In a typical home fire, occupants have just minutes to escape. And because smoke in one area may not reach a smoke alarm in another, the National Fire Protection Association (NFPA) Requires placement of at least one smoke alarm; on every level of the home (including basements), in every bedroom and outside each sleeping areas. The NFPA also requires interconnection of alarms to offer better whole-home protection than stand-alone alarms.
Over half the homes we go in, we find the smoke alarms are not working. The batters are missing and many times the alarms are missing altogether. Portable smoke detectors with just a regular battery are a problem. Good smoke detectors (like the one we install at Positively Electrical) come with a 10-year lithium-ion battery. In fact, The fire codes now requires sealed 10-year lithium-ion batteries in all smoke alarms. If you are a residential building landlord in Santa Barbara, a hard-wired 10 year photo electric smoke alarms, will give you less trouble with tenants abusing it or getting rid of the alarms altogether.
Positively Electrical installs Kidde smoke detector units in Santa Barbara which are photo-electric. They are not as sensitive to shower steam, cooking odors or tobacco smoke, minimizing the number of irritating false alarms.
To help make sure greatest protection authorities recommend both ionization and photoelectric smoke alarms. Because various types of fires can occur within the home; Ionization sensing alarms may detect invisible fire particles (associated with fast flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible fire particles (associated with slow smoldering fires) sooner than ionization alarms.
