Signature Series

Signature Series detectors offer true multisensor technology and exquisite reliability that virtually does away with false alarms. They accomplish this by means of an on-board microprocessor that constantly monitors the state of its sensors. Using a sophisticated algorithm, the microprocessor effectively distinguishes between a legitimate change of state and a non-threatening situation that would otherwise lead to a false alarm.

What's more, true multisensor technology means that a single device can perform optimally under a wider range of conditions than any single-sensor detector. Photoelectric and ion detectors see smoke, but not all fires produce it. Heat detectors, on the other hand, spot temperature changes, but these aren't always an indicator of a life-threatening event. Multisensor devices, however, collect data on several different environmental parameters at the same time, and then weigh the results to determine whether an alarm should be sent to the control panel.

Multisensor or not, all Signature detectors feature analog technology. This allows them to gather information continuously concerning the state of their sensors and track the results over time. As detectors become dirty, the on-board microprocessor makes minute adjustments to the alarm threshold, thus avoiding false alarms. And when the threshold approaches the point where the device sensitivity could become compromised, the detector automatically sends a message to the control panel indicating that it's time for a cleaning.
