Safety Technology Int'l Inc GLR321EX-EN Dpdt Key-to-reset Button

Product Description

The SAFETY TECHNOLOGY INT'L INC GLR321EX-EN is a white, double-pole double-throw (DPDT) key-to-reset push button designed for global exit device applications. This type of switch requires a key to reset the circuit after activation, adding a layer of controlled access to emergency egress and alarm systems. It is typically installed at exit doors, fire alarm panels, or access control points in commercial and institutional buildings. Electricians and low-voltage security technicians are the primary trades responsible for installation and commissioning of this device.

The GLR321EX-EN is suited for commercial exit device systems where a supervised, key-operated reset function is required. Its DPDT switching configuration allows it to control two separate circuits simultaneously, making it appropriate for integrated alarm, access control, or egress applications. The white finish is standard for flush-mount or surface-mount installations in corridors, stairwells, and egress paths where visibility and code compliance are priorities.

Key Features

• Double-pole double-throw (DPDT) switching configuration controls two independent circuits
• Key-to-reset operation prevents unauthorized or accidental reactivation after use
• White finish suits standard commercial corridor and egress installations
• Sold as a single unit for direct replacement or new installation
• Designed for exit device and push button applications in commercial settings

Compatibility

Designed as an OEM-style replacement or upgrade push button for commercial exit device and emergency egress systems requiring a DPDT key-to-reset switching function.

Installation Notes

Installation should be performed by a licensed electrician or qualified low-voltage technician in accordance with applicable NEC requirements and local code. De-energize all connected circuits before beginning wiring work. Confirm switch pole configuration and circuit ratings match the existing system before completing connections. Do not bypass the key-reset mechanism, as it is a functional safety feature of the egress or alarm circuit.
