ideal for emergency exits.
The ACC518 is a Fail Secure lock on power loss perfect for
security doors.
User Information
There are no user serviceable parts, opening or attempting to repair the product will void the
warranty.
Do not install or use the device if the wires connected are damaged or have been subjected to
water ingress.
Handle the equipment carefully. The holding force can be reduced by damaging the lock body.
The strike lock should be fixed tightly in the door frame.
Shut off all power to the access control system before wiring this device.
Maintain a clean and safe environment at all times.
Definition
NO (Normally Open) - This is a contact which remains open (as default) until activated, during the
"active" state the contact provides a closed circuit and starts conducting.
NC (Normally Closed) - Is the opposite of a NO contact. The contact will remain closed (as default)
until activated, during the "active" state the circuit breaks and stops current flow.
Setup Example
The ACC520 is a Fail Safe strike lock making it ideal for
emergency exits. They work by keeping the door locked
until power is cut when an emergency exit button is
pressed or the building loses power. When the this
happens the doors will unlock allowing staff and visitors
to safely leave the building.
This example shows a the ACC520, when the
button is activated, power supply then releases
power from the lock, and if power is lost then the
lock also releases.
Connect the control device and power to the lock via an
access control panel, relay or exit button so that the
power can be cut when triggered.
For a Fail Secure setup the ACC518 strike lock works the
opposite way to most electronic locks as they are
designed to lock the door when their power is cut.
The lock can also be connected to a HRM250 - 10
function relay. A custom set length of time can be
set for how long the power is cut from the lock.
This symbol indicates that equipment must not be mixed with general household waste. For treatment, recovery and recycling please return to your local designated
WEE/CG0783SS collection point as defined by your local council.

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.
Red = +12V DC
Black = GND
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.
