Relay Base Ec2 Series Kidde
SKU KD-KC2-RB
- Fast shipping from four branches
- 30-day returns on unopened products
The KC2-RB relay base adds auxiliary relay functionality underneath any KC2 series detector head, so a single conventional loop can also drive a fan shutdown, damper, or door closer directly off the detector's alarm state, without a separate control module.
Why installers reach for it
- Built-in auxiliary relay: contacts change state automatically the moment the connected detector goes into alarm.
- 4-inch, 4-terminal base: mounts to standard North American electrical boxes without an adapter.
- Shares detector diagnostics: works with any KC2-OS, KC2-OSH, or KC2-H head - no separate wiring scheme to remember per detector type.
Compatibility
Compatible with the full KC2 series head lineup (KC2-OS, KC2-OSH, KC2-H). A GSA-TS trim skirt is available separately if a finished trim ring is wanted around the base.
