Any of the 54 access control inputs available on the 3 BVRCI termination modules may
be programmed to route any of the 23 input sources to any of the 20 outputs when the
control input is closed or via a 1k2 resistor to 0V.
In the example above, if input access 10 were closed to 0V via a 1K2 resistor, fire
microphone 01 would be broadcast to outputs 01-05 and outputs 06-10 would be silent.
If F/M 01 (audio input 1) has surveillance enabled, access input 10 will be monitored
and faults will be announced if the access input is not correctly terminated
.
Note:
Fire microphone 1-4 have a time out delay of 3 minutes and therefore will only allow the
user to speak for this time.when the 3 minutes has expired the system will release the
microphone and an access fault will be announced.
Note:
If this fire microphone is to be accessed via the RS485 serial data link, an unterminated,
unused input must be assigned to output 01 to enable monitoring of the serial link.
Inputs 1-8 on the 1
st
BVRCI are used for page microphones 1-8 press to speak access
.
Inputs 1-8 (19-26) on the 2
nd
BVRCI are used for ambient noise sensors outputs 1-8 and
inputs 1-8 (37-44) on the 3
rd
BVRCI are used for ambient noise sensors outputs 9-16.
If not required any of the above inputs may be programmed to provide access to any of
the audio channels.
To change the access input, move the cursor along until it flashes beneath the required
output 1-10 window. If the access input required is between 0-9, enter it directly using
the numbered keys, or using the + or – keys step to the number required between 00
and 54.
