1 - (Optional): For 24 V applications, use a UL Listed 24 VDC Power Supply with a D130 Relay Module. Refer to the
D130 Operation and Installation Guide (P/N: 74-06262-000) for correct wiring requirements.
2 - To UL Listed two-wire smoke detectors. Refer to the 9000/9000G Series Technical Service Note: Smoke
Detector Compatibility (P/N: 33284) for a listing of compatible two-wire smoke detectors.
3 - P105F, 1 k
Ω EOLR (P/N: 15-03130-004): Suitable for un-powered initiating and supervisory devices such as
pull stations, heat sensors, and valve tampers.
4 - P105BL, 1 k
Ω EOLR (P/N: 15-03130-004): For typical burglar alarm applications.
5 - D129 provides optional Waterflow Retard feature. Not suitable for two-wire smoke detectors.
(Note: Use Zero Retard except for waterflow devices.)
All external connections except Terminal 5 (battery positive) are inherently power limited.
