EL Electric Latch Retraction Exit Device

The EL Electric Latch Retraction feature provides controlled access through escape doors (via a remote unlocking feature) usually found on the perimeter of a building. EL devices are ‘free from fixings’ hence, safe egress is always available. This feature is available on rim exit devices, surface mounted vertical rod devices and three point latching devices.

Operation

The latch bolt is retracted via any type of reader, switch or push button; changing the status of an exit only or latched door to a push-pull operation. A powerful continuous duty solenoid retracts the latch bolt for momentary unlocking, or for extended periods of time, in lieu of manual dogging.

EL devices are particularly useful in systems incorporating requirements for time controlled access where escape is of paramount consideration. Complete systems will always require a power transfer unit to transfer power from the frame to the door and a custom built power supply unit (See below).

Where To Use the EL Device

Ideal for locking main entrances to high rise blocks of flats (and similar installations) where they can be released by a signal from the intercom system. In short, any heavily vandalized area where the number of daily operations is very high.

Electrical Specification

Solenoid (Continuous Duty) – 24Vdc
Current Inrush (300 milliseconds) – 16 amperes
