How does night light circuitry (constant illumination) affect S60FSD and S44CSD testing?
The S60FSD and the S44CSD will postpone a scheduled test for up to 72 hours if it finds that the AC ballast is illuminated (the lights are on). In the case of emergency lighting on night light circuitry, the AC ballast is constantly illuminated. Therefore, the S60FSD and the S44CSD will execute testing after the delay maximum has expired.
