Verbatim Autodialer Specifications
I-4 Verbatim Owner's Manual
I.7 Input Monitoring Function
The unit shall continuously monitor the presence of AC power and the status of
four contact closure inputs. Unit shall optionally be field upgradeable to incor-
porate a total of 8, 16, 24, or 32 dry contact inputs. AC power failure, or
violation of the alarm criteria at any input, shall cause the unit to go into alarm
status and begin dial-outs. Unit shall, upon a single program entry, automati-
cally accept all input states as the normal non-alarm state, eliminating possible
confusion about Normally Open versus Normally Closed inputs. Further, as a
diagnostic aid, unit shall have the capability of directly announcing the state of
any given input as currently “Open Circuit” or “Closed Circuit,” without
disturbing any message programming. Each input channel shall also be indepen-
dently programmable, without need to manipulate circuit board switches or
jumpers, as Normally Open or Normally Closed, or for No Alarm (Status Only),
or for Pulse Totalizing, or for Run Time Metering.
I.8 Run Time Meter Inputs
Any dry contact input can be programmed to accumulate and report the number
of hours their respective input circuits have been closed. Any such channels will
never cause an alarm, but on inquiry will recite the channel’s message accord-
ing to the status of the input and then report the closed circuit time to the tenth
of an hour. The input will accumulate and report in tenths of hours up to a total
accumulated running time of 99,999.9 hours. The initial value of the Run Time
Meter shall be programmable in order to agree with existing electromechanical
Run Time Meters. Up to a total of 8 Run Time Meters may be programmed.
I.9 Pulse Totalizer Inputs
Any dry contact input can be programmed to accumulate the number of pulses
(momentary contact closures) occurring at the input. The maximum input pulse
rate must not exceed 100 pulses per second, and if the rate is over 50 pulses per
second, the pulses must have a 50% duty cycle. The user shall be able to
program an initial starting value and a scale factor for each pulse totalizer input.
The pulse totalizer input shall cause an alarm call upon reaching a user defined
alarm setpoint.
I.10 Alarm Message
Upon initiating an alarm phone call, the system is to “speak” only those chan-
nels that are currently in “alarm status”.
