DA550
A 2 door interlock system that monitors the states of both doors. Upon request, the unit will release a door for a pre-determined period of time, only if the other door is secure (i.e. door not released and door contacts closed). The unit is supplied in a metal case, suitable for wall mounting. Other variants are available, information available upon request. 12V DC operation. Metal Cased.

DA560
A 3 door interlock similar to the DA550 but microprocessor controlled for greater functionality. The unit can be supplied with optional sets of changeover contacts for timer alarm and violate outputs.
The timer alarm contacts change over if a door, having been opened, is not closed in a pre-determined time. The time is user selectable (see Technical Information).
The violate contacts change over if more than one door is open at a time (e.g. if a closed door is forced). 12V DC operation.
Metal Cased.
