fire alarm monitoring system
The National Fire Protection Agency recommend that people install combination alarms, that is, a combination of photoelectric and ionization technology. However few alarms combine both kinds of detection. Combination alarms rarely carry a built in carbon dioxide detector. Combination alarms run on AA batteries and cost around US$23 each. Most photoelectric smoke detectors run on AC power circuits meaning the users have to install the wirings around the house. Such smoke detectors also have a backup battery aside
from the 120 volt power it needs to function. Smoke detectors should be placed where smoke isn’t supposed to be. Avoid installing them in kitchens or rooms that have steams like saunas and bathrooms to prevent false alarms. Do not install smoke and carbon dioxide detector in breezy and ventilated areas like in
front of electric fans, air conditioners, windows and doors. They may pick up smoke that originated in other places or the fresh air might obscure the reading, preventing the device from setting off when it should. Install them on a high wall or in the ceiling because smoke and fire rises.
