Relay K2
- is controlled by the Magnetic Bond Switch S3. The output contacts of K2 are
connected to the red/green, red/yellow and red/black wires in the interconnecting cable. These
outputs are intended for use with an external device such as an automatic door opener.
Electromagnet
– The electromagnet operates on a nominal 24Vdc and draws approximately 300
mA when energized. Diode D8 is across the magnet terminals to suppress voltage spikes that can
be generated when the magnet de-energizes.
