Tower-Light: Metering System

towerlight antgroupThe TowerLight 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.

Total FCC compliance

Operation
After a calibration, the system continuously checks the current consumption as main parameters to define the alarm status for: flashing
fault, main power presence, beacon fault, 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

Benefits

  • Compact design
  • Easy installation

Technical specification

  • Power Supply: 9 ÷ 15 VDC
  • Input Current: 200 mA, 2.5 W

Outputs

  • On beacon lamp and/or flasher failure or user selectable hours of no activation
  • On side marker lamp failure, or user selectable hours of noactivation
  • If tower lights are off (day status, user selectable)

The general specifications can be changed without any notice.
Functionality can be achieved with a minimum effort: this is the secret of modern technology.
And this is also the result of uninterrupted development, where research and design push the competitive edge of technology.
ANT's remote control system is the result of this philosophy: "Garda System" embeds in a single product state-of-the-art technology, advanced features and easy of use”
