Overview
The ALC-PRM-VFC photocell will turn lighting on when the
ambient light falls below a preset level. The lighting will
then be turned off when the total light level rises above a
separate preset level. The unit also has a switch input for
manual override.
An integral, adjustable time delay prevents nuisance
switching caused by, for example, dark clouds.
The unit has a voltage free changeover output which can
be used to switch, a BMS or lighting control system as well
as switching a load directly.
All functionality is fully programmable using an IR handset.
