Brand Information
XP95A uses a ‘central intelligence’ system where all the decisions are made by the control panel. Each detector is addressed using Apollo’s patented XPERT Card and supplied with the mounting bases. The XP95A product line includes an ionization detector, a photo-electric detector, a heat detector, a multisensor, an isolator and a series of modules.

Electrical Description
The XP95A Photoelectric Smoke Detector is designed to be connected to a two wire loop circuit carrying both data and a 14 V to 22 V dc supply. The detector is connected to the incoming and outgoing supply via terminals L1 and L2 in the mounting base. A remote LED indicator requiring not more than 1 mA may be connected between the +R and L2 terminals. An earth connection terminal is also provided. The detector is calibrated to give an analogue value of 25±7 counts in clean air. This value increases with smoke density. A count of 55 corresponds to the UL alarm sensitivity level.
Operation
The XP95A Photoelectric Smoke Detector is distinguished by the indicator LED which is clear in standby and red in alarm. Within the case is a printed circuit board which on one side has the light proof labyrinth chamber with integral gauze surrounding the optical measuring system and on the other the address capture, signal processing and communications electronics.
An infrared light emitting diode within its collimator is arranged at an obtuse angle to the photo-diode. The photo-diode has an integral daylight blocking filter.
The infrared LED emits a burst of collimated light every second. In clear air the photo-diode receives no light directly from the infrared LED because of the angular arrangement and the dual mask. When smoke enters the chamber it scatters photons from the emitter infrared LED onto the photo-diode in an amount related to the smoke characteristics and density. The photo-diode signal is processed by the optical ASIC and passed to the A/D converter on the communications ASIC ready for transmission when the device is interrogated.
Environmental Characteristics
The XP95A Photoelectric Smoke Detector is unaffected by wind or atmospheric pressure and operates over the temperature range -4°F to +140°F
Product Information
The XP95A Photo-Electric Smoke Detector works on the light-scatter principle and is ideal for applications where slow-burning or smoldering fi res are likely.
Key Features
Responds well to slow-burning, smoldering fires
Well suited for bedrooms and escape routes
Unaffected by atmospheric pressure
