Using Vo-Comm (if fitted)
Once Vo-Comm has been programmed (see previous pages)
the Vo-Comm will operate in one of two ways.
1) Alarms Only - The Vo-Comm will only communicate when an alarm occurs on
a Closed (Set) system. This mode is active when the Open / Close option
is Off.
2) Alarms & Status - The Vo-Comm will communicate when an alarm occurs or
when the system is Closed or Opened (Set or Unset).
Receiving a Call From Vo-Comm
When Vo-Comm calls you it will start to pass its message as soon as you pick up the
telephone.
At the end of the message you will hear a single tone, at this point press a numeric
key on your telephone keypad
twice
. A rising tone will be heard that indicates that the
call has been acknowledged.
If you do not acknowledge the call or hear the rising tone the Vo-Comm
will repeat the message several times and then go on to dial the
remaining telephone numbers until the call is acknowledged.
Messages From Vo-Comm
Two types of message will be sent by Vo-Comm. Either a status message or an alarm
message.
Typical Status Message
‘
Site 05 Close User 01
’
This would indicate Site ID 05 was Closed by User 1
The term Closed = Set
The term Open = Unset
Note:
In order for the Vo-Comm to report Openings and Closings, the Open
Reporting for that user must be programmed to On within the Programming
User Codes section.
Typical Alarm Message
‘
Site 05 Alarm Zone 06
’
This would indicate an alarm at Site ID 5 has occurred on Zone 6.
