These units are designed to detect an intruder and activate
an alarm control panel. Being only a part of a complete
system, we cannot accept responsibility for any damages
or other consequences resulting from an intrusion.
These products conform to the EMC Directive 2004/108/EC.
Specifications and design are subject to change without prior notice.
* The value is based on the condition that it is used within the
ambient temperature range of 20 to 25°C. (LSH-20 x2 pcs)
** Using batteries other than those recommended may shorten the battery life.
