Series Card Key Switch from WattStopper
turns electrical circuits on or off when a card key or HS-FOB Key Fob is
inserted or removed from its slot. More code compliant than a simple master
wall switch, the HS Card Key Switch ensures that lights are off when the room
is vacant. The attractive, low profile switch features a backlit card key slot
to provide visibility in darkened rooms and a 30-second egress time delay.
Plus, the HS Series Card Key Switch is available in five decorator colors and one,
two or three gang switch plate covers.
The HS-100 is a low voltage unit with a normally open and

that serves as a master switch for a single guest room circuit. Both can use
the same card key that unlocks the door and are compliant with current
requirements in both the IECC and ANSI/ASHRAE/IESNA Standard 90.1.
