BOSCH HMB

Installation Instructions

OVERVIEW - Engineer’s Specification

The BOSCH HMB system shall include one Master Panel and one or more Distributed

Panels. The system shall be microprocessor based, and shall be compatible for use with

contact closures from the Fire Alarm Control Panel, (FACP). The system shall have a high-

speed communication bus and have the capacity for 6 channels of combined audio and data

on a single pair of wires. The field wiring for the communication bus may be configured for

either Style 4 or Style 7 supervision. The system shall have the capacity for Fire Fighters

Phone communication. The system shall have a minimum capacity of 2048 monitor and

control points.

The Master Panel shall contain an integral microphone, dual channel digital message

repeater, (DMR) and digital tone generator, 120 VAC power supply, and battery charger. The

system shall be modular in design, and shall be expandable such that additional system

control points may be configured. The system shall include integral self-diagnostic routines

that shall continually monitor system status, and shall indicate the precise type of trouble

conditions should they occur in the system. A trouble condition within the system shall cause

a trouble indication to be transmitted to the FACP.

Distributed panels shall provide a minimum of 4 Class "B" (Style Y) speaker circuits,

expandable to eight total. Alternately, panel may be configured for 4 Class "A" (Style Z)

speaker circuits. Panel will provide up to 6 simultaneous audio channels, up to 16 Fire

Phone circuits. Amplifiers will contain their own power supplies, battery chargers and provide

auxiliary power for other components. Speaker circuits shall be supervised for short and open

circuit conditions, and shall be able to withstand transient or continuous short-circuit

conditions without damage to the system.

System may be configured for General Alarm All Call operation, Alarm by Zone or

Floor Above / Floor Below as required. Contact closures shall allow immediate broadcast of

an alarm signal and evacuation message to the appropriate area. Non-Alarm areas may

receive alert tones and messages as required or activated by the FACP.

The alarm signal/evacuation message shall be broadcast until the FACP is reset, or until

emergency personnel interrupt the broadcast with a manual page.

To prevent unauthorized tampering, the voice evacuation system shall disable the

microphone if the microphone is keyed continuously for 3 minutes or more. Systems that do

not have this feature shall not be acceptable.

INSTALLATION

Installer must insure that all wiring and devices installed in system meet the following standards:

National Electrical Code (NFPA 70)

NFPA Standard 72

Life Safety Code (NFPA 101)

Install equipment in a clean, dry environment, avoid installation where equipment could be subjected

to vibration. ** Make sure all cabling is separated from Non-Power Limited Power Limited

cabling.**

WIRING (Refer to wiring and terminal designation diagrams)

MASTER PANEL

1. Connect Netcom Bus between all panels. Maximum distance between panels is 4000’ (min 16

AWG) or 120 Ohms max. Impedance. See page 5 for wire type.

2. Connect AC power to master panel and then connect batteries.

3. Once power is on to the unit, connect battery wiring harness from the PWR power supply board TB-

1 Red (+) / Black (-). Observe polarity. Minimum battery size is 7AHr. (Max 24 Ahr in a separate

Battery cabinet) (use 2 12V batteries connected in series) *See Master panel wiring diagram on page

6. *

NOTE: Wiring for batteries and 120 VAC is Non Power-Limited. Care must be taken to insure that all

Power-Limited wiring maintain a minimum spacing of ¼" from any Non Power-Limited wiring. If

batteries must be located in separate enclosure, provide separate conduit run for battery wiring only.

DISTRIBUTED PANELS

(Maximum number of Distributed Panels is 250 on a system)

1.Speaker circuits require an End of Line resistor for supervision. Attach a “reference value” EOLR for

the speaker circuits to TB9 - 1 & 2 on MBR board. This value must be placed at the end of the speaker

line as well. The system is shipped from the factory with 10kOhm ½ watt EOLR.

2. Connect all speaker loops (UL listed devices) to TB1 - TB4 along the top edge of the MBR mother

board in the Distributed panels. Fire Phone circuit connects to TB5.-TB6 on the left side of the MBR

Motherboard in the Distributed panels.

3. Connect 120 VAC, 60 Hz, power to the black and white pigtail leads from transformer primary.

Secure ground lead to grounding stud in cabinet located on the backplate.

4. Once all power and circuits are connected,

he Green LED will remain on to indicate that the HMB system is

fully operational and all circuits are nominal. Observe the display during the reset, it will show how

many DP in the loop.

BATTERY MAINTENANCE

Typical battery life is approximately 3-5 years depending on usage. Always replace both

batteries with same amp hour ratings and of approximately the same age. Refer to the battery

manufacturer's specifications for the particular battery used.

initiate a 'Global Reset' This is done by holding the "Fault

Silence' switch in the up position while the 'System Reset' switch is clicked twice. This will rerun the

'Power On Diagnostics' program. T

Please read this Manual completely before installing the HMB System.

System Operation

**Note** ALL panels in system are pre-programmed at the factory

Alarm When an input on the MX-II FACP Interface card is pulled down to circuit common

(0VDC), the Evacuation Signal and Message will be broadcast into the selected Evacuation

Zone. If 'Floor-Above/Floor-Below' has been enabled, the Evacuation Zone for the floor above

and the floor below the selected zone(s) will also be activated.

The floor(s) receiving the Alarm Tone/Message is displayed by a slow (2 second) flashing of the

LED associated with the Evacuation Zone on the Paging Control panel.

If 'Set Alert Non Fire Floors' has been enabled in programming, all floors not broadcasting the

Evacuation Signal and Message will begin broadcasting the Alert Signal and Message.

In addition, if the paging microphone is used and no Evacuation/Paging Zones have been

manually selected, paging will automatically be routed to those zones that are in alarm. The

Evacuation Signal will resume when paging is ended as will the Evacuation Message.

If an Evacuation/Paging Zone is selected manually, paging will take place in the selected zone,

or zones, only (operation if system was designed as “dual” channel)..

Within a single Distributed Panel, and due to the nature of Dual Channel systems using one

amplifier per channel, paging into an Evacuation/Paging Zone broadcasting the Alert Signal and

Message will silence the other zones also broadcasting the Alert Signal and Message if there is

also a zone broadcasting the Alarm Signal and Message. In other words, within a single

Distributed panel only two audible signals can be broadcast at one time, either Alarm and Alert

Signals, Alarm Signal and Paging or Alert Signal and Paging.

Paging When an Evacuation/Paging Zone is selected by the operator using the associated

switches on the Paging Control panel, the LED(s) will indicate which zone(s) have been selected.

The All-Call switch on the HMB Control panel will select all zones for paging when clicked once.

A second click of the All-Call switch will deselect all zones.

The Zone Selection switches indicate which zones have been selected for paging. Broadcast of

live voice messages does not take place until the Push-to-Talk switch on the microphone is

pressed.

Fire Phone When a Fire Phone Handset is plugged into a Fire Phone Jack, the LED on the Zone

Control panel associated with that Fire Phone zone will start flashing. A ringing signal will be

heard to indicate that a handset has been jacked in. The ringing signal will cease when the Fire

Phone Zone is selected.

Normally, only one Fire Phone Zone is selected at a time. Selecting another zone where a

handset is jacked in will deselect the other zone(s).
