All design will be done as per the International Building Code(IBC) and National Fire Protection Association (NFPA).
Secure Your Building With
Our systems are equipped to detect heat, smoke, and carbon monoxide, ensuring you'll aways be aware of a problem in your building.
Our rapid design process is flexible and agile, and allows us to have turnaround times 50% faster than anyone else in the industry.
You can never be too prepared for an emergency. Our systems call the fire department for you, so they'll arrive as soon as possible.
Initiating devices activate the alarm system, as their name implies. These devices include smoke detectors, manual pull stations and sprinkler flow sensors. They typically use 2-wire or 4-wire circuits, and a 24 VDC power source. These devices are divided into zones, where each zone is connected to the control panel with each own circuit.
Initiating devices are connected in parallel, with ungrounded wires that are isolated from all metallic raceways. The connection polarity is critical for proper functioning, since they are direct current devices.
Indicating appliances complement the function of initiating devices, announcing that the alarm system has activated. Some examples of indicating appliances are horns, strobe lights, chimes and bells. Depending on the application, these devices may be weatherproof, or rated for hazardous locations.
The control panel contains the user interface, branch circuit connections, and all electronic components needed to operate the fire alarm system. Each alarm zone has a separate circuit board, allowing modifications and maintenance without affecting other zones. The control panel displays the system state, and a touchpad is provided for user inputs.
Fire protection engineers recommend installing the control panel in a staffed or centralized location. Some viable options are the building security headquarters, the telephone switchboard room, or a maintenance office. The control panel monitors the voltage and current on all zone circuits, detecting possible issues as soon as they occur.
Fire alarm systems also use auxiliary devices like LED remote annunciators, LED zone indicators, alarm silencing switches, and electromagnetic door holders.
