C106 Keypad

Electric Lock Release

When installing lock releases please allow a little movement on the door as

operation will be impaired if fitted too tightly.

The C106 Keypad provides two alternative pairs of connections for direct

connection of an electric lock releases:-

‘FAIL SECR’ : Use these connections for ‘Fail-Secure’ lock releases. These

devices require power to release the lock and will secure the door in the event

of power failure. These are the most commonly used lock releases.

‘FAIL SAFE’ : Use these connections for ‘Fail-Safe’ lock releases and magnetic

locks. Both of these devices require continuous power to lock the door and will

release the door if power fails.

Note ‘Fail Safe’ lock releases are DC only

These outputs are rated at the input voltage (12V D, 12V A) with a maximum

current consumption of 0.5A.

High Current Lock Releases

For a lock release or a magnetic lock rated higher than 0.5A an additional power

supply will be required. In addition a relay must be used to interface with the

C106 Keypad.

The relay contacts, or the lock-release, must be fitted with a suitable suppression

device to prevent voltage transient and electromagnetic interference being

generated by the coil of the lock release. (Refer to manufacturer for further

advice).

Consideration should be given to the problem of a voltage drop at the lock

release. Please refer to the manufacturer of the particular lock release for

information on suitable cable length versus thickness and power supply rating.
