Bypassing Controls with the IOTA ETS 20
IOTA® ETS 20 and ETS 20 DR solutions allow the use of local controls on designated emergency lighting circuits, enabling users to turn multiple fixtures on or off or dim to desired levels without impacting their code-required emergency lighting function. During an emergency, the IOTA ETS 20 can bypass local controls or dim settings and cause the designated emergency fixtures to be powered at full light output for optimal occupant safety.
Activation By a Fire Panel or Other Trigger Device
Typically, an ETS 20 will activate when it senses a loss of normal power, however a second device, such as a fire panel or other dry relay contact can signal the ETS 20 to activate even if normal power is still present. ETS 20 devices include a blue jumper wire that senses position of an alternate dry contact. If a fire panel signal is detected, the connected ETS 20 device will engage and override the controls on the circuit, forcing the load to operate at full output regardless of local switch positions or dim settings.
