The Apollo Series 65 Optical Smoke Detector (Model 55000-315) delivers reliable smoke detection using advanced optical sensing technology. Designed with a built-in magnetic test switch and a flashing LED indicator, it allows for easy maintenance and visual confirmation of operation. Operating on a supply voltage range of 9–33 VDC, this detector offers high performance, durability, and compliance with safety standards, making it ideal for commercial, industrial, and institutional fire safety applications.

Key Features

• Optical (Photoelectric) Detection
  Uses light-scattering technology to detect smoke particles—especially effective for slow-burning, smouldering fires
• Flashing LED Status Indicator
  LED remains clear in standby and turns red in alarm, giving immediate visual confirmation
• Magnetic Test Switch
  Allows easy functional testing without dismantling the unit, simplifying maintenance
• Stable in Harsh Conditions
  Unaffected by wind or atmospheric pressure changes, ensuring consistent performance
• Wide Voltage Compatibility
  Operates across a broad 9–33 VDC range, suitable for most fire alarm panels
• Proven Series 65 Platform
  Electrically and mechanically compatible with other Series 65 detectors and bases
