Patented Simplex^® TrueAlarm^® analog detection systems provide the latest in early-warning fire detection technology. The addressable, high performance TrueAlarm sensors enable Simplex fire alarm systems to detect hostile smoke in its incipient stage, but without over-sensitivity that can generate false alarms.

Over two million TrueAlarm sensors have already been installed with Simplex systems, providing protection for a wide variety of Fortune 500 businesses as well as leading institutional and educational facilities. Each addressable sensor possesses a unique ID that identifies its location at the control panel.

With photoelectric sensitivity that can be set as precisely as 0.2 percent (per foot of smoke obscuration), TrueAlarm sensors remain the most sensitive spot-type smoke sensors on the market today. They can provide crucial additional minutes to summon fire services, evacuate occupants and activate suppression systems. Among the advanced TrueAlarm detector performance features are environmental compensation, automatic warnings when detectors need cleaning, and peak value logging. Unique to Simplex systems, peak value logging minimizes nuisance alarms by recognizing that different environments may require different sensitivity settings. Peak value logging permits the customer to set sensor sensitivity to coincide with the fire risk in the protected environment.
