The Kidde INT-T is a 24 VDC temporal fire alarm horn that delivers self-synchronized Code 3 signaling on standard NAC circuits. Mount it, wire it, and every horn on the circuit locks into the same temporal pattern automatically - no external sync modules, no extra wiring, no callbacks for out-of-phase units.
Built for the commercial installer
Self-synchronization is the install story here. On multi-horn circuits, every INT-T on the NAC syncs its temporal pattern with every other unit without additional hardware or programming. That cuts install time and eliminates the drift complaints that come with unsynchronized horns in hallways and stairwells. Standard wall mounting keeps the install straightforward.
Key features
- Self-synchronized temporal pattern: all horns on the circuit lock into Code 3 automatically, no sync module required
- 24 VDC operation: powers directly from the fire alarm panel NAC circuit
- Wall mount form factor: red housing for standard fire alarm installations
- Temporal Code 3 signaling: meets ANSI S3.41 evacuate pattern requirements per NFPA 72

What does self-synchronized mean on this horn?
All INT-T horns on the same NAC circuit automatically synchronize their temporal pulse pattern without external sync modules or additional wiring. Add units to the circuit and they lock into the same cadence on their own.
What signaling pattern does the INT-T produce?
Temporal Code 3 per ANSI S3.41 - the standard three-pulse evacuate pattern required by NFPA 72 for fire alarm notification.
Does this horn operate on 12 VDC?
No. The INT-T is rated for 24 VDC only. It connects to a standard 24 VDC NAC circuit from the fire alarm control panel.
Can I mix the INT-T with other notification appliances on the same NAC?
The INT-T self-synchronizes with other compatible Kidde self-synchronized notification appliances on the circuit. Verify device compatibility against your FACP manufacturer's listed device table.
