Technical Notes
Inputs to a Multi-Media DVR Used by Hardware Devices
Honeywell recommends that installers report the connection of input devices to the
organization Multi-Media System Administrator (Multi SA), indicating if the devices are
using connections that are: normally open, normally closed or end-of-line.
Alarm Sensors
Most alarm sensor units have a dry contact for outputs, usually providing normally open
(NO) contacts or normally closed (NC) contacts. The sensor inputs to a Multi-Media video
DVR are configured for normally open (NO) devices.
End-of-Line
A sensor input can also be configured as EOL (end-of-line or protected). The load for an
EOL connection is 2 k*, nominal.
