Mounting Considerations
Depending on local regulations, the bases can be
surface mounted using anchors, mollies, or wing nuts.
The bases can be directly mounted on single‑gang
switch boxes or mounted on four‑inch octagonal
electrical boxes using the supplied adaptor plate.
Notice
Ensure the volume of any electrical box used
accommodates the number and size of conductors
as specified by the National Electrical Code (NEC)
or any local regulations having jurisdiction.
EOL Supervision
Use one D293E Base for the last detector on the loop
or one D275 module per detector loop. Use the EOL
resistor(s) specified by the control panel
manufacturer.
