Vds Lpcb Approval 10years Battery Sealed in Linkable Smoke Alarm

1. Brief introduction
KD-122LE Wireless Interconnectable Smoke Alarm is a portable, photoelectric smoke alarm with low power consumption. Internal precise analog circuit and digital circuit make the detection work more stable and reliable. It has interconnection function using radio frequency link, which means when one unit makes alarm, other interconnected units within the interlink range will alarm at the same time.
