The Emergency Lighting Test Switch, ELTS, is intended for testing single phase circuits for emergency lighting according to AS/NZS 2293.1:2018. The ELTS is normally closed, allowing the full supply to emergency lighting circuits up to 20 A per circuit in absence of test.
On a periodical basis, in accordance to the norm, the ELTS enables the operator, through a key lock or a code lock, to operate the ELTS and cut off the power for a duration either preset (60, 90 or 120mins) or programmable through the front panel buttons.
An OLED display allow count down as well as advance sequential programming. Statistics of operation are also available within the unit.
The ELTS allows the command of an external contactor through a dry output contact up to 5 A 30 VDC or 220 VAC.
For optimal safety the ELTS is power supplied by an external power supply, single phase 230 VAC.
