Alarm Controls Corporation KR-1-4-GR Latching Key Reset Contact

Product Description

The Alarm Controls Corporation KR-1-4-GR is a latching key reset contact switch finished in red, designed for use in access control, egress, and door monitoring systems. The unit requires a key to reset after activation, providing a positive-confirmation mechanism that prevents unauthorized or accidental reset of the circuit state. It is typically installed by licensed electricians or low-voltage security technicians as part of a coordinated exit device or alarm circuit in commercial and institutional buildings.

The KR-1-4-GR is suited for applications where a supervised, latching contact is required in exit device assemblies or push-button control stations. Its red finish aids visual identification in egress corridors, stairwells, and door hardware panels where color-coded controls are part of the installation design. It is commonly integrated into fire alarm door-holder release circuits, access control panels, and emergency egress systems in commercial facilities.

• Latching contact mechanism holds circuit state until key reset is performed
• Red finish supports color-coded identification in exit device and control panel installations
• Key reset operation prevents unauthorized or accidental circuit restoration
• Designed for access control, egress monitoring, and supervised alarm circuits
• Sold as individual unit for single-point installation or replacement use

Compatibility

Designed as an OEM-style replacement or new-installation component for commercial exit device assemblies and low-voltage push-button control stations requiring a latching key reset contact.

Installation Notes

Installation should be performed by a licensed electrician or qualified low-voltage technician in accordance with applicable NEC requirements for control and signaling circuits. De-energize the circuit and verify lockout-tagout procedures before wiring or replacing the contact. Consult the manufacturer product manual for wiring diagrams and mounting dimensions specific to this unit. Do not apply power to the circuit until all connections are verified and the enclosure is properly secured.
