SD500-PS Addressable Pull Station

The SD500-PS Addressable Pull Station is Silent Knight’s single-action addressable manual fire alarm station for the SD500 intelligent device family. A single-action pull station requires only one motion to activate ideal for situations where the fastest possible occupant response is the overriding priority, such as along egress paths in offices, retail spaces, and light commercial settings. Because the SD500-PS is addressable, each pull station reports its individual identity to the Silent Knight fire alarm panel, giving facility teams precise location information the moment it’s activated. The station is designed to sit comfortably in Silent Knight SD500-based installations alongside other SD series field devices.

Features

  • Single-action activation one motion triggers the alarm
  • Addressable reporting on the Silent Knight SD500 series
  • Precise identification of the specific pulled station at the panel
  • Suitable for egress corridors and exit proximity locations
  • Compatible with existing SD500 intelligent device ecosystems
  • Commercial-grade housing for long-term corridor use
  • Reset-tool design consistent with Silent Knight SD series

Benefits

Choosing the SD500-PS over a conventional non-addressable pull station is about response-time precision. When an SD500-equipped facility is hit with a pull activation, the panel doesn’t just know a zone tripped it knows which specific station tripped, which corridor it sits in, and (with proper mapping) which floor and wing. That information flows directly to mobile responders, on-site security, and central stations, cutting search time dramatically. Single-action activation is the right choice along primary egress routes because it maximizes how quickly a person in stress can activate the alarm. For building owners, that combination addressable precision plus single-action speed translates into measurably better alarm initiation performance.

How does the SD500-PS differ from a conventional pull station?
The SD500-PS is addressable, it reports its own unique identity to the Silent Knight panel whereas conventional stations only tell the panel that somewhere in a zone, a station was pulled.
Why pick single-action over dual-action at a given location?
Single-action stations activate fastest because only one motion is needed the preferred choice along primary egress routes where response speed matters most.
Is the SD500-PS fully interoperable with other SD500 field devices?
Yes, as part of the SD500 intelligent device ecosystem, the SD500-PS integrates alongside SD500 detectors, modules, and bases on the same addressable loop.
What should happen on the panel side after a SD500-PS activation?
The Silent Knight panel displays the specific pull station's address and descriptor, logs the event, and triggers notification per the site's alarm programming.
Do I need a special reset tool for the SD500-PS?
Yes, resetting an activated SD500-PS requires the appropriate Silent Knight reset key; generic keys are not recommended to avoid damage.
Is the SD500-PS approved for outdoor corridor use?
Standard SD500-PS stations are designed for indoor fire alarm use; outdoor-rated applications typically require weatherproof enclosures or environmentally rated variants.
How many SD500-PS stations can share one addressable loop?
Loop device count depends on the Silent Knight panel's total SD500 device capacity; pull stations count as one addressable point each toward that loop loading.
