Wiring (Cont.)

Ethernet

Alarms can be connected together in a
TotalAlert alarm network.
Connect the network cable modular plug to
annunciator module modular jack J9.

Building Automation System

TotalAlert 2 master and combo alarm
panels are compatible with Johnson
Controls Metasys® N2 building
automation system.
Each alarm panel is field programmed
with a unique N2 address.
Using this address, Johnson Controls
system can monitor alarm panel status
including digital pressure readings and
programmed alarm set points.
Each alarm panel is connected to a
common two-wire RS-485 serial computer
interface bus. Two wires are connected
to connector TB1 of annunciator module
and then connected to common data bus.
Refer to Wiring Schematic 11 (Page 55).

NOTE:
The following information is intended to be
used by Information Sytems or Building
Automation personnel.
The state of each of the 64 switched
inputs of a master or combo alarm is
available using BI1 through BI64.
BI65 is true if there are any active alarms.
For efficient single point monitoring, enroll
BI65 in the BAS polling table.
BI66 indicates the state of the audible
alarm.
Additional information is available using
integer data points ADI1 through ADI5.
ADI1 = device serial number, low 2 bytes.
ADI2 = device serial number, high 2
bytes.
