PTT1 (In Field)


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


The PTT1 Performance Test Tag is used in safety critical situations where the continued operation of the reader has to be monitored. It ensures that the reader remains fully operational, and gives an assurance that the desired reading range is being maintained. The CRx reader can address several aerials, each of which must have a PTT1 to monitor the field.

The reader checks that each test tag aerial combination is functioning correctly. If either the test tag or the reader is compromised a relay will operate and the reader can generate an alarm report via the Wiegand or RS232 output port. The PTT1 test tag can be used with CRx  type readers such as CR1-DS-MS which have multiple aerial loops.

The PTT1 is required when a split transmitter and receiver solutions has been employed.

An alternative product is the PTT2 which is an "in line" performance test tag.
