STS-22 GPS Satellite Time Sync

Synchronize all your intersections using a single GPS receiver module, regardless of traffic controller make.


The STS-22 maintains the accuracy of your equipment’s internal clocks and remains perfectly synchronized at all times, including after power outages. Indeed, it uses the GPS time signal to automatically readjust itself. This signal is perfectly stable and eliminates the risks of thermal drift deregulation. The module can be plugged into any standard NEMA or 170 detection cabinet and is equipped with a practical backlit multipurpose display that enables onsite configuration and status monitoring.

The STS-22 eliminates the cost of running underground cables as well as radio communication and clock resetting fees and minimizes maintenance costs. It’s an unbeatable economical solution!

Main characteristics

  • Transmission capacity of time AND date (day, month, year) through a serial link to any make of controller
  • Dual means of configuring the system and internal firmware: using the Windows software provided or the front-mounted multipurpose display
  • Optocoupler contact output to synchronize the clocks of older-generation controllers that are not equipped with a direct communication device
  • Operates in 120 VAC or 10-30 VDC mode depending on the cabinet’s supply voltage
  • Possibility of generating power outage reports
  • Discrete antenna that reduces the risks of degradation and interference during installation and improves overall appearance
