Edwards MPSR2-DHTW-GE Weatherproof Double-Action Pull Station

The Edwards MPSR2-DHTW-GE Weatherproof Double-Action Pull Station is a non-coded fire alarm initiating device designed for outdoor applications. It features a rugged red die-cast enclosure, double-action operation, DPDT contacts, hex-screw reset, and terminal connections.

The station is supplied with a weatherproof backbox and is designed to resist corrosion in exposed environments. Its double-action mechanism requires the protective cover to be lifted before the pull handle can be operated.

Double-Action Operation

The MPSR2-DHTW-GE uses a double-action activation mechanism.

The user first lifts the protective front cover and then operates the pull handle. This two-step action helps reduce accidental activation while maintaining straightforward emergency operation.

DPDT Contacts

The MPSR2-DHTW-GE provides:

DPDT — Double-Pole, Double-Throw contacts

This configuration provides normally open and normally closed switching capability for compatible fire alarm and auxiliary circuits. Edwards documentation specifically identifies this model as the DPDT version of the double-action weatherproof MPSR station.

Hex-Screw Reset

The station uses a:

Hex Screw Reset

After activation, authorized personnel can open and restore the station using the appropriate hex tool.

Related MPSR models are also available with Cat 45 key-operated reset mechanisms, but the DHTW configuration specifically identifies the hex-screw reset version.

Weatherproof Design

Its die-cast construction uses pre-painted or plated components to help inhibit corrosion. Edwards’ installation documentation describes the MPSR outdoor stations as high-quality die-cast devices intended for exposed applications.

Break-Glass Capability

The MPSR Series can be operated:

With or without a break-glass rod

Replacement glass rods can be installed without specialized tools. The compatible replacement accessory is:

MPSRGR10 — Replacement Glass Rods, Pack of 10.
