Introduction
Chapter 1: Introduction

NOTE:
Hill-Rom recommends using a separate pair of wires for each input to the
Master Alarm. Also, even if the network communications option (alarm Web
page accessibility) is not initially selected, run Cat-5 Ethernet cable to each
rough-in assembly. It will cost the facility more to run the cable after
installation.

2. Master Alarm Rough-In—The Master Alarm Rough-In Assembly
provides connections for field wiring to the power supply and incoming
source signals to the Breakout P.C. Board. It is installed prior to the dry
wall installation and finishing.

3. Master Alarm Front Panel—The Master Alarm Front Panel houses the
Master Alarm Module. It consists of the finish trim plate and hinged door
assembly that mounts to the Master Alarm Rough-In Assembly.

4. Master Alarm Module—The Master Alarm Module monitors discrete
inputs from source equipment and; if the Network Communications Board
is installed in the Area Alarm, the Area Alarm Modules. When any errors
or faults occur, it informs the facility’s staff immediately with both audible
and visual indications.

5. Master Alarm Breakout P.C. Board—The Master Alarm Breakout P.C.
Board interfaces with the source equipment field wiring, two dry-contact
relays that can be used as outputs, and one dry-contact relay that can
interface with conventional building automation equipment. This Master
Alarm Breakout P.C. Board is located in the Master Alarm Rough-In.

6. Area Alarm (Local Emergency Alarm)—The Area Alarm contains
between one and six gas-specific Area Alarm Modules that monitor and
display the actual pressure or vacuum of gas lines within the facility. The
Area Alarm consists of the Area Alarm Front Panel and the Area Alarm
Rough-In.
There is one dry-contact relay in the Area Alarm that provides an output
signal. The output can be wired to either the normally-closed or normally-
open contacts. It is located on the Area Alarm Breakout P.C. Board, and
marked MAIN ALARM. For wiring diagrams, refer to the foldouts at the
rear of this manual.
• MAIN ALARM RELAY

• When the Master Alarm is in alarm condition, this relay activates.

• When the Master Alarm is silenced, this relay stays activated.

• When the Master Alarm condition is remedied, this relay deactivates.
