The 2452THS-30-R pairs a piercing temporal horn with a 30 cd strobe in one wall-mounted appliance, covering restrooms, meeting rooms, lobbies, hallways, and other areas where both audible and visual notification are required.

Built for the commercial fire installer

The horn is field-configurable for steady or temporal tone and high (98 dBA) or low (94 dBA) output; when temporal output is selected, every horn on a common two-wire circuit self-synchronizes without an external control module. The strobe exceeds UL 1971 synchronization requirements (within 10 ms over two hours) when paired with a compatible sync source, and is fully compatible with Genesis signals on the same circuit. A single-screw mounting plate holds the device wired and hanging free for inspection before final fastening.

Key features

  • Self-synchronizing horn on temporal setting - no external module needed for audible sync
  • Adjustable output: steady or temporal tone, high (98 dBA) or low (94 dBA)
  • 30 cd strobe, UL 1971 and UL 1638 listed
  • Genesis-compatible strobe synchronization with an external control module
  • Field-changeable lens markings via optional LKW/LKC kits

System requirements

Strobe: 16-33 Vdc continuous. Horn: 16-33 Vdc or VFWR continuous. Flush-mounts to a North American 2-gang box (2-3/4" minimum) or 4" square box. Strobe synchronization requires a compatible source (EG1M-RM, GSA-CC1S, GSA-MCC1S, MIRBPS6A/10A, APS6A/10A).

FAQs

Do the horns synchronize without a special module?
Yes, for audible temporal synchronization - all horns on a common two-wire circuit self-synchronize. Strobe visual synchronization to full UL 1971 tolerance still requires a compatible sync source.
Can I select steady tone instead of temporal?
Yes. The horn is configured at installation for steady or temporal tone, and high or low output.
Can I change the lens wording later?
Yes. Optional LKW (wall) and LKC (ceiling) series lens kits snap on to change language or wording without replacing the device.
What box does this mount to?
A standard flush-mounted North American 2-gang electrical box (2-3/4" minimum) or a 4" square box; surface and outdoor boxes are also available.
