WVRC-4 Installation and Operation Manual
PROGRAMMING
When item (3) is selected from the PGM Menu, the Access Code, Lap, Ring Count, Repeat
Count, Silence Sensor Delay Time, Power Fail Time, Hang up time, Monitor access code
and Analog Debounce Time can be programmed.
The “Access Code” may be changed from the default code of 123, allowing a user all con-
trol functions.
“Lap” defines the number of times the WVRC-4 will go through all of the numbers in the call-
out list when calling out an alarm if it does not receive an acknowledgement.
NOTE: Alarms are acknowledged by pushing the star (*) key when an alarm is called
out.
“Ring” defines the number of rings required before the WVRC-4 answers a call.
“Repeat” is the number of times the voice message will be repeated when the alarm is
called out. Since there is no way of knowing when the remote party answers the phone line,
the WVRC-4 will start playing the alarm message a few seconds after dialing for the
“Repeat” number of times. So when an alarm call is answered, you may pick up the phone
in the middle of an announcement or there may be a few seconds of silence before the start
of the next message. Once the star (*) is entered to acknowledge the alarm, it will stop play-
ing the message. You can now enter your access code and perform control functions or
polling.
“Silence” Time is programmed with a value of 0-9 with a 0 being OFF and 1-9 with val-
ues are as follows: 1 = 10 sec, 2 = 30 sec, 3 = 60 sec, 4 = 1.5 min, 5 = 2.0 min, 6 = 2.5 min,
7 = 3 min, 8 = 4.0 min and 9 = 5.0 min. Note: The silence sensor audio must be restored
for a minimum of 10 seconds and the alarm must be acknowledged before it is cleared.
“Power Fail” Time is programmed in 10 second values. For example, 2 = 20 seconds of
silence or power failure to generate an alarm, 9 = 90 seconds. If it is set to “0”, the alarm
will be turned off and will not call out.
The “HU” value refers to the number of minutes the WVRC-4 will remain off-hook after
answering the call before hanging up automatically. Normally a CPC signal is sent from the
Central Office to signal it to hang up. If you are connected to a standard phone line, you
can set the HU to 0, and it will remain off-hook until the CPC signal is received. If it is con-
nected on the other side of a PBX system that does not pass the CPC signal, then a value of
1-9 minutes should be set into HU to keep it from remaining off hook and causing the line
to be busy. The HU timer will be reset each time a valid DTMF is decoded showing activi-
ty. Once there is no more activity, the WVRC-4 will time-out after the HU time value and
force a hang-up.
The “Monitor Access Code” is an alternate access code that allows a user only to
monitor or poll the various inputs. No control functions can be performed unless a valid
Control Access code has been entered.
The “Analog (metering) Debounce Timer” is the number of ten second increments required
for the analog inputs to accept an alarm condition. For example, if it is set to 3, an Analog
input must be in an alarm condition for 30 seconds before an alarm will be generated.
NOTE: If set to “0”, analog alarms will be disabled and will not call out during an
alarm.
