Question: What is the Spread Spectrum Horn Tone?

Answer: The Spread Spectrum Horn Tone is a lower and varying horn frequency that sweeps through the 2200 – 3400 Hz range. As we age we lose the capability of hearing higher frequencies. This lower frequency and sweeping tone make it easier for the elderly with normal age related hearing loss to better hear the horn as compared to a standard horn. This is an important feature to discuss with customers as the overall population is getting older as the

Baby Boomer’s population segment moves into their 50’s, 60’s and 70’s. The first US Baby Boomers will turn 65 in 2011. (The baby boom refers to people born in the post-World War II period from 1946 through 1964). This market potential is already being targeted by builders as evidenced by the increase in the development of more “Over 55” communities. American’s 55 and older will head 40% of the nation’s households by 2012. No other alarm manufacturer has recognized this potential and has this feature to date.

Question: How can First Alert® OneLink® alarms be relevant for contractors who have existing home additions projects?

Answer: When dealing with new construction for existing home additions, the First Alert® OneLink® “Bridge” unit (SA520B) is a perfect solution. It is often difficult to connect to the existing alarm circuit when dealing with home additions. Concrete, steel, laminated beams, etc. are blocking easy access. Building codes state that the alarms must be hardwired for power, but do not have to be hardwired for interconnect. Therefore, the SA520B can be used in the new addition, where power can be obtained locally from a lighting or outlet circuit. In the existing part of the home, just replace one of the existing hardwired units with the SA520. Link the two alarms to “bridge” the old and the new sections.

**Interconnected alarms provide added warning as compared to single alarms.
