What is an auxiliary fire alarm system?
Auxiliary Fire Alarm System: A system connected to a municipal fire alarm system for transmitting an alarm of fire to the public fire service communication center.
What is a Class 1 fire alarm system?
The Code states that remote-control circuits for safety-control equipment is to be classified as Class 1 if failure of the equipment to operate introduces a direct fire or life hazard. Similarly, fire alarm system wiring does not fall into this category because it does not introduce direct fire or life hazard.
What buildings require a fire alarm system?
If you have a high-rise building — which most codes define as any building that exceeds 75 feet in height above the street level — then most likely you must have a fire alarm system, along with specific communication systems for the fire department to use if the building needs to be evacuated.
Are carbon monoxide detectors required in Utah?

What are the three methods of transmitting fire alarm signals?
Fire – alarm signals may be transmitted to the fire department via telephone, two-way radio, master (city) box, or any other means of communication acceptable to the local fire officials.
Why fire alarm system is required?

How does an automatic fire alarm work?
Initiating devices detect a fire emergency and communicate it to the fire alarm control panel.

When one of these initiating devices is triggered, the control panel will go into an alarm state.
What is the difference between Class A and Class B wiring?
Class A wiring has 4 wires. Power is supplies from both directions one cut wire does not cause loss of function to a device on the circuit. Class B wiring has 2 wires. Power is fed from one direction with an end of line device present at the opposite end.
What is the difference between Class A and Class B fire alarm?
During a fire, in Class B wiring style, if a wire breaks, the devices beyond the break won’t communicate with the panel. In Class A wiring style, the panel can back-feed communication on the return loop, so most if not all devices still communicate. Class A Wiring will survive better than Class B Wiring.
What is a Class 2 circuit?
The NEC defines a Class 2 circuit as that portion of the wiring system between the load side of a Class 2 power source and the connected equipment. Due to its power limitations, a Class 2 circuit is considered safe from a fire initiation standpoint and provides acceptable protection from electrical shock.
Are smoke detectors required if you have sprinklers?
