About this detail

A single-pole zero-to-two-hour spring-wound room wall timer switch is installed in a single-gang box or ganged with other devices, paired with an engraved coverplate reading "EMERG. LIGHT OFF". Power is supplied from a normal power lighting panel via a 20A single-pole circuit with neutral conductor running to the switch and downstream devices. The circuit feeds an emergency/night light luminaire equipped with an AC ballast and an IOTA I320 series 1400-lumen emergency ballast with Redi-Test and fail-alarm options.
