Silent Knight SK-PHOTO-W Addressable Photoelectric Smoke Detector with Base

Product Overview

The Silent Knight SK-PHOTO-W Addressable Photoelectric Smoke Detector is an intelligent, two-wire smoke detector designed for compatible Silent Knight fire alarm control panels. It combines a modern, contemporary design with an enhanced optical sensing chamber engineered to detect smoke from a wide range of combustion sources.

Designed for both performance and installation efficiency, the SK-PHOTO-W uses photoelectric sensing technology and communicates directly over a two-wire signaling line circuit (SLC). Its addressable architecture allows each detector to be individually identified by the fire alarm control panel, helping pinpoint the exact location of an alarm or detector requiring maintenance.

The detector features rotary decimal addressing, allowing installers to assign an individual device address. Point ID capability can help identify specific detectors when chamber contamination reaches an unacceptable level, supporting selective maintenance instead of requiring unnecessary inspection of every detector on the system.

The SK-PHOTO-W also provides continuously monitored sensitivity that can be programmed through compatible control panel software. Its built-in device-type identification and communication functions allow the control panel to recognize the connected detector.

A pair of bi-color LEDs provides a 360° viewing angle for visual status indication, while LEDs blink whenever the detector is polled. The detector also supports remote testing from the compatible fire alarm control panel.

Addressable Photoelectric Smoke Detection

The SK-PHOTO-W uses photoelectric sensing technology to detect smoke within the protected area. Its enhanced optical sensing chamber is engineered to provide reliable smoke detection across a broad range of combustion sources.

As an addressable detector, the SK-PHOTO-W communicates its individual device information to the compatible fire alarm control panel. This allows the system to identify the specific detector associated with an alarm or service condition.

Individual Device Addressing

The detector features rotary decimal address switches, allowing each device to be assigned a specific address on the fire alarm system.

Individual addressing provides useful location information for larger installations because the control panel can identify the particular detector involved in an alarm or maintenance condition. This can simplify troubleshooting and help direct technicians to the correct location.

Always refer to the applicable Silent Knight fire alarm control panel documentation for supported device capacity and addressing requirements.

Programmable Sensitivity and Maintenance Monitoring

The SK-PHOTO-W Series allows detector sensitivity to be programmed through compatible control panel software. The detector’s sensitivity is continuously monitored and reported to the panel.

Its Point ID capability can also help identify when chamber contamination reaches an unacceptable level, allowing maintenance personnel to identify the specific detector requiring attention.

This approach can improve maintenance efficiency by helping technicians focus on individual devices rather than inspecting every detector unnecessarily.

Two-Wire SLC Communication

The SK-PHOTO-W connects to compatible fire alarm control panels using a two-wire SLC connection. Its integrated communication circuitry and built-in device-type identification allow the control panel to recognize the detector and communicate with it over the signaling line.

The detector is designed for use with compatible Silent Knight fire alarm systems, including supported panels in the 6820EVS, 6808, 6700, 5700, 5808, 5820XL, and 5820XL-EVS families.

360° Visual Status Indicators

Two integrated bi-color LEDs provide a 360° viewing angle, allowing the detector’s visual status indicators to be seen from different directions around the device.

The LEDs also blink when the unit is polled by the fire alarm control panel, providing a visual indication of system communication.

Remote Testing

The SK-PHOTO-W supports a remote test feature from the compatible fire alarm control panel, providing an additional option for system testing and maintenance.
