The LSRA-SB gives installers a clean surface-mount option for the Kidde R-Series remote annunciator when a recessed electrical box isn't available. White-finished to match the annunciator face, it's the straightforward solution for retrofit jobs, exposed-conduit runs, and finished walls where cutting in isn't practical.

Built for the retrofit installer

R-Series remote annunciators normally mount on a standard 4-inch square electrical box with the included mounting ring. When the job calls for surface mounting instead, the LSRA-SB provides the back box without requiring wall modifications. Compatible with R-Series LCD and LED annunciator models used on Kidde FX-64, FX-1000, VS1, VS4, and EVOLVE fire alarm control panels.

Key features

  • Surface mount design: wall-mounts the R-Series annunciator where recessed boxes aren't available
  • White finish: matches the R-Series annunciator face for a clean, professional appearance
  • Retrofit-friendly: no wall cutting required for exposed-conduit and surface-wired installations
  • R-Series compatible: works with K-RLCD-2, K-RLCD-C-2, K-RLED-C-2, and K-RLED24-2 annunciator models

What you need to know

Sold as an accessory only - the R-Series annunciator is ordered separately. For multi-position surface mounting (annunciator plus expanders), see the RA-ENC locking steel enclosures. Confirm wiring entry points and conduit knockouts against the install location before specifying.

FAQs

Does the LSRA-SB include the annunciator?
No. The LSRA-SB is the surface mount back box only. Order the R-Series annunciator separately (K-RLCD-2 for LCD, K-RLED-C-2 for LED with common controls, etc.).
What annunciator models fit this back box?
Compatible with all Kidde R-Series remote annunciator models: K-RLCD-2, K-RLCD-C-2, K-RLED-C-2, and K-RLED24-2.
Can this hold an annunciator and expanders together?
No. The LSRA-SB is a single-position back box. For multi-position surface mounting (annunciator plus one or two expanders), use the RA-ENC2 (two-position) or RA-ENC3 (three-position) locking steel enclosures.
What panels work with the R-Series annunciators?
R-Series remote annunciators are compatible with Kidde FX-64, FX-1000, VS1, VS4, and EVOLVE fire alarm control panels. Check the R-Series spec sheet in the Documents tab for full panel compatibility details.
