The GRI 4532CL is a miniature overhead door sensor designed to detect the open or closed state of a door or gate. It utilizes a Single Pole Double Throw (SPDT) switch, providing flexibility for normally open (NO) or normally closed (NC) configurations. The 24-inch armored cable offers protection against physical damage, making it suitable for environments where security and durability are paramount, such as commercial warehouses or industrial facilities. This sensor is intended for integration with alarm systems or access control panels to monitor door status.
This sensor is compatible with alarm control panels and access control systems that accept SPDT dry contact inputs. The M-15 magnet is designed for mounting on standard overhead door tracks. The included 4175 bracket facilitates installation on various door frame types. Specific system compatibility depends on the input configuration of the connected control panel.
The 24-inch armored cable provides a 24-inch reach from the mounting point to the sensor. Ensure the M-15 magnet and the sensor are aligned for proper operation when the door is in its closed position. The SPDT switch allows for flexible wiring to suit either normally open or normally closed alarm conditions. The 4175 bracket requires standard mounting hardware (not included) for secure attachment to the door frame or wall.
