Which Apollo smoke detector do I need?
- XP95: Apollo's long-established addressable range. The XP95 optical smoke detector (55000-600APO) works on panels that support the Apollo XP95/Discovery protocol.
- Discovery: addressable detectors on the same protocol, with selectable response modes so sensitivity can be matched to the area.
- Soteria: Apollo's newer addressable range; check the panel supports it before ordering.
- Series 65 and Orbis: conventional detectors for zoned conventional panels.
- AlarmSense: detectors for Apollo AlarmSense two-wire systems.
- XPander: radio detectors that add wireless devices to compatible addressable systems.
Always match the replacement to the panel type and protocol, and replace like for like where possible. Most Apollo heads are sold without a base: see detector bases. More: XP95 and Discovery detectors, Series 65 detectors, all smoke detectors and smoke detector testers.
Apollo smoke detector FAQs
Can I replace an XP95 smoke detector with a Discovery detector?
Discovery detectors use the same communication protocol as XP95, so they are often used on the same panels, but check the panel manufacturer's compatibility and the system design before mixing ranges.
Can a Series 65 detector be used on an addressable panel?
No. Series 65 and Orbis are conventional detectors for conventional panels. Addressable panels need addressable detectors on the matching protocol.
What does the flashing LED version mean?
Some Apollo detectors are offered with an LED that flashes in normal operation as a visible sign the detector is powered; others light only in alarm. The part number tells you which version you are ordering.
