DESCRIPTION
The EM-24xx is a low voltage photocell used for operating exterior lighting. It is used for signaling light levels to Wattstopper lighting
control panels and devices that control exterior lighting.
• Typically the EM-24xx is mounted on the exterior or roof of a building with the light sensing window facing north.
• The EM-24xx’s 1/2” threaded male conduit base can be connected to conduit fittings or to junction boxes with the supplied locknut.
• For the EM-24A2, connect 24 VAC to the two black wires.
Normally, this power is supplied from the lighting control panel or device the photocell serves.
• For the EM-24D2, connect to 24VDC with black wire to (-)DC and the white wire to (+)DC polarity.
• The relay contact red wires are connected to the lighting control panel or to a low voltage controlled load.
Contacts are rated 1A@30VAC/VDC.
