FCI FC-72 Series - Notification Appliance Circuits; Circuit Overview and Modules; Class A, Style Z Wiring

7.0 NOTIFICATION APPLIANCE CIRCUITS
The voltage on these circuits is 24 VDC (nominal). Connect only the UL Listed notification appliances shown
in FCI Addendum, P/N 9000-0427 to these circuits. Follow the installation instructions furnished with each
appliance.
The BMFC contains two notification appliance circuits, each rated at 1.75 amps, which operate only in unison.
Terminals 6, 7, 8, and 9 are for Circuit 1, and Terminals 10, 11, 12, and 13 are for Circuit 2. Each circuit is
individually protected and supervised for opens, grounds and shorts.
The output of these circuits is controlled through a notification appliance circuit module. There are four
standard modules that can be used with the FC-72 notification appliance circuits.
• BCM-6, Bell Card Module - Provides a continuous, non-coded output on the notification
appliance circuits.
• TCM-6, Temporal Coder Module - Provides a Temporal Pattern Emergency Evacuation Signal per ANSI
S3.41
• BMC-6, Master Coder Module - Provides an adjustable on-off duty cycle (march time pattern).
• CCM-6, Common Coder Module - Provides a variety of common coded signals, programmable
in the field.
The output parameters of the notification appliance circuits are as follows:
Voltage 24 VDC (nom.)
Max. ripple voltage .071 VAC (RMS)
Supervisory current .0017 amp.
Alarm Current 1.75 amp.
Power Limited
Supervised
Each notification appliance circuit module has a yellow LED which indicates the following trouble conditions:
• An open in the notification appliance circuit wiring.
• An open in the Signal Relay (K3) coil.
• An open overload device in either notification appliance circuit.
