INSTALLATION

System 2 Installation / Programming Manual

Door Locks

Direct Current (DC) door strikes or DC magnetic door holding devices (mag locks) require a diode be installed

across the door lock coil. A 1N4001 diode or equivalent is wired at the door lock, parallel to the coil with the

striped end (cathode) to the positive side of the coil.

Door Strike Overview

The Corby 12VDC Door Strike (p/n 4253) is made for commercial or residential retrofit, and can be used with

wood or steel frame doors. This ANSI Door Strike is designed to minimize installation time in all standard door

frames and strike plates. It is also rated at 900 lbs. holding force. This strike is not rated as continuous duty.

If a time schedule is necessary, and a door strike is specified, a continuous duty Door Strike must be used. AC

door strikes are not recommended because they generate electrical noise and Electro-magnetic Interference.

Corby Door Strikes are designed to be used with a wide range of door thicknesses from

1 3/8” to 2 3/8”. The “strike plate” dimension measures 1 1/4” X 4 7/8”.

Door Strike Wiring

Door Strikes that draw less than 1 amp can be wired to the System with 20 AWG solid or stranded wire for

runs up to 50 ft. For longer runs or for door strikes that draw more than one amp, use 18 AWG, or larger,

wire. Power for all door locking devices must be supplied from external power sources, no lock power is

available from the System 2. AC door strikes are not recommended and should not be used.

Magnetic Lock Overview

The Corby 12VDC Magnetic Locks are extremely well suited for high traffic doors; there are no bars, bolts,

safety latches or other moving parts that can stick or bind and thus prevent exit.

The Magnetic Lock is Fail Safe, the door is unlocked when the power is interrupted. Since they use DC, they

operate silently, without any buzz or hum. They are rated at 1500 lbs of holding force.

Typical uses are securing emergency exits, escape doors or any other Access Controlled door.

Corby Magnetic Locks are designed to be used with doors that swing out. Corby supplies the necessary

mounting templates to make installation even easier.
