12 FireForce 8 Installation & Operation Manual P/N 52257:B 09/27/2006
Installation Function of Input/Output Connections
2.3.4 Earth Ground
Connect to Earth Ground on the Power Supply module.
2.3.5 Trouble Relay
The common trouble relay is a normally energized Form C relay that transfers when the
FIREFORCE 8 detects a trouble condition. The contacts are rated for 2 amps @ 30VDC with a
power factor of 0.6 or higher.
2.3.6 Power Fail
The Power Fail relay is a normally energized Form C relay that transfers when a power failure or
brown out condition exists. The contacts are rated for 2 amps @ 30VDC with a power factor of 0.6
or higher.
2.3.7 Extender Output Circuit Wiring (Power Limited)
The FIREFORCE 8 Notification Appliance Circuit outputs can provide up to 3.0 Amps (power
limited) of 24 VDC each (total panel output is limited to 8 Amps). The outputs can be arranged as 4
Style Y (Class B), 2 Style Z (Class A) or 1 Style Z and 2 Style Y circuits. The EOL resistor value
for Style Y wiring is 3.9K ohms unless a reference resistor of a different value is used. Terminals
(n) L1 and (n) L2 are connections for style Y (Class B) wiring These designations are preceded by
the circuit number (n). When Style Z (Class A) wiring is used, terminal 1L1 will return to terminal
2L1 and terminal 1L2 will return to terminal 2L2, likewise, terminal 3L1 will return to terminal
4L1 and terminal 3L2 will return to terminal 4L2 for the second Class A circuit. Terminal L1
switches negative and terminal L2 switches positive during alarm condition. Either pair of
circuits can be designated Class A or Class B independently of the other pair.
