Bosch DS939 PIR Ceiling Mount Sensor

Bosch Security DS939 PIR Ceiling Mount is a cutting-edge panoramic detector designed for comprehensive surveillance and security needs. With an impressive 360-degree coverage and a detection range of up to 21 meters (70 feet) in diameter, it is ideal for large commercial spaces where safety is a priority. This detector operates efficiently at ceiling heights of up to 7.6 meters (25 feet), ensuring thorough monitoring across expansive areas. The DS939 features First Step Processing (FSP), enabling a virtually instantaneous response to human targets while maintaining high immunity to false alarms from other sources. Its high-efficiency LED and light-pipe system provide clear walk test indications visible from any angle and height, simplifying installation and maintenance. An alarm memory feature allows the detector to latch the alarm LED, facilitating quick response during emergencies. Additionally, the remote LED walk-test control enables users to activate or deactivate the LED through a switched input without needing direct access to the detector. Operating on a voltage range of 9 to 15 VDC, the DS939 requires a standby current of 12 mA and 39 mA in alarm mode. With its robust features and reliable performance, the Bosch Security DS939 is an essential component for enhancing security in commercial environments.
