INSTALLATION INSTRUCTIONS
350 NARROW LINE EMLOCK
Electrical Instructions:
Use properly fused U. L. Listed Power Supply
Do not install a diode in parallel with any magnetic lock. A diode
will cause a delay when releasing the door and residual magnetism
to occur.
Access controls and/or release contacts must be located in series
with the positive (+) power lead of the EmLock.
Any low voltage condition will cause erratic operation of the
optional board sensor.
Although SDC recommends the use of a Regulated DC power supply.
A significant voltage drop will occur when using a full wave bridge rectifier.
