ALARM MENU
Figure 16. Alarm Menu
Use the Alarm menu to set up alarms and relays for cameras.
• Alarm Input Setup: Use this option to connect or disconnect alarms for any camera at any time. If you connect an alarm, you must
associate it with a camera and select the alarm type - normally closed (N/C) or normally open (N/O).
• Relay Output Setup: Use this option to set up a relay in response to alarms. For each alarm, you can enable or disable the relay, select
whether the relay mode is latched or transparent, and set the delay time.
A latched relay continues operating for the duration set for it even if an alarm is received but the alarm sensor stops working. A transparent
relay stops working if the alarm sensor stops working after it receives an alarm.
Duration refers to either the delay between the occurrence of an alarm and the time at which a relay starts or the length of time that the
relay remains in effect after the alarm occurs. Duration times can be increased by 5- or 10-second increments for the first minute, and then
by one- or two-minute increments for a maximum of five minutes. Duration may also be set to continue until an operator responds and turns
off the alarm with a key (Until Key-In).
• Relay Type: Use this option to indicate whether a relay is normally open (N/O) or normally closed (N/C).
