Putting the Innovation in Renovation

When it comes to alarm renovation and retrofit projects, choices have been limited. Installing battery operated alarms and sacrificing interconnectability or investing in the time and labor to retrofit hardwired alarms have been the only options available.* Until Now! BRK Wireless Interconnect alarms eliminate the need to pull wires through existing walls saving time, money and labor.


No matter what your renovation project, BRK Wireless Interconnect alarms provide a cost effective solution:


Home Addition Projects:

Using the BRK Wireless Interconnect hardwired "Bridge Unit" (SA520B), simply replace one hardwired alarm in the existing section and add one to the new section. Wireless technology saves time, material and labor to connect to the existing alarm circuit. Now add standard BRK hardwired alarms as required in the new section and other BRK Wireless Interconnect alarms in the old section to complete the alarm safety system and bring entire home up to code. All alarms, hardwired and battery, existing and new are now interconnected.


Retrofit Projects:

Property Owners, Facility Managers and Electrical Contractors can all benefit from installing BRK Wireless Interconnect alarms for existing retrofit projects. Saving $150 - $200** per alarm and increasing job turnaround 4X are key reasons to consider First Alert Wireless Interconnect alarms for all of your renovation projects.

Mesh Network Illustration

Mesh Network Communication

BRK Wireless Interconnect alarms operate on a "mesh network"; a 2-way communication format that sends, receives and then re-sends the alarm signals. If the initiating alarm signal is blocked from reaching one of the alarms, the mesh network communication reroutes and re-sends the signal via the other alarms as shown in the illustration. With competitive one-way wireless communication, only the initiating alarm sends a signal which may never be received, leaving the blocked alarm deadly silent.

**Note: Based on average retrofitting costs of time, material and labor to connect to existing alarm circuit, drywall repairs, painting, etc. Special cases that require conduit, wire mold, concrete drilling, etc. would add additional costs and increase savings.
