3.2 Alarm Connections
Use normal hookup wire (approximately 20 gauge) to connect alarm sensor
equipment to the Remote Video Unit. Remote Video Unit alarm inputs are
usually configured as normally open (NO). If required, they can be factory
configured as normally closed (NC) or End Of Line (EOL). Refer to
Appendix D: Configuring Alarm Inputs.
Most alarm sensor units have a dry contact for outputs, usually providing
type form 'C' outputs (both Normal Open and Normal Closed contacts). Note
which type you have and select the Normally Open or Normally Closed
option. Figure 4 shows the NO, NC, and EOL (End of Line) alarm
configurations.
Normally Open
Alarm is active when switch goes ON.
Normally Closed
Alarm is active when switch goes OFF.
End of Line (EOL)
Alarm is active when switch goes ON, or
when wires to the resistor are opened.
This provides circuit integrity confidence.
