6. To check that you were successful, reconnect the power using the red and black wires (as above) and
count the number of green LED flashes. The format can be determined according to the table above.

MOV - Lock Suppression
A metal-oxide-varistor (MOV) is provided with each KeyPAC reader. This device prevents back EMF (high
voltage 'spikes') being returned from the electric lock to the unit. High voltage spikes can cause severe
damage over a period of time, and erratic operation of the system if not controlled.
Failure to fit the MOV at the lock will result in early failure of the unit. It will also invalidate the
warranty.
The MOV (A) should be fitted across the power
terminals of the lock (B).

Before Installing the Reader
Be aware of the following when you choose the locations of your readers:
•
The cable distance from controller to reader should never exceed 3,000 feet (1000m) (with appropriate
cable). Also consider the maximum distance between the controller and the lock.
•
If you use a Request To Exit (RTE) switch, route the wiring so that it is not accessible if the reader is
removed.
•
Ensure that the LED is visible to the keyholder.
•
The best place for a reader is next to the door on the unhinged side at roughly the same height as the
door handle. Check local regulations for ADA compliance.
•
Readers may be located inside or outside.
•
Leave enough room behind the reader for the flying lead.
•
Readers can be mounted behind a non-metallic material, such as glass, plastic or wood without
affecting their reading range.
•
There should be a minimum 3 ft (1m) distance between readers (this includes in and out readers on
opposite sides of a door).
•
Readers can read in the same way from their back as they do from their front. Because of this, ID
devices may work from the other side of the wall on which the reader is mounted.
•
Avoid mounting the reader in direct sunlight.

Installing the Reader
1. Make sure the reader cable is
not
connected to the controller. Route the flying lead behind the reader
and connect it using the crimp connectors supplied. Wire the cable as described in the Wiring section
later in this manual.
2. If the connections are in a location that may be wet or damp, then protect the connectors with a sealing
compound, or use weatherproof crimps.
3. Using appropriate fixings, such as wall plugs, for the surface you are mounting it on, fix the reader to a
flat surface using the screws provided. Install the reader onto a flat and even a surface as possible, as
this will reduce the possibility of it being levered from a wall.
4. For the K3001 and D8301: the two holes are 2.4 in (60 mm) apart. Use the round hole first, then the oval
hole to ensure the reader is straight. Once the reader is mounted in place then the snap-fit décor cover
can be snapped into place. The hole in the cover should line up with the LED. Place the label on the
front of the reader.
5. For the K3002 and D8302 Vandal resistant readers, apply a silicone sealant to any gaps behind the
reader to protect against moisture if the reader is mounted outside. User the Vandal Resistant screws
provided or other suitable fasteners. The LED should be at the top.
3.6
Removing the Reader
The K3001 and D8301 readers can be removed by placing a small flat-bladed screwdriver into the apertures
at the edges of the snap-fit cover. Take care not to damage the reader or cover.
