GPO Relay Contacts

Tempest Wireless provides six General Purpose Output (GPO) contact closures. These GPO contact closures can be used

for interfacing with other external devices. The Stage Announce (SA) Relay and the ve GPO Relays, one for each BeltSta-

on, are available through the DB-15 Relay Connector on the back of the Tempest BaseStaon. These relays can be trig-

gered from the wireless BeltStaons.

The SA Relay funcon in the Tempest BaseStaon is acvated by the STAGE buon. The SA Relay remains closed as long

as the STAGE buon is pressed.

The user can reassign the following BeltStaon buons and features to control an individual relay uniquely assigned to

that BeltStaon:

» Talk A

» Talk B

» Ch A

» Ch B

» Stage

» Enter

The relay is made when the assigned buon is pressed and remains closed for as long as the buon is pressed.

The individual GPO relay can also be triggered by the low baery level alert of the BeltStaon. In this case the relay is

made when the baery level of the BeltStaon reaches 10% and remains closed unl the baery is replaced or the Belt-

Staon is turned o.

All relay contacts can support 1 Amp at 30 VDC.

The relay completes a circuit. Tempest does not supply any power to the circuit.

Since every user will require a custom applicaon, cables for your RELAY connecons will require some bench work.
