Automatic Night Time Release
continued
To set Dorgard's internal clock to 12.00 noon the batteries must be installed at 12.00 noon. It
will then operate at the times indicated opposite. Dorgard does not take into account winter or
summer time and therefore does not adjust automatically for daylight savings.To reset Dorgard's
internal clock, remove the batteries, wait 10 seconds and re-insert them at 12.00 noon.
Install batteries at noon
Self tests automatically at midnight
Dorgard carries out a self-test every 7 days checking for any possible problems or defects,
should it detect any faults it will emit a beep pattern and Fail to Safe (refer to Beep and LED
Messages Explained, page 10).
Important Note: It is recommended that the warning tone is NOT disabled.The warning tone
is to alert persons using the building that the door is about to close and is a safety feature. It is
recognised however, that in some locations the warning tone at night may cause a disturbance. It
is for this reason alone that the provision of disabling the night time tone has been made.
After installing the batteries Dorgard sounds a long tone, followed by a mechanical
sound (Dorgard setting), then 3 x single tones. These 3 tones indicate the dip switch selection,
Low tone = Off, High tone = On. For example, if the dip switches are selected as follows:
No:1 = On, No:2 = Off, No:3 = Off, the tones will then sound High, Low, Low.
Batteries-Alkaline Only
(Do Not Use Rechargeable Batteries)
The 2 x C Size Procell Alkaline batteries supplied should last for at least 12 months. Dorgard
continually checks the battery life ensuring safe operation.
Insert the batteries into the battery compartment (+) positive side facing up. Inserting the
batteries the wrong way could cause internal damage. When closing the battery compartment
use a Phillips / Pozidrive No.2 screwdriver, taking care not to over tighten.
When the batteries require changing Dorgard will Fail to Safe (no longer work as a hold open
device). A warning beep will sound until the batteries are exhausted, removed or replaced with
new ones. Battery life may be reduced in noisy environments!
