Why would I need additional smoke detectors tied into my security system?

The battery operated smoke detectors installed in many homes is a simple life safety device. It has a local siren built into the detector that ensures no one will be trapped in your house during a real fire. A smoke detector that is tied into your burglar system is meant to add a second layer of protection in the event no one is home when the smoke detector is activated. The control panel will send the alarm signal as a fire alarm and the Derby city operator will then dispatch the fire department instead of the police department with the intention of saving your property from damage.
