The DorWatcher is an alarm unit used to prevent doors being left open for an extended period of
time.
Ideal to help reduce costly false alarm call outs to the Fire Service caused by smoke from
cooking drifting out of kitchens in halls of residence and triggering fire alarm systems. Ensuring
external doors to buildings are not left open can also help reduce problems caused by vandals
entering communal areas of buildings such as flats or private members clubs.
When the protected door is opened the units LED will flash every few seconds and time delay
TD1 will elapse before a short warning chime is given by the unit. An additional time delay TD2
then elapses. If the door hasn't been closed after times TD1 and TD2 have elapsed, the unit will
give a full alarm tone. If the door is closed before the full alarm tone is heard, the unit will reset
and the next time the door is opened the timers will start again.
Once in full alarm, the tone will continue for 2 minutes after which time the alarm tone will cease
and a chime will be heard every 30 seconds to alert people in the vicinity that the door is still
open. To clear the alarm, close the door.
Overview
Normal Operation

Models available

DorWatcher Inspection
We recommend that DorWatchers installed in locations prone to tampering/vandalism are fitted
with an anti-tamper screw (available separately) and inspected for signs of tampering on a
regular basis.
A simple visual check of the DorWatcher can be made:
Open the protected door, if the LED on the front panel flashes within 10 seconds then the
system is working correctly, if the LED does not flash and the alarm does not activate after the
preset time, contact your installation company for advice.
Battery fault indication
The battery powered DorWatcher model DW304 has a built in Battery fault monitor. If the unit
bleeps as soon as the door is opened, this indicates that the batteries are running low and
should be changed for new batteries (6 x AA).
