HT3011 ReliaBUS™ Series Inside Handset

Intercom Stations used with the SP300

Control Unit and STR™ TSMB Series

Modular Style Door Entry Station

Installation and Use Instructions

APPLICATION

The HT3011 ReliaBUS™ series intercom system allows
up to 120 HT3011 inside handset stations to communicate
with one or two STR™ modular type door entry stations,
and to release the door opener at each door entry station.
A number of optional accessories are available to provide
a complete entry intercom signaling and communications
system. The HT3011 ReliaBUS™ system requires only
two (2) common 'bus' wires to the remote apt. handsets.
Up to four (4) handsets may be used in parallel in each
apartment/suite (see special notes on page 4).

PROCEDURE

1. Read installation instructions for each unit to deter­mine equipment location and installation method.

2. Install housings and wiring.

3. Install equipment.

4. Check wiring and connect. Observe all local and
national electrical and building codes.

5. Apply power and check operation.

HOUSING INSTALLATION AND

EQUIPMENT LOCATION

INSIDE HANDSET STATIONS
Locate handset stations where needed, at convenient
speaking height, about 4.5 feet (137cm) from the finished
floor. Handset can be secured directly to the finished wall
surface or can be mounted over a single gang electrical
'gem' box or single gang electrical plaster ring.

OUTSIDE STATION(S)
Locate door station(s) at convenient speaking height on
exterior wall near entrance. Door stations must be the
correct TSMB (or equivalent) 'modular' type speaker and
electret condenser microphone installed.

SP300 / SP300E CONTROL UNIT(s)
The SP300 and SP300E (if used) are usually located in
a separate equipment location. You can mount the SP300/
SP300E by using the provided plastic 'DIN RAIL' mount­ing strip. Locate the SP300/SP300E away from any
source of direct heat or extreme cold and in an accessible
location. Keep at least 3 feet (1 meter) away from
transformers, light dimmers or other electrical devices or
wiring or sources of electrical interference.

TRANSFORMER/POWER SUPPLY
The NTR211 transformer/power supply should be in­stalled near an accessible source of 117VAC, preferably
within 50' (15 meters) of the SP300, but no closer than 3
feet (1 meter) from the SP300 control unit. Connect the
NTR211 to the 117VAC power by means of an electrical
cord and plug.

DUAL ENTRY ADAPTOR
For dual entrance installations, no multi-entrance adap­tors are required. The HT3011 ReliaBUS™ system has
built in intelligence and electronics that can automatically
determine which door entry station placed a call to the
apt. handset, and the system will automatically switch the
voice and door release functions to the calling entrance.

The DO-001A (or equivalent 12VAC type) electric door
release is installed in the door jamb in place of the regular
door strike plate, at each entry door.

WIRING

INSIDE HANDSET STATIONS
Run 2 conductor (common) #22AWG cable from station
to station and to the SP300 control unit. Additional cables
may be used to serve other stations on other risers (lines).
Cables may be straight or twisted pair type and may be
solid or stranded conductors. Polarity is not important.

Route cable away from AC power wiring, transformers,
fluorescent lights, light dimmers or other electrical de­vices. Protect cable from damage. Shielded cable should
be used if AC interference is a concern, or if cables
cannot be run adequately spaced away from any source
of electrical interference.

DOOR ENTRY STATION(s)
Run 2 conductor #22AWG (bus) cable from TSMB
speaker/microphone module to the SP300 control unit. If
the SP300 control unit is not mounted behind the entry
door station, and is mounted remotely, we recommend
using shielded cable from the speaker/microphone mod­ule to the SP300 control unit. Route cable away from
inside station cable, AC power wiring, transformers,
fluorescent lights, light dimmers and other electrical
devices. Protect cable from damage. Shielded cable
should be used if AC interference is a concern.

AWD089 Rev. 2 (11/04)

If you wish to have the door entry station(s) illuminated, run
a separate 2-conductor #22AWG cable from the NTR211
power supply (8V output terminals) to the door entry station
terminals '0' and '8V' (at each door station).

DOOR RELEASE
Run 2 conductor #18AWG from the electric door release
location to the SP300 control unit. If distance is greater than
50 feet, use #16AWG cable.
intercom cable, and route away from any intercom wiring.

CONNECTIONS
Before connecting, make certain wires are free from shorts
or grounds. Make connections as shown on following pages
and as detailed in the following instructions.

INSIDE HANDSET STATIONS

1. Connect the two (2) common 'bus' wires to the two (2)
handset terminals marked 'BUS'. Polarity is not important
on these two (2) wires.

