Window Motion Sensor - Multiple Beam Sensors
The items on this page are Sensors ONLY for the professional installer / electrician / or person knowledgeable in low-voltage circuits
. Complete Entry Alert systems can be found on our website page: Entry Beam Systems
These sensors can be used to sense motion or passage through an "invisible wall". They can be used in hallways, entryways, in a fully open window or fully open garage door; you cannot step over these sensors. Most of these multi beam sensors need power and put out a Normally Open (NO) or Normally Closed (NC) NO/NC signal or a 12VDC signal to activate a circuit as simple as an alarm bell or alert chime when the "invisible wall" or "invisible barrier" is penetrated.
Multi Beam Sensors create an invisible wall or curtain of security sensors via multiple point to point (non-visible) sensors.
