Paradox SD360-3R5 Wireless Ceiling-Mounted Smoke Detector (Manufactured by Everday)

The Paradox SD360-3R5 is a high-sensitivity, standalone wireless photoelectric smoke detector designed to provide early fire detection for residential and commercial environments. Manufactured by Everday for Paradox security systems, it uses advanced optical sensing technology to detect smoldering fires rapidly while minimizing false alarms caused by cooking fumes or steam.

Engineered for seamless wireless communication, the SD360 operates on a 433 MHz RF transmission frequency, allowing it to interface directly with Paradox Magellan control panels (such as MG5050+ and MG5075) or Spectra SP and Digiplex EVO systems equipped with an RTX3 wireless receiver. It features a built-in 85 dB piezo siren for local acoustic alerts, a flashing LED indicator for visual status, a manual test/hush button, and automatic low-battery monitoring to ensure continuous 24/7 life safety protection.

Key System Features & Functionality

• Photoelectric Sensing Chamber: High-precision optical detection chamber provides reliable, early detection of smoldering fires and airborne smoke particles.

• 433 MHz Wireless Integration: Built-in RF transmitter seamlessly transmits alarm, tamper, and low-battery signals to Paradox wireless panels and receivers.

• Integrated 85 dB Piezo Sounder: High-decibel local acoustic siren triggers immediately upon smoke detection, independently of control panel sirens.

• Manual Test & Silence Button: Large, accessible front button enables quick monthly functional testing and temporary alarm silencing.

• RF Supervision & Low-Battery Warnings: Periodically transmits supervision signals to the main panel and provides visual/audible local chirps when battery replacement is needed.

• Ceiling Surface Mounting: Compact circular design with twist-lock mounting bracket for fast, tool-free installation and easy battery maintenance.
