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.
4.
Battery Charger disabled during alarm.
4.2.1 TB2: AC FAIL Contacts
TB2's AC FAIL contacts are not supervised by the HPFF power supply, but will be supervised by
the FACP. The normally shorted COMM and N/C contacts will transfer to the COMM and N/O
contacts being shorted, only when an AC failure occurs. The transfer always occurs immediately
and will not be delayed even if DIP switch 7 is in the ON position. These contacts should be used
for local reporting of an AC failure for compliance of UL 864 9
4.2.2 TB2: TROUBLE Contacts
TB2's TROUBLE contacts are not supervised by the HPFF power supply, but will be supervised by
the FACP. The normally shorted COMM and N/C contacts will transfer to the COMM and N/O
contacts being shorted when a fault condition occurs. The transfer will not be delayed except if the
fault is an AC failure and DIP switch 7 is in the ON position. The transfer will be delayed for 2
hours in this case. These contacts should be used for delayed remote reporting of an AC failure for
compliance of UL 864 9
4.2.3 TB3: Initiating Device Inputs SIGNAL 1 and SIGNAL 2
TB3's alarm SIGNAL 1 and SIGNAL 2 inputs are not supervised by the HPFF power supply. They
will be supervised by the FACP or initiating device. The four connections +IN, –IN, +OUT, and –
OUT are used to connect either from a two-wire/Class B (Style Y) NAC with an end-of-line
resistor (ELR) or a four-wire/Class A (Style Z) NAC.
