RELAYS SETUP
The DVR5100 supports up to four relay devices. Use them to trigger external devices. The unit supports both momentary and continuous relay
operation, either normally open or normally closed (refer to Figure 61).
You can operate the relay interactively, during an active connection, or automatically to coincide with certain events. Relays work like switches.
When triggered, relays can activate an external device such as a siren, light fixture, or door lock. Refer to Table AA on page 75 for more
information on relay settings and defaults.

MODIFYING RELAY SETTINGS
1. Use the keyboard and mouse [or the on-screen keyboard] to modify the relay name. Enter a user-friendly name for the relay device. This
makes it easier to recognize individual devices on your network.
2. Select the desired relay mode. The options are Off, On (default), Toggle, and Pulse.
3. If you are using the pulse mode, modify the following settings:
• Select a pulse value for the relay period. This setting defines the total time in tenths of a second (5 to 1,000) for the relay control pulse
(1 second is the default value).
• Set the percentage of time during the defined period that the relay will be in the ON state. The default value is 50%.
• Set the number of times (0–99) the relay will be pulsed (that is, placed in the ON state) during the defined period. The default value is 5.