2. Terminals 'ET' on each handset station are optional
terminals, and only used if you have a momentary low­voltage pushbutton outside of each apartment's entry
door, to provide a 2nd signal indicating that the visitor is
at the individual apt. door.

DOOR ENTRY STATION(s)

1. Connect the two (2) terminals marked 'BUS' on each
TSMB speaker/microphone module to the two terminals
marked 'BUS' (and ground) on the SP300 control unit.
There are two (2) sets of terminals marked 'BUS' (and
ground) on the SP300 control unit. You can use either set
to connect to the door station(s) and/or to the inside
handsets. 'BUS' wiring polarity does not matter!

Use a separate cable from the

FINISH INSTALLATION

1. Install stations on housings. Do not overtighten screws.

2. Install SP300 (and SP300E) control unit(s) and acces­sory devices as needed.

3. Connect NTR211 power supply to 117VAC. Observe
all local and national electrical and building codes.

TEST AND CHECKOUT

1. At all inside handset stations,
hung-up and seated properly on the cradle switch, and
that no wires were 'pinched' when handset covers were
secured.

2. Check each unit in the system for operation in accor­dance with the operating instructions.

3. If feedback occurs between stations, reduce volume.
Speaker/microphone volume controls are preset at the
factory, but may be readjusted, if necessary.

OPERATING INSTRUCTIONS

(USED ONLY AFTER SYSTEM IS

PROGRAMMED - SEE PAGE 5 FOR

FULL PROGRAMMING INSTRUCTIONS!!)

OUTSIDE DOOR ENTRY STATION
TO CALL HANDSET: Push button on outside door entry
station to signal inside handset. An electronic tone will be
heard at the inside handset station, indicating that a visitor is
at the building entrance, and wishes to be let in.

make sure all handsets are

POWER SUPPLY

1. Using the provided cable that comes with the NTR211
power supply, plug the NTR211 into the SP300 control
unit. Do not force the connectors, as they are polarized to
plug-in to the SP300 in only one direction.

2. Do not connect the NTR211 transformer primary to
117VAC until entire installation is complete and checked.

DOOR OPENER

1. Connect the two (2) wires from 12VAC door opener #1
(at entrance #1) to SP300 terminals 'TO' only.

2. Connect the two (2) wires from 12VAC door opener #2
(at entrance #2) to SP300 terminals 'LT' only, if a second
door entry station is being used.

NOTE: POLARITY OF AC TYPE DOOR
OPENER TERMINALS IS NOT CRITICAL, BUT
DOOR OPENER MUST BE 12VAC (MAXIMUM
1A) TYPE ONLY.

INSIDE HANDSET STATIONS
TO REPLY: Lift the inside handset off of its cradle (within
45 seconds of being called) and speak in a normal voice.
Conversation is duplex type (digitally switched for talk and
listen). If satisfied with the identity of the caller, you may
depress the 'Key Symbol' push-button to electrically open
the entrance door (if so equipped). An AC type door opener
will 'buzz' while operating, indicating permission to enter.
When conversation is completed, hang-up handset on its
cradle. For your safety and the safety of your fellow
residents, do not 'buzz' in any visitors that you cannot
positively identify, or that do not belong inside the building.

OUTSIDE APT. DOOR (if so equipped and wired)
TO CALL HANDSET: Push button outside individual apt.
door to signal inside handset. A different electronic tone will
be heard at the inside handset station, indicating that visitor
is at your apt. door. Go to your apt. door and greet your
visitor(s).

TROUBLESHOOTING

If the system fails to operate as required, review operating
instructions again and check the following points:

1. ENTIRE SYSTEM DEAD: Check wiring between

NTR211 transformer and SP300 control unit; plug-in
connector at control unit and for 117VAC at NTR211
transformer primary.

2. NO CALL UP SIGNAL AT HANDSET: Check that

the programming for that specific apt. handset to that
entry door station pushbutton has been done properly, by
re-programming (see page 5).

3 . NO VOICE ON SYSTEM: Check volume controls

(potentiometers P1 and P2) on TSMB speaker/micro­phone module (in both directions; up and down).

Wiring is being run next to wiring for other systems and/
or devices, and/or door strikes.

6. SQUEALING OR HOWLING: Check TSMB

speaker/microphone volume control(s) set too high;
check for loose or damaged speaker/microphone mod­ule components at door entry station(s).

7. UNABLE TO TALK TO DOOR STATION: Check

TSMB speaker/microphone volume control(s) set too
low; check for loose or damaged speaker/microphone
module components at door entry station(s).

8. UNABLE TO LISTEN TO DOOR STATION:

Check TSMB speaker/microphone volume control(s)
set too low; check for loose or damaged speaker/
microphone module components at door entry station(s).

