Figure 42: D9412GV4/D7412GV4 v2.00 (and higher) Input Points and Peripheral Devices
(D125B, D129, D130) System Wiring
1 - (Optional): For 24 V applications use a UL 1481
listed, regulated, power-limited 24 VDC power
supply with a D130 Relay Module. Refer to the
D130 Installation Instructions (P/N: F01U072455)
for correct wiring requirements.
2 - D130 Relay Module
3 - D125B Powered Loop Interface Module
4 - To UL Listed two-wire smoke detectors with a fire
rated EOL resistor. Refer to Two-Wire Smoke
Detectors section in the Approved Applications
chapter in the CONTROL PANELS
(D9412GV4/D7412GV4 V2.03) Installation and
System Reference Guide (P/N: F01U265457) for
a listing of compatible two-wire smoke detectors.
5 - 1k Ω EOL resistor (P/N: F01U033966): For
typical alarm applications.
6 - D129 Dual Class A Initiation Circuit Module:
Provides optional Waterflow Alarm Retard
feature. Not suitable for two-wire smoke
detectors.
For D129, use zero retard except for waterflow devices.
All external connections except Terminal 5 (battery positive) are power limited.
