Nexa sensor security system on windows/doors 3V
It is installed on doors and windows as a simple alarm system. The sensor responds to the status of the contacts - open / closed. When the magnetic plug is open, a signal is sent to the connected receiver, which lights up. When the magnetic plug is "closed", a trip signal is sent to the connected receiver. There is also the possibility of a timer to monitor the connection between the magnetic connector and the receiver.
Off timer: 2/4/8/10/15 and 20 minutes.
NB!!! Batteries included
