What do the relays do when my ERP, ERP-FT, or SensorIQ loses power?

Question

If my Echo Relay Panel (ERP), Echo Relay Panel Feedthrough (ERP-FT), or SensorIQ panel loses power, what do the relays do?

Answer

In all three cases the relays are mechanically held in whatever position they existed when the rack loses power. If the relays need to be turned on or off while the rack still has no power you can manually flip the relay state by following the instructions for each rack below:

  • ERP - Flip the small black switch on the relay.
  • ERP-FT - Flip the yellow switch on the relay. You may need a flat blade screw driver to help.
  • SensorIQ - Turn the breaker off, and back on.
