Tempest 2400 Wireless Intercom System

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 SA (Stage Announce) Relay and the

five GPO relays, one for each beltstation, are available through the DB-15 Relay Connector on the back

of the Tempest base station. These relays can be triggered from the wireless beltstations.

The Stage Announce Relay function in the Tempest base station is activated by the STAGE button. The

SA Relay remains closed as long as the Stage button is pressed.

The user can reassign the following beltstation buttons and features to control an individual relay uniquely

assigned to that beltstation: Talk A/B, Talk C/D, Ch A/B, Ch C/D, Stage, Enter, or Battery < 10%. The

relay is made when the assigned button is pressed and remains closed for as long as the button is

pressed.

The individual GPO relay can also be triggered by the low battery level alert of the beltstation. In this case

the relay is made when the battery level of the beltstation reaches 10% and remains closed until the

battery is replaced or the beltstation is turned off.

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 application, cables for your RELAY connections will require some

bench work.
