Normally free interlocks
Made in Britain
Description

These are normally free door interlock controllers. When all doors are closed, their contacts are closed & are wired to release the other door(s). As soon as any door opens' its contacts lock the other doors immediately, and they stay locked until the first door's contact closes again. This then allows another door to open.

Note:

Indicators:It is recommended that door lock indicators are fitted to show the door status, such as the DA340

Violate: As the doors are normally unlocked, it is possible to open both doors together if perfectly synchronised. Careful positioning of the reed and magnetic locks can reduce, but not eliminate, the possibility.

Operation of DA726

Example (DA726-3): Door A is opened, door B & C will lock until door A is closed.
