That is a good question considering that the fire code requires smoke detectors in all dwelling units in Ontario. Our systems have the ability to monitor smoke and heat detectors and any existing system can have them added at any time. There are two major advantages to having monitored smoke detectors. Many home smoke detectors are powered by 120 Volt electrical power, that can fail because of an electrical fire. Our smoke detectors are powered from the alarm panel that is equipped with a standby battery – it will keep working in the event of a power failure. The second, and perhaps more important advantage is the assurance that the fire department will be notified if you have an emergency. Smoke and heat detector zones remain on guard even if your intrusion alarm is disarmed.
