Honeywell Silent Knight SD505-PHOTO Addressable Smoke Detector

Product Description

The Honeywell Silent Knight SD505-PHOTO is an addressable photoelectric smoke detector designed for use in addressable fire alarm systems. It uses light-scattering photoelectric sensing technology to detect the presence of smoke particulates in the air, triggering an alarm signal that is communicated back to the main fire alarm control panel. The detector is individually addressed on the loop, allowing the panel to pinpoint the exact device location during an alarm or trouble condition. Installation and commissioning are typically performed by licensed fire alarm technicians.

The SD505-PHOTO is suited for commercial and light industrial fire alarm applications where addressable detection is required. It integrates with Silent Knight addressable fire alarm control panels and loop wiring infrastructures. The addressable design supports large-scale installations where individual device identification is essential for code compliance and rapid emergency response. This detector is noted as discontinued by the manufacturer; installations requiring this device should verify availability of replacement or successor models.

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 and loop circuit must be powered down and isolated before mounting or wiring the detector. Verify address programming requirements for the specific control panel in use before commissioning. Do not install in environments outside the detector's rated temperature and humidity range as specified in the manufacturer data sheet.
