INTRODUCTION
Hochiki modular design HRA-1000 Series Remote Multiplex Annunciator panels provides a large capacity of annunciation (up
to 224 points) with standard Hochiki Series 1000 Fire Alarm Control Panels. The HRAM-1032 Main Annunciator Chassis is a
32 Circuit, Annunciator which may be expanded with up to four HRAX-1048 Adder Annunciator Chassis to a maximum of 224
Circuit Display Points. Each Circuit Indicator is a bi-color LED that is automatically configured to match the Fire Alarm Control
Panel configuration. There are five types of enclosures available: the HBB-1001, HBB-1002 and HBB-1003 which can take 1,2,3
chassis resp ectively.
INSTALLATION INSTRUCTION
Note that the HRAM-1032 is supplied with the NP-680 Laser Printable Label Sheet. Column 1A or 1B (English or
French) is selected for 2-Stage or 1-Stage Systems respectively. Column 3 is discarded and the last four colum ns are
filled with the blanks after they have been printed. The HRAX-1048 is supplied with the NP-681 Blank Las er Printable
Label Sheet.
NOTE: The HRA-1000 normally displays Initiating Circuit Status (no individual circuit troubles) only. Indicating and
Relay Circuits are not remotely displayed. See the Fire Alarm Control Panel Manual for more details.

WIRING INSTRUCTION
The RS-485 Wiring to the RAM-1032 Module
needs to be Twisted Shielded Pair as shown in the
diagram. The wire gauge may be ...
22 AWG up to 2000 ft.
20 AWG up to 4000 ft.
18 AWG up to 8000 ft.
The RS-485 wiring from the Fire Alarm Control
Panel to the Annunciator(s) must be point-to-point
from the FA Panel to the first Annunciator, then the
next Annunciator, and so on. No star-wiring or T-
tapping is allowed.
Each HRAM-1032 Annunciator Module has a 120
ohm End-of-Line Resistor onboard for
termination (via JW6) of the RS-485. This JW6
jumper is removed on all except the last wired
Module.
The 24 VDC field wiring needs to be of an
appropriate gauge for the number of annunciators
and the total wiring run length. See the
Specifications section “Current Drain for Battery
Calculations”, and calculate the Maximum current
for all Annunciators summed together ...
NOTE: Accidentally connecting any of the 24 VDC wires to the RS-485 wiring could result in damage to the HRAM-
1032/16 and/or to the Fire Alarm Control Panel that it is connected to !!!

DIP SWITCH SETTINGS & CABLING
Each Annunciator Asse m bly (M ain and Add er Chassis ’) ne eds to be assigned a unique, s equential “Address” via the
Main Chass is DIP Switch S W 1. DIP Switch SW 2 is used to allow disabling of some Front Panel push buttons (when
individual sw itches are “ON” then the correspon ding push bu tton is disabled).
The H RAM-103 2 DIP Switch es are set as ...
SW1-1 = Address A0 SW2-1 = Disable System Reset Button
SW1-2 = Address A1 SW2-2 = Disable Fire Drill Button
SW1-3 = Address A2 SW2-3 = Disable Acknowledge Button
SW1-4 = Address A3 SW2-4 = Disable General Alarm Button
SW1-5 = Not Used SW2-5 = Not Used
SW1-6 = Not Used SW2-6 = Disable Auxiliary Disconnect Button
SW1-7 = Not Used SW2-7 = Not Used
SW1-8 = Not Used SW2-8 = Disable Signal Silence Button
The An nun ciator “Addres s” (see the Manual for the Fire Alarm Control Pane l being used), is se t as ...

SW1-4 (A3) off off off off off off off on on on on on on on on
Annunciators on a common RS-485 connection must
be numbered sequentially; i.e.: 1,2,3,4, and not
randomly suc h as 5,3,8,14 !! Note that not all
Annunciator “Addresses” are valid fo r all Fire Alarm
Control Panels. Refer to the Fire Alarm Control Panel
Manual for further information.

Chassis, or to the previous Adder
Annunciator Chassis.
P2 - Connects to the next Adde r
Annunciator Chassis.

Current Drain for Battery Calculations:
The maximum normal current drain will be during Lamp Test when all lamps are illuminated on one chassis at a
time. Thus the currents are ...
Normal Standby = 50 mA + ______________ X 15 mA = _________
Maximum = 150 mA + ______________ X 15 mA = _________
The Normal Standby Current is used for Battery Size Calculations (see the Fire Alarm Control Panel manual) and
includes the current drain for the Trouble Buzzer, Trouble LED, and one Alarm LED. The Maximum Current is used
to calculate the wire size (see the Wiring Instruction).
