2 Overview
The 2050-9101 and 2250-9101 are addressable fire alarm control units (FACUs).
2050-9101 is a small one loop addressable control unit with the capacity of 50 addressable devices or points for each loop. You can wire
the loop using Class A or Class B wiring. The control unit supports two Notification Appliance Circuits (NACs). You can wire the NACs using
Class A or Class B wiring.
Whereas 2250-9101 is a comparatively big one loop addressable control unit with the capacity of 250 addressable devices or points for
each loop. You can wire the loop using Class A or Class B wiring. The control unit supports four Notification Appliance Circuits (NACs). You
can wire the NACs using Class A or Class B wiring.
Both control units support an internal or external gateway module for communication with the remote station or central station.
Both control units provide audible and visible indications during Fire alarm, Priority-2, supervisory, or trouble conditions. If any of these
conditions occur, the system activates the applicable notification appliances, respective LEDs, and the control unit piezo. The indications
continue until an operator acknowledges the condition.
Note: From this point on, both the 2250-9101 control unit and the 2250-9101 control unit are referred as 2250, unless stated otherwise.
NAC trouble configuration must be avoided for general announcement and must be limited to specific applications like notifying a security
person.
