17063 Ver 1.6 DRAFT B 7 Easikey Readers
Notes
1. The ends of any cores not used on the suppression cable can be snipped off.
2. If the controller is an Easikey then there is no Door Contact option available and the
Brown core on the suppression cable is not used.
5.3 MOV - Lock Suppression
A metal-oxide-varistor (MOV) is provided with each reader. This device prevents back e.m.f.
('spikes') being returned from the electric lock to the controller. This can cause severe damage
over a period of time, and erratic operation of the system if not controlled.
A B
The MOV (A) should be fitted across the power terminals of the lock (B). It can be fitted across
the relay contacts on the controller, but this will be less effective.
Important Notice
If the reader is installed externally, then the terminals on the rear of the reader
MUST be sealed with a silicone compound to prevent corrosion.
