SHIELD S-A4005 Low Power Relay Base

The SHIELD S-A4005 (Part Number: S-A4005) is an intelligent addressable detector mounting base manufactured by Shield, engineered with an integrated low-power auxiliary relay circuit. Designed to provide localized activation of secondary systems when its mounted detector enters an alarm state, the S-A4005 is ideal for interfacing directly with door retainers, air handling units, damper actuators, localized sounders, or security shutoff systems. Operating efficiently on minimal current drawn directly from the addressable loop, it eliminates the need for external power supplies or separate relay output modules for single-point control. Housed in a durable, flame-retardant white ABS enclosure, the base features clear screw terminal blocks for ease of wiring and mounts securely to standard ceiling backboxes.
