Sash light curtain
The Sash Light Curtain is a safety device designed to detect whether the opening below
the sash is clear of obstructions before the sash is automatically closed.
•
When an obstruction is detected, the sash drive is disabled and the alarm is activated.
•
The Sash Light Curtain comprises an infra-red transmitter mounted on one side of the
fume hood and an infra-red receiver mounted on the opposite side of the fume
hood's inner chamber.
•
The infra-red transmitter has multiple, closely spaced, Light Emitting Diodes (LEDs) to
facilitate the detection of small objects.
