4. All circuits are power limited to NFPA 70 per NEC 760.
Each detector or group of detectors must use a two
wire circuit of at least 18 AWG thermoplastic fixture
wire enclosed in conduit, or 18 AWG limited energy
shielded cable without conduit, if permitted by local
building codes.
5. Total circuit resistance must not exceed 70 ohms, 40
ohms if relay bases are used.
