Product details
The Apollo XPA-OP-12034-APO is the XPander wireless smoke detector head, extending Apollo XP95, Discovery or CoreProtocol addressable systems by radio.
The Apollo XPA-OP-12034-APO is the XPander wireless optical smoke detector head. XPander is Apollo's wireless (radio) extension to its addressable range: a loop-powered radio interface communicates with the control panel using the XP95, Discovery or CoreProtocol addressable protocol, and with the XPander devices by radio. This part is the detector only; it fits the XPander mounting base, which is supplied with the combined detector and base (XPA-CB-12034-APO).
XPander optical detectors are recommended as general-purpose smoke detectors for early warning of fire in most installations, and are ideal where slow-burning or smouldering fires are likely.

Frequently asked questions
Does this include the base?
No, this part is the detector only. It fits the XPander mounting base, which is supplied with the combined detector and base (XPA-CB-12034-APO).
Which Apollo protocols does XPander work with?
A loop-powered radio interface communicates with the control panel using the XP95, Discovery or CoreProtocol addressable protocol.
Where should an optical detector be used?
XPander optical detectors are recommended as general-purpose smoke detectors for most installations, and are ideal where slow-burning or smouldering fires are likely.
