The ICM-2 is a compact 2 door interlock controller allowing 2 functions of interlock control. It can be used for 2 doors requiring a standard ‘Air Lock’ function. Alternatively, the ICM-2 can be set up to allow an auto locking function. The ICM-2 can be used with normally-open or normally-closed door contacts by cutting the appropriate link.
Standard operation: if one door is open the locked door cannot be accessed until both are closed.
Auto-lock operation: if 2 doors need to be unlocked, one door is only locked when the other is opened.
