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 fi ve other GPO Relays, enough for each
BeltStati on to control one, are available through the DA-15 Relay Connector on the back of the Tempest BaseStati on. These
relays can only be triggered from the wireless BeltStati ons.
The SA Relay functi on in the Tempest BaseStati on is acti vated by the STAGE butt on on the BeltStati on. The SA Relay remains
closed as long as the STAGE butt on is pressed.
The user can reassign the following BeltStati on butt ons and features to control an individual relay uniquely assigned to that
BeltStati on:
» Talk A
» Talk B
» Ch A
» Ch B
» Stage
» Enter
» Call
» Low Batt 10%
The relay is made when the assigned butt on is pressed and remains closed for as long as the butt on is pressed. The
individual GPO relay can also be triggered by the low batt ery level alert of the BeltStati on. In this case, the relay is made
when the batt ery level of the BeltStati on reaches 10% and remains closed unti l the batt ery is replaced or the BeltStati on 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 applicati on, cables for your RELAY connecti ons will require some bench work.

Acti ve Channel Relay
This mode of relay operati on can control how all BeltStati ons on a parti cular BaseStati on functi on with respect to relays.
When acti ve, any TALK butt on pressed for a respecti ve channel will close the corresponding relay on the BaseStati on. For
example, if any TALK butt on on “Ch A” is pressed then “Relay 1” will close. If TALK is pressed on “CH B” then “Relay 2” is
closed, “CH C” for “Relay 3” and “CH D for Relay 4.”
BaseStati on “Relay 5” may be assigned to any of the existi ng relay triggers from any or all BeltStati ons, and the Stage Relay
operates normally. It is not possible to exclude any BeltStati on(s) from this mode of relay operati on once the BaseStati on
has been set into this mode.
