Alarm Controls Corporation KR-1 Latching Key Reset Push Button

Product Description

The ALARM CONTROLS CORPORATION KR-1 is a latching key reset push button with one normally open and one normally closed contact. It is designed for use in access control and egress systems where a keyed reset mechanism is required to restore a latched circuit to its normal state after activation. Licensed electricians and security system technicians typically install this device in commercial and light industrial settings. The KR-1 provides a secure, tamper-resistant reset function by requiring a physical key to unlatch the switch, preventing unauthorized restoration of the circuit.

The KR-1 is suited for commercial access control installations, including door release systems, emergency egress stations, and push button control panels. It is used in applications where a momentary or latching switch must be reset only by authorized personnel with a key. This makes it appropriate for building entry control points, security checkpoints, and life-safety egress hardware installations where controlled reset is a code or operational requirement.
