AP21TR, AP21TRDC
Compact Size:
2" x 2.5" x 4"

 The family of AP21's are single circuit, calendar programmable solid state time switches. They are used for switching electric circuits according to a pre-set time and date program. The AP21's AUTO PROMPTING alpha-numeric display makes programming fast and simple. Program transfer can be accomplished by using a Laptop Computer or an AP21T. The AP21TR is only 2” x 2 1/2” x 4” making it the smallest time switch ever designed specifically for traffic applications. The AP21 and AP21T draw their power from any 120VAC or 12VDC supply. The AP21TR is 120VAC powered and the AP21TRDC is 12VDC powered.
AP41
Time Switch

The AP41 is a four circuit, calendar programmable solid state time switch. It is used for switching electric circuits according to a pre-set time and date program. It has the ability to run up to ten (10) different day/week plans to accommodate different school calendars and/or traffic patterns throughout the year. The AP41 AUTO PROMPTING alpha-numeric display makes programming fast and simple.

CPR2102
Pager Programmable Time Switch

Pager programmable time switch system.
Model CPR2102 Time Switch (download programming over an alphanumeric paging network, directly from a computer COM port, upload and download from a DT2100 Handheld Display or a Palm Pilot) Activates School Flashers.
Fire Station Warning System Solar Powered

The RTC Solar Powered Fire Station Warning System provides an increased level of safety for traffic approaching a fire station when emergency equipment is departing or returning. Pressing a push button, whether in the vehicle or in the fire station causes the remote warning lights (up to 1500' away) to flash. This radio controlled system alerts passing motorists to slow down and/or stop for the fire apparatus.
Model TR-3, GPS Time Reference

RTC GPS receiver assembly mounts to top of traffic signal cabinet and plugs into the D89 connector on the TR-3.
RTC GPS receiver locks onto 3 satellites for ultra-accurate time reference.
TR-3 provides a contact closure or optional RS-232 output to set the exact time-of-day in 170, 2070 or NEMA controllers.
Programming set on circuit board, no external programmers required.
16-character, alphanumeric Liquid Crystal Display (LCD) displays Acquiring Satellites, the Day-of-Week and Time-of-Day when locked.
