Alarm Input Operation
Basic Operation
The Eyz-On has a single alarm input connection. To use the alarm input feature
on the Eyz-On system the user will need to connect a N.O. (normally open)
switch or relay to the alarm input connections.
When the
Eyz-On detects closure across these terminals an alarm connection
will be recorded by the Eyz-On system.
In no case should you apply any voltage or current to either the
alarm "+" input or the alarm "-" input terminal.
Alarm Detection
The Eyz-On system monitors the alarm input terminals for a contact closure.
The alarm input must have a contact closure for a minimum of 1 second for the
Eyz-On to recognize an alarm input. Alarm contact closures of less than 1
second may or may not be detected. ( The 1 second limitation is not user
configurable.) There is no maximum time that an alarm input contact closure
can be held close, but only one alarm input event will be recorded for each
contact closure.
Alarm Operation
For proper operation the user must set-up the "Settings->Event Inputs->Alarm
Input" page. This page will determine what actions the
Eyz-On takes when an
alarm input is detected.
Alarm Limitations
The Eyz-On does not monitor the alarm input terminals when either it is trying to
acquire an Ethernet IP address or while the USB cable is inserted. Therefore,
care should be taken if the
Eyz-On is set-up in DHCP mode since the Eyz-On
will not monitor the alarm input terminal until either an IP address is acquired
from the DHCP or the
Eyz-On has timed-out on the DHCP request; this may be
as long as two minutes.
If the
Eyz-On is set-up for a static IP address this limitation does not apply.
