The SECO-LARM E-964-Q330Q Enforcer is a quad photobeam detector that is constructed with built-in laser beam alignment system for accurate and reliable positioning. The user can adjust until best position is achieved with the help of the built-in alignment strength indicator. False alarms due to external factors such as animals, leaves or others are minimized to the maximum by providing perfect perimeter security. With the beam strength increased by the lens optics, climatic factors such as rain, mist and snow are prevented from triggering false alarms.

The photobeam detector is suitable for both indoor and outdoor purpose, thanks to the weatherproof and sunlight-filtering body. Featuring the anti-frost system with built-in heater, the SECO-LARM E-964-Q330Q Enforcer photobeam detector can function effectively even in extreme conditions. It has automatic input power filtering with special noise rejection circuitry and interruption time adjustment for almost all situations. The SECO-LARM E-964-Q330Q Enforcer quad photobeam detector covers a maximum range of up to 330ft (100m) in outdoors and 660ft (200m) in indoors.
