single NAC must not exceed 40, with a maximum loop
resistance of 120 Ω. For 12 V applications, the total
number of strobes must not exceed 12, with a
maximum loop resistance of 30 Ω.

Mounting Considerations
These horn strobes mount on a standard 4‑inch square
back box, a 4‑inch octagon back box, a single‑gang
back box, or a double‑gang back box.
Wiring Considerations
The input terminals on the universal mounting plate
accept solid wires between 12 AWG (2.3 mm) to
18 AWG (1.2 mm).
