The Kidde RF-SM-ACDC is a 120V AC hardwired smoke alarm that uses radio frequency wireless technology to expand or bridge existing interconnected alarm systems. Two universal adapters are included, allowing it to work with most existing Kidde interconnected hardwired systems. This model has been discontinued and replaced by the Kidde 20SAR.
What are the universal adapters included with the RF-SM-ACDC?
The RF-SM-ACDC includes two universal adapters that allow it to integrate with most existing Kidde hardwired interconnected alarm systems. These adapters bridge older interconnect protocols with the RF wireless system.
How does wireless interconnect work on the RF-SM-ACDC?
The RF-SM-ACDC uses radio frequency to transmit and receive alarm signals wirelessly. When any alarm in the interconnected system detects a hazard, all RF-compatible alarms sound simultaneously without interconnect wiring between units.
Is the RF-SM-ACDC still available?
No. The RF-SM-ACDC has been discontinued. Kidde recommends the 20SAR as the current replacement, offering DETECT-line photoelectric sensing and AA battery backup.
Does the RF-SM-ACDC have battery backup?
Yes. The RF-SM-ACDC includes a 9V battery backup for continued operation during power outages. Replace the battery annually or when the low battery chirp sounds.
What is the RF-SM-ACDC best used for?
The RF-SM-ACDC is designed to expand existing interconnected alarm coverage using wireless RF, eliminating the need to run interconnect wiring to additional rooms or floors in an existing home.
