The GRI 4613 is an armored cable switch set designed for securing curtain doors in commercial and industrial environments. This unit provides a reliable contact closure signal when the door is in its secured position, integrating with access control or alarm systems. Its armored cable construction protects wiring from tampering and physical damage, making it suitable for high-traffic areas. The 2-inch gap accommodation ensures flexibility during installation on various curtain door types. The model number 4613 signifies its specific configuration for these applications.
This switch set is designed for use with curtain doors that require a 2-inch gap for operation. It is compatible with standard security and access control systems that accept dry contact (SPDT) inputs. Specific system compatibility depends on the input requirements of the connected alarm panel or access control reader, but the SPDT (Single Pole Double Throw) configuration offers versatile wiring options for normally open (NO) or normally closed (NC) circuit configurations.
Installation requires mounting the switch and its corresponding actuator to the curtain door and its frame, ensuring the 2-inch gap is maintained when the door is closed. The armored cable should be securely fastened to prevent strain on the internal wiring. Wiring should be performed by a qualified technician, connecting the SPDT terminals to the appropriate inputs on the security system. Ensure proper strain relief is applied to the cable where it enters the switch housing and at the termination point.
