Fire Alarm FAQs

There is probably an issue on the panel. Contact Koorsen, and a fire alarm technician will diagnose and fix the problem leaving you with a working fire alarm that isn’t beeping.

Typically, yes, depending upon occupancy, AHJ, and your insurance company requirements. Very rarely is there a situation when a fire alarm doesn’t require monitoring by a central station.

This is determined by your local AHJ, but it is recommended for proper notification within your building if a fire occurs. A fire sprinkler system is designed to save the property, while a fire alarm is designed to save lives.

Per the NFPA, your fire alarm needs to be inspected by a certified technician once per year. However, some insurance companies require inspections twice a year.

INITIATING DEVICES

Manual Initiating Devices

Pull Station:

Usually wall-mounted, when a person pulls the handle, the fire alarm is activated.

Break Glass Station:

Similar to a pull station but require person to break glass cover before activating the fire alarm.

Automatic Initiating Devices

Smoke Detectors:

A device that senses smoke and sends a signal to the fire alarm panel.

Heat Detectors:

A device that senses abnormally high temps and sends a signal to the fire alarm panel.

Duct Detectors:

A smoke detector device that is installed in HVAC ducts.

Beam Detectors:

A device that detects smoke across large areas using a projected beam of light.

Tamper Switches:

A mechanical and electrical device connected to a sprinkler valve that sends a signal to the fire alarm panel if the valve is partially or fully closed.

Fire Sprinkler Water Flow Switches:

A device that detects movement of water in a fire sprinkler pipe.

CONTROL PANEL

The fire alarm control panel is the brain of the fire protection system that monitors all initiating devices and activates notification devices when there’s a fire so everyone in the building can evacuate safely and the fire department can respond quickly.

NOTIFICATION DEVICES

Strobe:

When the fire alarm system is activated via an initiating device, the strobe, a flashing light, is activated, letting people know to evacuate. Strobes are especially important for those who are hard of hearing or deaf.

Speaker:

In fire alarm systems that use a voice evacuation system, a speaker is used.

Speaker Strobe:

A combination of a speaker and a strobe that is used in a voice evacuation system.

Horn Strobe:

Unlike a speaker strobe, a horn strobe emits a loud alert sound along with the flashing strobe light.

BATTERY BACKUP

In case of a power outage, a battery backup powers the fire alarm system so that it can continue to operate and monitor for fires.

ANNUNCIATOR

In case of a power outage, a battery backup powers the fire alarm system so that it can continue to operate and monitor for fires.

DOOR HOLDERS / CLOSERS

In the event of a fire, a door closer/holder will close the fire doors in a building to limit the spread of the fire and smoke.
