RETROFIT LOW VOLTAGE SWITCH WIRING CONVERSION
Existing low voltage switches may be converted for operation with the LMCP retrofit panel. Retrofit panel input terminals are limited to
toggle operation only. Any existing ON or OFF buttons wired to LMCP terminals will operate as toggle buttons. If this is unacceptable,
use the LMIN-104 DLM Low Voltage Input Module for wiring conversions, which supports many input operations including ON-only and
OFF-only. See LMIN-104 product documentation for more details.
NOTE: Prior to converting for operation with the DLM system, any existing switch wiring must be verified to not run with line voltage
wiring. Line voltage wiring can magnetically couple voltage onto low voltage wiring and will cause improper operation.
NOTE: Wiring shown is applicable to ON/OFF retrofit panels only. 0-10V retrofit options are not available, nor is wiring shown
compatible with 0-10V LMCP panel relay cards.
