The GRI 4701-A is a Single Pole Double Throw (SPDT) switch designed for reliable contact monitoring in security and automation systems. Its 3-foot (0.9m) armored cable and adjustable gap up to 3 inches (7.6cm) make it suitable for applications where a standard magnetic contact is insufficient, such as monitoring large or irregularly shaped access points. This switch provides a definitive open/closed state signal, crucial for verifying the status of doors, windows, or equipment hatches.
This SPDT switch is designed for integration with any alarm panel, access control system, or automation controller that accepts standard dry contact inputs. It is compatible with systems requiring a normally open (NO) or normally closed (NC) configuration due to its dual-throw nature. The armored cable provides enhanced protection against tampering and physical damage, making it suitable for environments where wiring might be exposed.
The 3-foot armored cable allows for flexible mounting and routing, accommodating gaps up to 3 inches between the switch body and the actuator arm. Ensure the actuator arm is positioned to reliably engage the switch mechanism as the monitored access point opens or closes. The SPDT configuration allows for two distinct states to be wired to separate inputs if required by the control system, offering advanced status reporting.
