Wireless Interconnected Smoke Alarm

1. Brief introduction

KD-122LA Wireless Interconnected Fire Detecting Alarm is a portable, photoelectric smoke alarm with low

power consumption. Internal precise analog circuit, digital circuit and wireless transmission circuit make the

detection work more stable and reliable. It has wireless interconnection function, which means when one unit

makes alarm, other interconnected units within the interlink range will alarm at the same time. This product

has small volume and the built-in large-capacity battery can provide service life of 10 years.(If used under WiFi

system, it is around 5years)
