The System Sensor 2824 is a 24-volt photoelectric smoke detector. This device offers a unique sensing chamber with built-in test capability. The 2824 is suitable for both residential and commercial applications.
The System Sensor 2824 detectors are designed to be more responsive to a broader range of fires and at the same time offer maximum stability. They’re compact, attractive, and easy to install. These detectors operate on the light scattering principle and feature a unique photo optic sensing chamber that provides good smoke entry while minimizing the effects of ambient light. Its carefully designed geometry maximizes signal strength and signal-to-noise ratio. This sensing chamber is more responsive to fast flaming fires than the chambers used in most competitive units.
It can, therefore, be set less sensitive and further from the threshold of alarm than most competitive detectors. This combination of a high signal-to-noise ratio and stable sensitivity setting gives the detector remarkable stability over a wide range of environmental conditions.
The detector also has a custom integrated circuit that uses signal processing for alarm verification. In standby mode, its infrared LED is design to pulse once every eight-second, but when smoke is detect, this sampling rate accelerates to one per second. Two successive positive samplings are require before the detector can alarm, and this significantly increases its immunity to nuisance alarms.
