The 2452THS-15/75-R is a 2400 Series fire alarm horn-strobe with temporal pattern output, rated 15/75 candela and operating at 24V DC in a red housing. It delivers audible and visible notification from one appliance, cutting device count and NAC circuit load against separate horns and strobes.
Built for the commercial fire installer
The 15/75 candela dual rating means one part number covers both the standard 15 cd coverage case and the 75 cd requirement where higher intensity is called for, so a late change to a coverage calculation does not become a re-order. Combining horn and strobe means one backbox, one set of terminations, and one device to test at acceptance.
Temporal output meets the Code 3 evacuation signal requirement without a separate coder at the panel. Red is the standard finish for fire notification in commercial occupancies.
Key features
- Combined horn and strobe: audible and visible notification from a single appliance
- 15/75 candela rating: covers both standard and higher-intensity coverage from one part
- Temporal pattern output: Code 3 evacuation signalling
- 24V DC operation
- Red housing
System requirements
Wires to a notification appliance circuit on a compatible fire alarm control panel. Confirm the selected candela setting satisfies the coverage requirement for the space, and verify total NAC load against panel or booster capacity before specifying.
