Troubleshooting Tips
Verbatim Owner's Manual 9-3
Unacknowledged alarm status is indicated by the corresponding channel
number flashing. Acknowledged alarm status is indicated by the same light
remaining on continuously without flashing.
If you don’t observe this, press PROGRAM and then press 7 0 1 ENTER to
check your first phone number. Press 9 0 2 to check the Global (overall) Alarm
Trip Delay. For the specific channel ZZ (2 digits) that you are attempting to
create an alarm on, also press 6 ZZ to check for any longer Individual Alarm
Trip Delay setting.
Check the Normally Open/Normally Closed alarm criteria programming for this
channel by pressing 5 ZZ. Make sure it is not set for No Alarm or for Run Time
Meter, since these settings would not allow an alarm. Now, for example, if the
channel is configured Normally Open, you will want to temporarily provide a
Closed Circuit at its input to trip the alarm. You can directly read and verify the
Open/Closed status you are applying by pressing 0 ZZ 0. You may also use a
DC voltmeter to trace your circuit connections. With the Verbatim autodialer
turned on, an Open Circuit to a channel contact input reads 5 volts DC with
respect to the “C” terminals or electrical ground. A Closed Circuit reads zero
volts.
Unit keeps calling when it should not.
Be sure that the initial alarm call is in fact being acknowledged. The unit will
specifically state “alarm is acknowledged” at the moment you successfully
acknowledge the call. The unit will accept a tone acknowledge only following
the prompting warble beep.
Also, be sure that the alarm violation has been corrected. Otherwise, even if the
alarm is acknowledged, when the Alarm Reset period times out, dialing will
begin again.
Write down exactly what the unit recites when it gives the unwanted call. This
provides valuable guidance as to the cause and correction of the problem. You
may need to lengthen the Alarm Trip Delay in order to minimize nuisance
alarms, particularly the power failure Alarm Trip Delay (code 920). If you hear
an alarm message with the phrase “now normal” added at the end, it means that
the violation occurred long enough to trip the alarm but has returned to normal
by the time you are hearing the report. In the case of power failure, if the power
has been restored by the time the message is being heard, the message will be
“Power is on”. The fact that power is mentioned at all lets you know that there
has been a power failure lasting longer than the power failure Alarm Trip
Delay. Power will continue to be mentioned in any phone call or front panel
status check, until the Alarm Reset time expires.
