Frequently Asked Questions (FAQs)

1. Why is an optical smoke detector recommended for bedrooms and escape routes?
Optical detectors respond best to slow-burning, smouldering fires common in upholstery and wiring - typical of bedroom and domestic fires. They provide earliest warning for escape routes where life safety is paramount.

2. How does optical detection differ from ionization detection?
Optical detectors use light scatter to detect visible smoke particles, making them ideal for smouldering fires. Ionization detectors respond better to fast-flaming fires with smaller particles. Optical is preferred for general areas and escape routes.

3. Will this detector false alarm from bathroom steam or cooking fumes?
The optical chamber design provides good immunity to non-fire aerosols, though it's still recommended to avoid installing directly outside bathrooms or in kitchens where steam/cooking fumes could occasionally trigger alarms.

4. What is the recommended spacing for optical smoke detectors?
Typically, detectors should be spaced at maximum 7.5m intervals in corridors and rooms, with no point further than 5m from a detector. Always consult BS5839 and local fire standards for specific requirements.

5. Is this detector compatible with conventional and addressable systems?
This is a conventional detector designed for use with Apollo Series 65 compatible conventional fire alarm panels. For addressable systems, Apollo's XP95 or Discovery ranges would be required.
