APPARATUS CONTROLLER TS90685

Tilavahti® Tilavahti® enables local control of emergency lights within a central power system. It monitors the electrical network on a group panel basis and controls local emergency lights. Local control ensures that emergency lights switch on if there are disturbances in the power supply to the normal lighting of the group panel. Both continuously operating and intermittently operating emergency lights can be connected to the same group cable. How it works Tilavahti® is installed in the emergency light group cable before the emergency lights. Voltage information is supplied to Tilavahti® from the area’s group panel, and it monitors the phase status of the group panel. When there are phase deficiencies, this information is transmitted via Tilavahti® to the intermittently operating emergency lights, causing them to switch on. When the normal power supply is restored, the emergency lights remain on for approximately 20 seconds, after which they automatically turn off (if the delay setting is 0 minutes). Real-time power outage notifications The TST6804 and TST6805 devices also feature a switch control input, trimmer, or DIP switch. These allow setting how long the lights remain on after the normal power supply is restored (0–15 minutes). The device’s relay output can also be used to provide an alarm for a local power outage. In the Tilavahti® system, intermittently operating emergency lights must be addressable (the type code ends with the letter K).
