X-Sense XP0J-iA Smart Hardwired Smoke & CO Alarm

Photoelectric sensor, 1.02 to 1.66% obs/ft sensitivity

Electrochemical sensor, alarming in 4 to 15 minutes at 400 ppm and 10 to 50 minutes at 150 ppm

85 dB at 10 ft (3 m), a 3.2 kHz pulsing alarm paired with spoken alerts

The alarm monitors its own smoke and CO sensors and announces a fault, a contaminated smoke chamber or end of life on its own; a full test can also be run remotely from the app with one tap

App push notification the moment smoke is detected, plus a voice alert naming the room

App notifications cover low battery, device fault and end of life

Connects straight to a 2.4 GHz network (2400 to 2483.5 MHz), with no base station: X-Sense states the model is incompatible with the SBS50 base station

Up to 18 alarms interconnect over the AC interconnect wire, with a maximum run of 1000 ft (300 m) between the first and last unit

Status is shown by a four colour LED indicator (red, green, yellow, blue), not a screen

X-Sense labels its Alexa compatible products explicitly (the STH thermometer hygrometers) and makes no such claim for its smoke and CO alarms; the user manual documents the X-Sense Home Security app as the only control path

The community X-Sense integration reads the cloud account through python-xsense, whose device map lists models by code (XS01-WX, SC07-MR, XP0A-MR, XH02-M and the rest) and does not include XP0J

The CSA certified products database lists only the X-Sense SBS0A Matter base station under X-Sense Innovations, not this alarm, and the model is not compatible with an X-Sense base station anyway
