Wireless Fire Alarm Systems

Among all the security equipment for homes and offices, fire alarm systems are one of the most important. These kinds of equipment are known to save lives and in fact, commercial areas are required to go through a Fire Risk Assessment to determine the requirements of these systems.

With advancements in technology, traditional fire alarm systems are now replaced with their wireless counterparts as they bring in many advantages. The most significant benefit of a wireless fire alarm system over a hard-wired model is that they do not need any wiring. As a result, they are faster, cheaper and easier to install. You’ll not be required to drill any holes, and none of your wallpaper will be damaged for concealing the wires. Wired fire alarm systems’ installation can be described as quite a disruptive process. On the other hand, wireless systems can be installed easily without causing a lot of disruption.

Another main benefit of wireless systems is their fire resistance. For instance, if there is a wire in which the cables of a wired fire alarm system are damaged before the fire is detected, then there can be a considerable delay in fire detection. This problem can be successfully eliminated by installing a wireless alarm system.

If you are planning to buy a wireless fire alarm system, we’ve created a list of some of the best models to make the buying process easier and quicker. Understand the requirements of the location where you want to install these systems and then go through features of all the below-mentioned systems to make an informed buying decision.

As the detector doesn’t need any electrical connection, you can easily install it in places which are not wired to the electrical setup. It is also an exceptional choice if you have an older home which is not configured for installing traditional hardwired detectors. One major drawback of this unit is that it doesn’t feature photoelectric sensors, which are known to do an excellent job of detecting smoldering fires; i.e. the fires which are not yet ignited. Thus, it is recommended that you should use this detector along with photoelectric sensors.

Also, the detector cannot be interconnected with other detectors. As a result, only the sensor which is exposed to CO or smoke will activate. This can be a matter of concern if you have installed this detector at places like a basement, garage, etc. as you might not be able to hear when it goes off.

If the Wi-Fi smoke detector is tripped, the unit features a single button on the front which can be used to deactivate it. You can use this same button to test the fire alarm. When its battery is low, it’ll make a small chirp in every one minute, and it also features LED light which will start flashing. Moreover, the voice alarm will also inform if the battery is running low. This Kidde fire alarm comes with a 10-years warranty, and you can contact its support staff through email and telephone.

    Hi Casey,

    Thanks for participating on our pages about wireless fire alarm systems at albertafire.com. I just want to clarify that the items you are discussing are called wireless smoke alarms. A wireless fire alarm system would be a system that includes pull stations, smoke detectors, heat detectors and audible devices along with a control panel at the front door. These fire alarm systems are used to protect larger buildings and are designed to help the fire department locate the fire quicker as well as warning the occupants of the building to a fire situation.

    Thank you,
    Randy Brown
