How It Works
The Seco-Larm E-931-S35RRQ functions by creating an invisible infrared beam between a transmitter and a reflector. When the beam is interrupted — whether by a person, vehicle, or object — the sensor sends a signal to trigger an alarm, door mechanism, or indicator light (depending on your setup).

Alerting you when a vehicle enters the driveway
Detecting motion near garage doors or gates
Providing perimeter protection for homes or businesses
Serving as a parking guide inside garages
