3HAC11266-1 Output module

The HAC11266-1 output module is a product of ABB and is commonly used in fire alarm and control systems.

The main functions of the output module include:

Fire broadcast switch: Switch between normal broadcast and fire broadcast. When a fire or other emergency occurs, the module is able to quickly switch the broadcast system from normal mode to fire mode to broadcast emergency evacuation instructions or other relevant information.
Bus communication: The module communicates with the fire alarm controller through the bus, receives the instructions from the controller, and performs the corresponding operations according to the instructions.
Power monitoring: The output module can detect the status of the power bus, including power failure, to ensure the normal operation of the system.

Fault detection: The module can detect whether there is a fault in the input and output lines, such as short circuit, open circuit, etc., and send a fault signal to the fire alarm controller when the fault is detected.
Output control: According to the received instructions, the module can control the output of related equipment, such as starting the alarm bell, cutting off the non-fire power supply, etc.
Logical judgment: The embedded microprocessor in the module can make logical judgment on the input signal and perform the corresponding operation according to the preset logical relationship.
Status indicator: The module is usually equipped with a status indicator, which is used to display the working status and fault status of the module, so that users can understand the system status.
Scalability: Output modules can often be used in conjunction with other modules (such as input modules, relay modules, etc.) to build more complex fire alarm and control systems.
