Section 4: Trouble Supervision
4.1 Supervised Functions and Field Wiring
• Field-wiring fault (short or open) on the NAC outputs of the power supply
• AC failure or brownout at the power supply
• Battery failure (no battery or battery voltage less than 20.5 VDC) condition at the power supply
• Battery charger failure on the power supply
• Ground fault condition
• +/- Reference Resistor
4.2 Trouble Reporting
4.2.1 Normal/Standby
NOTE: The trouble contacts AC FAIL and TROUBLE on TB2 and initiating device inputs SIGNAL1 and SIGNAL2 on TB3 are not
supervised by the HPFF8, but are used for supervision of the HPFF8 by the FACP.

1. No transfer and COMM & N/C are shorted.
2. The shorted contacts of COMM & N/C transfer to COM & N/O.
3. A battery fail indication can also occur if there was an AC failure within the first 24 hours after initial power-up and the battery voltage had been discharged to a
voltage between 20.5- 26.5 VDC. The BATT TRBL battery trouble LED may illuminate steady, after a certain delay during charging, to indicate the battery was
discharged and may not support a full alarm load. The delay is based on operational conditions (time remaining in the first 24 hours, time in stand-by, and time in
alarm) and will extinguish if the battery charging has time to reach its float voltage.
