Product details
The Apollo 55000-317APO is a conventional optical smoke detector from the popular Apollo Series 65 range. A trusted Apollo smoke detector for conventional fire alarm systems, it responds well to slow-burning, smouldering fires and is well suited to bedrooms and escape routes.
The Series 65 Optical Smoke Detector uses light sensing technology to “see” smoke entering the chamber. The external detector moulding is identical to that of the ionisation detector, and has an indicator LED which is clear in quiescent state and produces a red light in alarm.
Used for: conventional fire alarm systems in offices, schools, residential blocks, hotels and escape routes where smouldering fires are the main risk.

Frequently asked questions
Does the 55000-317APO come with a base?
No, the detector head is supplied without a base. Choose one of the Series 65 bases listed above (standard, diode, relay or Sav-wire) to suit your system design.
Is this an addressable or conventional smoke detector?
The Series 65 is Apollo’s conventional range, operating from 9 to 33 V DC. For analogue addressable Apollo systems, see the Apollo XP95 Optical Smoke Detector (55000-600APO).
When should I use an optical rather than a heat detector?
Optical smoke detectors respond well to slow-burning, smouldering fires and suit bedrooms and escape routes. Heat detectors are typically chosen for areas such as kitchens where smoke or steam could cause unwanted alarms.
