm.The LED will flash once a second if it hears the fire alarm.
4) If the problem still persists repeat steps 1-3.
Note:
The adjustment screw is limited in both directions, once you can feel resistance against
turning – stop to avoid damaging the unit. If Dorgard still fails to respond to alarm, consider points
in Trouble shooting section. If further assistance is required contact your supplier.
If Dorgard is too sensitive (ie: releases to no apparent sound)
Follow Steps 1-4 above, but turn screwdriver anti-clockwise in Step 2.
