FireAll™ solves a very significant problem in the ever tightening economy. All too often life saving fire alarm codes cannot be implemented into existing homes because of the expense. The inability to afford such an update can, and most assuredly, does cost lives. The FireAll™ system represents the least expensive meansby which Fire/Smoke/CO alarms can be interconnected, and therefore, puts that capability into the hands of families that cannot afford the cost of the conventional methods of manually interconnecting their alarms in an existing home.
Interoperability of Smoke and Carbon Monoxide alarms in a residential dwelling is the best protection for early warning and the saving of lives. Radio Wireless Alarms and FireAll™ both offer the better options to achieve that protection for existing homes, however the Radio Wireless Alarms have many more limitations, and Radio Wireless Alarms cannot be as dependable as FireAll™ during life threatening fires. FireAll™ is demonstrably the best add-on interconnection protection in existing homes.
FireAll™ works with virtually any Smoke and Carbon Monoxide alarm available today. It’s as simple to install as a Radio Wireless Alarm, however, unlike Radio Wireless Alarms, the FireAll™ system does not use high frequency waves transmitted through the air, but employs a far more reliable method of using lower frequency signals that are injected onto the power lines that run within the entire length and breadth of an existing home. This time tested method of communications greatly reduces the interference that plagues Radio Wireless Alarms.
In the real world, both Radio Wireless Alarm systems and FireAll™ systems have to deal with electromagnetic interference due to magnetic fields and noise from devices such as televisions, computers, Microwave ovens, motors, aquariums, lighting systems, fluorescent lights, and a host of other electrical devices and equipment. Radio Wireless Alarms are affected by the radiated magnetic fields of nearby equipment, whose frequency content can fall within the range of the bandwidth of the radio receiver, causing that noise to affect its operation; just as lightening affects radio and television reception.
A significant problem is that Radio Wireless Alarms have to also overcome interference from all the radio signals that come from most of today's new electronic devices: audio and security systems, amateur radios, phones, game stations etc. It seems that everything today, and in the future, is moving toward being wireless, and could potentially add major sources of conflicts with other wireless devices.
The FireAll™ system works by utilizing lower frequency electronic signals that are conducted onto all the power wires within a structure such as a home. Interference to the FireAll™ system, and the resulting potential for interconnection failure, is greatly reduced by the implementation of a narrow band crystal Surface Acoustic Wave, (SAW), filter that is used to reject any other frequency that may exist on the power line, while selecting only the specific range of frequencies used to communicate an alarm condition.
The FireAll™ system does not suffer from the same Radio Wireless Alarms signal degradation problem which occurs because objects (like floors, walls and ceilings) absorb and scatter the radio signals. Once wireless smoke alarms are installed, they should be tested weekly to determinewhether there are any physical sources of interference preventing communication or that the radio paths have not been disrupted by simply moving furniture or by renovations. Additionally, in older structures, Lead in paints before 1970, (even in small amounts), is a notorious barrier to wireless signals.
The most compelling reason why the FireAll™ transceiver system is a better choice than the Radio Wireless Alarm is presented within the studies as attached. These studies clearly show that the very things from which life must be protected, specifically fire and smoke, can be the very thing that degrades the radio signals used by Wireless Alarms and disrupts their ability to interconnect.
Lastly, after 7-10 years all alarms must be replaced as they approach their end of life; however, the FireAll™ power line interconnect system is a one-time installation. When the time comes to update, the only thing required is the replacement of the low cost alarm attached to the FireAll™ transceiver system.
