Trouble Reporting
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.
