950 Installation Manual | Crawford Cdm9

This was where it got spooky. The wiring diagram looked like a city map designed by M.C. Escher. “Connect the red wire to the blue wire only after the green wire has pulsed twice,” the instructions read. Elias squinted. He stripped the wires. He connected them. A soft hum emanated from the unit. “Status Light should be Amber,” the manual said. It was Amber. “If Status Light is Pulsing Red, disconnect immediately and vacate the premises.” Elias exhaled. Amber was good. Amber was safe.

The CDM9 system usually pairs with a 950-series control box. Power Supply: crawford cdm9 950 installation manual
