2.3.8 B50 4-20mA Combination Board

A Combination alarm can contain a B50 board that
contains four 4-20mA inputs that can be used with
a two or three-wire transmitter. The board also six
normally closed dry contact relay outputs. Each alarm
panel can have a maximum of one B50 board.
Identify each set of field installed 4-20mA input signal
wires (2 or 3 wires per set) inside the alarm backbox.
Route each set of input wires to the appropriate ter-
minals on the B50 board. Connect each set of signal
wires to the terminal blocks, noting the correct polarity
(Figure 2.9).
Figure 2.9: B50 Board Wire Routing
CAUTION:
Source equipment signal wires must be connected
to normally-closed, dry contacts. No electrical volt-
age can be present and contacts must be closed
during normal equipment operation. When con-
tacts open, an alarm condition will be activated.

2.3.9 Alarm Panel "Mirroring"

Each alarm panel has an Ethernet port on the back of
the front panel assembly. By connecting the alarm to
the hospital network, via Ethernet, or directly cabling it
to another alarm panel, signals and gas pressures can
be pulled from one panel and displayed on another
panel.
A category 5 CROSS OVER cable is required for con-
necting alarm panels directly to each other. Otherwise,
standard cabling can be used with a facility's Ethernet
hub or switch to connect panels.

2.3.10 General Fault Relay

The B60 Gas Input board is supplied with an alarm
panel general fault output relay.
This relay has a set of dry contacts that is wired
normally closed.
The relay will activate when ANY alarm on the ENTIRE
alarm panel is activated. Relay will remain activated as
long as alarm condition is active, even if audible alarm
is silenced by MUTE button.
When alarm condition is corrected, relay will
deactivate. Relay contact ratings are 5A @ 30VDC / 3A
@ 250VAC. Refer to HTM Area Wiring Diagram (Section
3.2).

2.3.11 Ethernet

Alarms can be connected to a facility's network via
Ethernet by plugging the network cable to the port
provided on the back of the alarm front panel.
