Power Fail (Not Programmable)
This channel’s input is reported as either Open or Closed. It is a normally Closed channel. It
monitors the DC voltage input that it is receiving. When it drops too low, the dialer will resort to
using the dialer battery if one is installed.
Alarm Configuration (Inputs Only)
Each input channel can be setup to handle channel values in a specific way. Each channel can be
setup as either a Status, Call On Alarm, or Call On Alarm and Return channel.
A Status channel indicates that this channel will not make any alarm call outs. It will recognize
that a fault condition has occurred, but no alarm condition will be reported for this channel.
A Call On Alarm channel will cause alarm call outs when an alarm conditions occurs. If the
alarm condition clears without being acknowledged, the dialer channel will now indicate that its
status is ‘Now Normal.’
When a channel setup as Call On Alarm goes into alarm and gets acknowledged, i.e. someone
learned of the alarm and commanded the dialer to stop making alarm call outs, the channel status
will be ‘Acknowledged.’ Once acknowledged, this channel will go into a snooze period where it
will not call out for this alarm condition (See section Editing the System Setup, Page 72 for
how to program the Snooze Period). When this snooze period expires, alarm call outs will
recommence.

A Call On Alarm And Return (Call/Return) channel has the same properties of the above Call
On Alarm in addition that a new set of call outs will be generated when the alarm condition
clears. Basically, call outs are started whenever the channel alarm condition changes.
