Determining Number Of Conductors

The following rules along with references
to this manual's schematics clarify wiring
requirements.
• Digital display modules to sensors
Two conductors are required between
each digital display module and
sensor module (twisted pair).
Refer to Wiring Schematic 2
(Page 47).
• Switched signal inputs
Two conductors are required for each
signal between the signal input
terminals and the source signal switch.
These signals can originate at source
equipment or from pressure switches
mounted on main pressure / vacuum
pipelines.
When two master alarms are required,
the same switch / relay contacts can
be wired to both alarm panels.
(See CAUTION below).
Both pairs of wires should originate
from switch/relay contacts.
Refer to Wiring Schematic 3
(Page 48) for multiplexer/breakout
board.
Refer to Wiring Schematic 5
(Page 50) for multi-signal module.
Refer to Wiring Schematic 10
(Page 54) for pressure switches.
CAUTION:
Do not connect TotalAlert 2 master/combo alarm
to switch/relay contacts connected to any alarm
panels other than those listed below:
• TotalAlert 2
• MEGA2
• MEGA
• Relay outputs
Two conductors are required for each
signal between relay output terminals
and remote device (such as a building
automation system).
Refer to Wiring Schematic 4
(Page 49) for multiplexer/relay board.
Refer to Wiring Schematic 7
(Page 52) for multi-signal module.
Refer to Wiring Schematic 8
(Page 53) for annunciator module.
Refer to Wiring Schematic 9
(Page 53) for digital display module.
• Digital display module master/slave
Two panels may be connected
together so digital display module
pressure reading(s) of first panel will
be duplicated at second panel.
Two conductors for each digital display
module must be routed from first
alarm panel to second alarm panel.
Refer to Wiring Schematic 6
(Page 51).
• Ethernet
An eight conductor category 5 network
cable is required between each alarm
panel to be networked and a facility's
Ethernet hub or switch.
