Apollo 55000-600APO — XP95 analogue addressable optical smoke detector using forward light scatter.
Optical detection responds to the larger particles thrown off by slow-burning and smoldering fires, where an ionization detector would respond late. An infrared emitter fires a burst once per second at an obtuse angle to a silicon PIN photo-diode; smoke entering the chamber scatters photons onto it in proportion to density.
- Supply voltage 17 V to 28 V dc, two-wire and polarity insensitive
- Quiescent current 340 µA; power-up surge 1 mA for 1 second; alarm LED 4 mA
- Nominal response threshold 0.12 dB/m to EN 54-7
- 25 counts in clean air, tolerance 7; a count of 55 is the EN 54 alarm level
- Operating temperature -20 °C to +60 °C; 0% to 95% RH, no condensation
- 100 mm diameter × 42 mm height, 105 g; white polycarbonate
XP95, Discovery and CoreProtocol compatible; compliance for this part is CPR and LPCB. 55000-620 is the same detector with wider approvals, 55000-660 is black, and 55000-640APO is the intrinsically safe version. The XP95 ionization detector shares this case and differs only by its LED.

FAQ
Which protocols is the 55000-600APO compatible with?
XP95, Discovery and CoreProtocol digital communication.
Is a base included?
No. Approved bases are the 45681-210 XP95 mounting base and the 45681-209 XP95/Discovery standard deep mounting base.
What supply does it need?
17 V to 28 V dc on a two-wire, polarity-insensitive loop, with a quiescent current of 340 µA.
What approvals does this part number carry?
Part 55000-600 is CPR and LPCB only. The 55000-620 version carries additional approvals including VdS.
