Sensitivity Adjustment
Each environment will vary and Dorgard may need
adjusting to suit your individual environment.
On identifying a necessary adjustment use the small
black Plastic Adjustment Tool supplied. Take care not
to over adjust as this will render the unit inoperative.
Adjusting sensitivity if Dorgard is not sensitive
enough, i.e. does not respond to the fire alarm:
1. Carefully insert the Plastic Screwdriver into hole on
front of the unit.
2. Turn clockwise through no more than 5 degrees (a
small adjustment is equivalent to a large alteration
in sensitivity).
3. Test Dorgard to the fire alarm.
4. If problems persist repeat steps 1-3.
Note. The Adjustment Screw is limited in both
direction, once you can feel resistance against
turning - stop to avoid damaging the unit.
If Dorgard is too sensitive (responds to no apparent
sound) follow steps 1-4, but turn anti-clockwise in
Step 2.
