Kidde Edwards MPSR1-S45W-GE Spst Pull Station

Product Description

The KIDDE EDWARDS MPSR1-S45W-GE is a single-pole single-throw (SPST) manual pull station with a hex screw reset terminal, designed for use in fire alarm and life safety systems. This device serves as a manual initiating device, allowing building occupants or first responders to trigger a fire alarm signal by pulling the handle. Reset requires a hex key tool, which helps prevent unauthorized or accidental resets after activation. Licensed fire alarm technicians and low-voltage electricians are the primary installers of this device in commercial and institutional fire alarm installations.

This pull station is suited for commercial, institutional, and light industrial applications where a manual initiating device is required as part of a monitored fire alarm system. It is typically installed at exit doors, stairwells, and corridor locations in accordance with NFPA 72 requirements for manual fire alarm box placement. The hex screw reset mechanism supports controlled, accountable reset procedures following alarm events, making it appropriate for facilities that require restricted access to reset functions.

Key Features

• SPST switching configuration for reliable alarm circuit initiation
• Hex screw reset terminal requires a tool for post-alarm reset, reducing unauthorized resets
• Manual pull station form factor for straightforward wall-mount installation at required egress locations
• Sold as a single unit for individual replacement or new installation

Compatibility

Designed as an OEM-style replacement or new-installation manual pull station for commercial fire alarm systems requiring an SPST manual initiating device with tool-reset capability.

Installation Notes

Installation must be performed by a licensed fire alarm technician or low-voltage electrician in compliance with NFPA 72 and applicable local codes. De-energize and place the fire alarm control panel in test mode before wiring or replacing the device to prevent unwanted alarm dispatch. Mount at the required height per NFPA 72 accessibility provisions, and verify correct circuit polarity and supervision continuity after installation. Restore the panel to normal operation and perform a functional pull test before returning the system to service.
