The facory
installedTD Option provides an automatic time delay after AC Power is restored to an
emergency light unit. A user-adjustable setting of 1 - 60 minutes determines the period of
operation before automatic reset to standby condition. Such application is useful when
testing remote heads, or in H.I.D. areas where illumination is lost until AC lamps
re-strike and return to full brilliance. The "TD" feature is included with the
Quik-Chek Option. |
