Power Supply - BeaconMedaes TotalAlert Infinity Installation, Operation And Maintenance Instructions

TotalAlert Infinity™ HTM Medical Gas Notification System
The following rules along with references to this
manual's schematics clarify wiring requirements.
• Digital Gas Sensor Modules
Two conductor cables (must be twisted pair type with
shield) are required for each Gas Sensor module to the
Gas Input board (B60).
Refer to HTM Area Wiring Diagram (Section 3.2).
• BeaconMedaes Line Contact Monitoring
The Total Alert Infinity uses BeaconMedaes Line
Contact Monitoring on all input signals. This type of
connection is relatively immune to interference, but
shielded cables are still recommended. Five conduc-
tor cables (must be twisted pair) are required for each
channel.
BeaconMedaes recommends the following cable type,
and a maximum length of 100 meters.
Refer to HTM Central / Combination Wiring Diagrams
(Section 3.1 / 3.3) for B30, B50 signal boards.
• Relay outputs
Two conductors are required for each signal between
relay output terminals and remote device (such as
a building automation system). Refer to the wiring
requirements of the connecting device when select-
ing the appropriate type of conductors to use (i.e. wire
gauge, twisted or not, shielded or not.)
Refer to HTM Central / Combination Wiring Diagrams
(Section 3.1 / 3.3) for B4X signal board.
• Digital display module "mirroring"
Two panels may be connected together so digital
display module pressure reading(s) of first panel will be
duplicated at second panel.
An eight conductor category 5 CROSS OVER cable is
required for connecting alarm panels directly to each
other. Otherwise, standard cabling can be used with a
facility's Ethernet hub or switch to set up a connection
between panels.
• Source signal "mirroring"
Two panels may be connected together so source
signals of the first panel will be duplicated at second
panel.
An eight conductor category 5 CROSS OVER cable is
required for connecting alarm panels directly to each
other. Otherwise, standard cabling can be used with a
facility's Ethernet hub or switch to set up a connection
between panels.
• Ethernet
For each alarm panel to be networked, an eight
conductor category 5 network cable is required
between each alarm panel and a facility's Ethernet hub
or switch.

2.3.4 Power Supply

NOTE:
All wiring shall be protected from physical damage
by raceways or conduit in accordance with local
electrical code.
A power supply assembly is provided with the alarm
panel. The installer must use 18AWG copper supply
wiring minimum with an insulation of not less than
0.8mm (1/32in) thick. Power supply shall be connected
to a building installed circuit breaker. Circuit breaker
shall be a maximum of 15 amps and marked as
disconnecting means for the alarm panel. It is
recommended that the circuit breaker be in close
proximity to the alarm panel and properly selected
according to local regulations.
A knock-out is provided in the lower right hand corner
of the backbox for main power (Figure 2.4). Wiring is to
be installed in accordance with local standards.
No other holes should be punched or used.
Several additional holes or knockouts are provided on
the top panel and bottom for entrance of low voltage
field wiring (Figure 2.4).
Several additional knock-outs are provided on the top
and bottom of the backbox for entrance of low voltage
