This allows for installations where the exit button
isn't situated next to the door and a timed
released is required.
Mounting
Cut the hole for the electric bolt in the door
frame.
Ensure a channel or hole is made for the
cables and ensure they are protected by
using a protection guard or conduit if
exposed.
Then fix the lock to the door frame and the
plate to the door using the screws provided.
Connections
The strike locks are provided with screw terminals which can
be soldered to the incoming power connections.

Troubleshooting
If the door release is not activating the lock then there is likely a shorted wire, open circuit or some
other failed device in the circuit.
To identify where the fault is, each wired connection in the circuit needs to be tested; working from
the door release progress through, including the power supply and the lock.
If the fault is with the door release then check the connection wires for continuity and for trapped
wires. Check for water ingress on the wired connections. Check the polarity in the power connections
and ensure the connections are connected to the proper terminals.
