2 Overview
The 2004-9101 is a conventional fire alarm control unit (FACU). The system includes four Class B initiating device circuits (IDCs) and one
notification appliance circuit (NAC). You can wire the NAC with Class A or Class B wiring.
Use the built in digital alarm communications transmitter (DACT) for remote station or central station monitoring.
The 2004-9101 control unit uses audible and visible indications during alarm, supervisory, or trouble conditions. If any of these conditions
occur, the system activates the applicable notification appliances, respective LEDs, and the piezo. The indications continue until an
operator acknowledges the condition.
