2.3.2 Battery Power
The batteries must be sealed lead acid type. Before con-
necting the batteries to the FACP, make certain that the
interconnect cable between the batteries is not connected.
Do not connect the interconnect cable until the system is
completely installed. Observe polarity when connecting
the batteries. Connect the battery cable to J9 on the main
circuit board. Refer to "Power Supply Calculations" on
page 159, for calculation of the correct battery rating.
WARNING: RISK OF PERSONAL INJURY
!
BATTERY CONTAINS SULFURIC ACID WHICH CAN CAUSE SEVERE BURNS TO THE SKIN
AND EYES AND CAN DESTROY FABRICS. IF CONTACT IS MADE WITH SULFURIC ACID,
IMMEDIATELY FLUSH THE SKIN OR EYES WITH WATER FOR 15 MINUTES AND SEEK
IMMEDIATE MEDICAL ATTENTION.
2.3.3 Special Application DC Power Output Connection
All Special Application DC power outputs are power-limited (refer to"UL Power-limited Wiring
Requirements" on page 36).
Power-limited Non-resettable or Resettable Power
1.0 amperes max., 24 VDC nominal filtered, non-
resettable or resettable power can be drawn from TB1
Terminals 1(+) and 2(-)
JP4 is used to configure TB1,
Terminals 1 & 2 for:
• Resettable Power - jumper pins
2 & 3 of JP4
• Nonresettable Power - jumper
pins 1 & 2 of JP4 as shown
Figure 2.6 Special Application Power Outputs - 24 VDC
2.4 Relays
The FACP provides two programmable Form-C relays and one fixed fail-safe Form-C trouble
relay, all with contacts rated for 2.0 amps @ 30 VDC (resistive) or 0.5 amps @ 30 VAC (resistive).
Note that relay connections may be power-limited or nonpower-limited, provided that 0.25" spac-
ing is maintained between conductors of power-limited and nonpower-limited circuits. Refer to
UL Power-limited wiring requirements.
Note that the programmable relay
labeled as Relay 1 is factory default
programmed as Alarm and
programmable Relay 3 is factory default
programmed as Supervisory.
The relay labeled Relay 2 is fixed as a
Trouble relay and cannot be changed.
It is a fail-safe relay which will transfer
on any trouble or total power failure.
