Honeywell Silent Knight PS-DA Dual Action Key Reset Pull Station

Product Description

The Honeywell Silent Knight PS-DA is a dual action key reset pull station designed for fire alarm systems. It requires two deliberate actions to activate, reducing the likelihood of accidental trips. The key reset mechanism means only authorized personnel with the correct key can restore the station to its normal standby state after activation. This pull station is installed by licensed fire alarm technicians as part of a listed fire alarm system.

The PS-DA is suited for commercial and light industrial fire alarm installations where manual initiation devices are required. It is typically mounted at exits, corridor intersections, and other code-required locations throughout a protected building. The dual action design meets requirements for applications where tamper resistance and deliberate actuation are priorities.

Key Features

• Dual action activation requires two separate deliberate motions to reduce accidental or false alarms
• Key reset mechanism restricts station restoration to authorized personnel
• Designed for surface or semi-flush mounting at standard fire alarm pull station locations
• Sold individually as a single unit

Compatibility

Designed as an OEM-style manual initiating device for use within listed fire alarm control panel systems requiring addressable or conventional pull station inputs. Refer to system documentation to confirm compatibility before installation.

Installation Notes

Installation must be performed by a licensed fire alarm technician in accordance with NFPA 72 and all applicable local codes. The fire alarm control panel must be placed in test mode and power isolated from the initiating device circuit before wiring or mounting work begins. Mount at the code-required height of 42 to 54 inches above finished floor unless local authority having jurisdiction specifies otherwise. Do not restore the system to normal operation until all wiring connections have been verified and the pull station has been functionally tested.
