A
Dual 24V PSU Inputs
The BVRD2M requires two seperate 24V DC supplies.
A fault will be announced if either of the supplies is not
connected.
B
Aux 24V Output
Auxillary 24V supply derived from both PSU inputs.
Max output 1A.
C
Open Collector
Control Outputs
6 x NPN collector outputs (max 40V @ 100mA) for busy
etc
D
Reset DSP Button
Initiates a Processor / Firmware restart
E
Analogue Inputs 1-4 Pull
Down Switch
Analogue inputs 1-4 are usually pulled high (18V).
When used for ANS, the inputs must be pulled low.
F
Analogue Voltage
Sensing Control Inputs
6 x analogue voltage sensing inputs for monitored input
access, ambient noise sensors, remote volume controls, etc.
G
Simple Contact Closure
Control Inputs
3 x contact closure inputs for unmonitored input access etc.
H
CAN BUS Connections 2 x CAN BUS ports to enable additional Modules to be
connected. Refer to section 1.7 for details of these modules.
I
RS485 Port
Connections
2 x RS485 half duplex ports for communicating to control
microphones, fire detection systems, fault reporting etc.
J
Common Fault Output
Relay Contacts
1 x volt free relay changeover contact for Common Fault
K
Optocoupled Control
Inputs from Fire
Detection System
2 x opto coupled sounder circuit inputs:
EM input "All Evacuate" has processor bypass option,
I/P1 is programmable
L
Audio Inputs 1 & 2
Electronically balanced line -20dB audio inputs.
Normally reserved for Fire Microphones as both inputs
have processor bypass option.
M
Bypass Surv Level
Must be set to match BVRD Mic (3V3 if not selectable)
N
Audio Inputs 3 - 8
Electronically balanced line -20dB audio inputs.
O Audio Outputs 1 - 7
Electronically balanced line 0dB audio outputs
P
Monitor Output
Not normally used
Q Auxillary Front Panel
Feature not implemented.
R
BVRDNET Expansion
BVRDNET Terminations (when fitted)
S
USB Port
Parallel port with the front USB Connector
