When utilizing the UPS-PFI (or any power supply with a 12V battery back-up),
locate it in the immediate vicinity of the PARC-3(s) to minimize the voltage drop
between supply and PARC-3. The distance between the UPS-PFI and its plug-in trans
former is less critical, but should be within 100 feet. The minimum recommended
wiring size for PARC-3 power connections is 18 AWG. A single UPS-PFI can power
multiple PARC-3’s if:
(a)
PARC-3’s are grouped together in one location
(b)
Total combined PARC-3 and 03RM current load is less than 1.2 Amp rating
(c)
Battery capacity is sufficient to meet minimum back-up requirement for
total combined load.
The following chart is provided to assist you in determining the total current load of each
PARC-3:
PARC-3 alone ........................................................................................... .035 Amps
No. __________ 03RM and 03RM/WP ......... X .040 = _________ Amps
No. __________ 03RM/IV ............................. X .120 = _________ Amps
Total current load per PARC-3 ..................................... = ___________ Amps
The AC voltage status at the UPS-PFI can be monitored at the Central Control by connecting
the UPS-PFI’s Normally Closed contact to the PARC-3’s Auxiliary Tamper input. If AC power is
lost at the UPS-PFI location, the Central Control will indicate a tamper condition on all zones
associated with that PARC-3. Meanwhile, the battery back-up will maintain system operation
until AC power is restored.
