sounds. DoorSense is designed to react to a
continuous sound of over 65dB when heard
for at least 15 seconds.
DoorSense is incredibly easy to install,
needing no wiring or specialist skills - just

Before you begin…
1Ensure the door has been fitted with a door closer which is
working correctly (UNION have an extensive range of door closers
which are ideal for almost any application)
2The floor underneath the sweep of the door as it opens is level
3The gap between the bottom of the door and the floor is no less
than 5mm (3/16”) so the door can swing over the floor plate
4The door opens to an angle of more than 65°
5The building has a fire alarm system installed which is clearly
audible where the door is fitted

Preparing DoorSense for installation
TIP: If you want to use the release timer, insert
the batteries at 12:00pm (noon) to match the
internal clock to real time.
3A Fully slacken the screw holding the battery
compartment cover with a screwdriver and
lift up from DoorSense unit.
NOTE: the screw will not detach from
compartment.
3B Insert both batteries against the slider of
the battery compartment, in the sequence
shown on the battery slide.
3C Push the filled battery compartment
back into DoorSense unit body and fasten
retaining screw.
2 Set The Optional Release Timer
Turn the unit over to view the timer settings
on the rear.
Using the supplied tool, move switches
to the desired setting shown opposite.
NOTE:
Switch 3 silences the timer release
warning tone.
Switch 4 is not used for the timer release
function.

DoorSense can be used 24/7, which makes it
perfect for continuous traffic applications.
If DoorSense is being fitted to doors in a
building that has periods of no or low usage,
UNION recommend using the time release to
help prevent spread of fire.
DoorSense contains an internal clock which
governs the release timer and the self-testing
features.
The clock is powered by the batteries and
resets when they are removed.
All clock timings are based on 12:00pm (noon)
which is why any replacement of batteries
used in a DoorSense unit should be undertaken
at that time. If this does not suit your situation,
you should calculate any timing differences
between the DoorSense clock time and real
time before adjusting the timer release settings.

the clock resets properly, wait 10 seconds