4 . UNABLE TO RELEASE DOOR STRIKE: Check

operating voltage of door opener matches 12VAC
output from SP300 system control unit. Check wiring
(and gauge) to door opener, from SP300 control unit.
When using a magnetic type lock or other 'fail-safe' type
door lock, you should use a reversing relay, such as our
model# PK407A for each entrance.

5 . HUM OR BUZZ: Check system wiring installed too

close to power wiring or electrical devices or transform­ers; check transformer(s) installed too close to control
equipment (should be at least three (3) feet away).

SPECIAL NOTES CONCERNING

GENERAL SYSTEM WIRING AND

USING MUL TIPLE HT3011 HANDSETS

IN P ARALLEL IN 1 APARTMENT

1. The 2-conductor wiring running to the HT3011 handsets
can be solid or stranded, twisted pair or straight type,
although twisted pair is recommended. It is important that
you only use 2 wires to the 'BUS' terminals and
double up conductors to achieve a heavier wire gauge!

2. You can use up to four (4) HT3011 handsets to be signaled
from an individual door entry pushbutton, in one apartment/
suite. When using more than one (1) HT3011 (in parallel) in
each apartment, there are a few things you need to know; (a)
each HT3011 in that apartment must have its IC (chip)
replaced with one from a matched set. For 2 handsets use
optional chip set #29002, for 3 handsets use optional chip set
#29003 and for 4 handsets use optional chip set #29004. (b)
unplug the existing IC Chip, and replace it with one from the
matched set (see page 4 diagram), being careful not to bend
the pins, (c) make sure to replace all of the IC chip sets into
all of the HT3011 handsets being called in parallel BEFORE

DO NOT

9 . MISC. INFORMATION: To check the SP300 out-

put, using a DC volt meter, check the voltage across the
'BUS' output terminals. You should see approx. 20VDC
to 21VDC with the apt. handsets connected, and hung­up. You should see approx. 24VDC with nothing con­nected except for the NTR211 power supply/trans­former. If the voltages do not fall within these ranges, try
replacing the SP300 control unit.

If these checkpoints fail to indicate the problem, there
may be an equipment fault. Contact the factory or a
qualified service representative.

PROGRAMMING those handsets to the pushbutton at the
door entry station(s), (d) when a visitor calls to an apartment
with multiple HT3011 handsets, they will chime in sequence
(i.e. 1 then 2 then 3 then 4). You will not be able to pick up
any of the handsets to speak, or release the electric door
strike, until ALL of the handsets have gone through their
chiming sequence.

3. The wiring going to the electric door release(s) MUST be
in a separate jacketed cable from any of the intercom and/
or 'BUS' or 8VAC illuminator wiring. Try to keep this wiring
as far away from the other system wiring as possible.

4. When using more than 40 and up to 120 HT3011 handsets,
you must use the SP300E (Expander) unit in addition to the
SP300 control unit. The SP300E does not require any
additional power and is powered from the SP300 using the
jumper wiring harness provided. When using the SP300E, do
not connect any of the HT3011 handsets to the 'BUS'
terminals on the SP300, but only to the 'BUS' terminals on the
SP300E (30 maximum for each of 4 output 'BUS' lines).

5. When using any shielded cables, do not connect the shields
or drain wires. Leave the shield connections "floating".

PC Board Inside HT3011 Handset

NOTES: When connecting multiple
HT3011 Handsets (in parallel) in one
apartment/suite, you must replace this
IC (chip) with one from a matched set of
2 (optional model #29002) or 3 (optional
model #29003) or 4 (optional model
#29004), before programming the hand­sets.

On the matched chip sets you will see
only one of the chips will have a single
black line (slash) on it, and the other
chip(s) will have multiple lines (slashes).
When programming the handset (on
page 5) you only need to program the
handset with the chip with the single
black line (slash). When using multiple
handsets in one apt. you must use pro­gramming option #1 (on page 5) only,
and not programming option #2!

SPECIAL NOTES CONCERNING

DIP SWITCH SETTINGS

ON THE SP300 CONTROL UNIT

and SP300E (Expander) if used

The SP300 has a 4-position DIP Switch on the upper right
hand corner, which sets the SP300 to a 'single' or 'dual'
entry station operation mode. See page 5 for dual entrance
entry panel programming instructions.

The SP300 comes set from the factory for 'single' entrance
operation. Make sure the DIP Switch is set correctly,
depending on whether you are using the SP300 with a
'single' or with 'dual' door entry stations, as shown on the
illustrations herein.
