Typical Wiring
INITIATING CIRCUITS
Rated: 18.1–23.5 VDC, Unfiltered Full Wave Rectified
Supv: 9mA
Alarm: 275mA
1. Total zone initiating circuit resistance is 36 ohms max (9 ohms per line).
2. Unused (spare) zones must have an EOL device connected.
3. See individual detector for actual terminal connection numbers. Maximum
of 30 detectors (any combination of those listed on the table at the right)
are allowed per circuit. Also may use optional detector remote lamp or
detector relay as indicated on the applicable detector instructions.
4. Positive and negative ground fault impedance threshold
≤
40K ohms.
