This Alpro ANSI style release is suitable for use on metal and timber doors. Often used in conjunction with latches, including narrow style dead latch mortice locks found on aluminium doors. The item features a 124mm long stainless steel faceplate, selectable 12v or 24v operation (when wiring) and is field reversible between fail-safe and fail-secure modes. An additional RM1 rectifier module can be purchased separately which allows the release to be run on AC power if required. Speak to our technical team for further information.
