Towers Light
The Tower-Light is a microprocessor based system designed to monitor the status of obstruction lights, used on many broadcast and communication towers. The system will monitor up to eight beacon bulbs and eight marker bulbs: monitoring processing allows controlling all lamps from a single point, including flasher operation. All outputs are opto-isolated for lightning protection when connected to external remote site monitoring equipment. With all lights operating on the tower, the monitor automatically calibrates itself for the number of bulbs in the system.
The unit is specifically designed for broadcasters: great consideration especially for the fault tolerance and twilight sensor fault.
FEATURES
Total monitoring of beacon tower lighting systems
One key press auto-calibration
Individual alarm outputs for power supply, beacon
General alarm output for photocell and light
Easy to install - installs inside the transmitter building, even if the lighting control equipment is located at the tower
Insures total lighting compliance
Alarms for single bulb failure (marker and beacon), beacon flash rate or on/off ratio outside of FAA specifications and photocell failure.
