Ptt2 00


The PTT2

Once adjusted the unit provides continual feedback on the status of the reader antenna being monitored. Any reduction in reading range, or probability of detection, is flagged by the internal relay changing state and the LED indicators on the front of the unit.

The unit is designed to operate with all Census loop aerial units. The CRx reader can address several aerials, each of which must have a PTT2 to monitor each detection field.


  • Monitors Reader Detection Zone Integrity
  • Scrambled RF Communication
  • Monitors Reading Range
  • Relay Contact to Indicate Fault Conditions
  • Maintenance-free


Access Control

Automatic staff registration for safety roll call or attendance registration through real-time alerts and accurate location information.

Car Parking

Create an intelligent parking system where the entry and exit of cars are monitored, with vehicle or driver identification, or both.

Technical Specification

The reader firmware checks that each test tag/aerial combination is functioning correctly. If either the test tag or the reader is compromised, an alarm relay will operate. The reader can also generate an alarm report via the Wiegand or RS232 output port. The PTT2 test tag can be used with all CRx type readers such as the CR1-DS-MS which have multiple aerial loops. The PTT2 cannot be used with the CR1-DS1 split transmitter and receiver version. This unit must be monitored using PTT1 units.
