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)
