AVR-8 Installation and Operation Manual
INSTALLATION
INSTALLATION
If DIP switch number 5 is turned on, a beep will be added after each of the above
relay commands, except in the case of the trailing edge relay, in which case, the beep
will be placed between the DTMF tone and the pulsed relay.
If DIP switch number 6 is turned on, the 1-minute timer will hang up the line if no
touch-tone issued within the 1 minute. This would be used if no CPC or the AVR-
8 were used behind a PBX. Note: 99* will hang up the AVR-8 with this switch OFF
or ON.
TOWER LIGHT MONITORING
DIP Switches 7 and 8 are used to set a time-out value for tower light monitoring. If
7 & 8 are off, then this function is disabled and the inputs can be used the same as
the others. If either 7 or 8 are on, then these inputs are dedicated to the tower light
monitoring function. Input 7 is used to input day/night information from a photo
detector, and input 8 is used to input whether the tower lights are on or off. When a
photo detector senses a night condition, the output contacts should be connected
between ground and input 7 so that it is brought low when in a night condition. This
starts a timer that is set by using the settings of DIP switches 7 & 8 as follows:
7
8
0
0
OFF
0
1
10 minutes
1
0
20 minutes
1
1
30 minutes
When a closure is sensed on input 7, the timer will begin counting. After the
assigned time out period has expired, the AVR-8 will look at input 8. If input 8 is
closed, then the tower lights are considered to be on, and everything is normal. In
this case, the AVR-8 will call the call-out list for input 7 and play the message asso-
ciated with input 7. This should be something like: “Tower lights operating nor-
mally”. If input 8 is not closed, then an alarm will be called out using input 8's call-
out list and message. Something like: “Tower lights are off” should be recorded for
input 8.
