instructions should be retained for future reference.

Heed Warnings - All warnings on the appliance and in the

operating instructions should be adhered to.

Follow Instructions - All operating and use instructions

should be followed.

Water and Moisture - The appliance should not be used

near water - for example: near bathtub, washbowl, kitchen

appliance is not defeated.

Power Lines - An outdoor antenna should be located

away from power lines.

Outdoor Antenna Grounding - If an outside antenna

is connected to the receiver, be sure the antenna system

is grounded so as to provide some protection against

voltage surges and built up static charges. Section 810

of the National Electrical Code, ANSI/NFPA No. 70 1984,

provides information with respect to proper grounding of

the mast and supporting structure, grounding of the lead

in wire to an antenna discharge unit, size of grounding

conductors, location of antenna discharge unit, connection

to grounding electrodes, and requirements for the

grounding electrode (see ﬁ gure).

Object and Liquid Entry - Never push objects of any

kind into this product through openings as they may touch

dangerous voltage points or short out parts that could

result in a ﬁ re or electric shock. Never spill liquid of any

kind on the product.

Servicing - The user should not attempt to service

the appliance beyond that described in the operating

instructions. All other servicing should be referred to

qualiﬁ ed service personnel.

Damage Requiring Service - The appliance should be

serviced by qualiﬁ ed service personnel when:

■ The power supply cord or the plug has been

damaged; or

■ Objects have fallen, or liquid has been spilled

into the appliance; or

■ The appliance has been exposed to rain; or the

appliance does not appear to operate normally

or exhibits a marked change in performance; or

■ The appliance has been dropped, or the

enclosure damaged.

■ When the product exhibits a distinct change in

performance - this indicates a need for service.

Replacement Parts - When replacement parts are

required, be sure the service technician has used

replacement parts speciﬁ ed by the manufacturer or have

the same characteristics as the original part. Unauthorized

substitutions may result in ﬁ re, electric shock, or other

hazards.

Safety Check - Upon completion of any service or repairs

to this product, ask the service technician to perform safety

checks to determine that the product is in proper operating

condition.

Wall or Ceiling Mounting - The product should be

mounted to a wall or ceiling only as recommended by the

The following tools are required for the DMC3-4 installation. You may not need to use all these tools on each install but having then handy will make the overall installation process easier.
PAGE 4
DEVELOP THE JOB ESTIMATE It is critical that you determine the complexity of each retrofit installation prior to developing the job estimate. It is hard to predict all the unique situations you will encounter in the field. For this reason M&S Systems recommends you visit each retrofit site prior to developing a job estimate and ordering equipment.
PAGE 5
INSTALLING THE WALL HOUSING WALL STUD The DMC1H and DMC1HC housings are designed for 16” on center studs. You may encounter stud spacings that vary from this standard. DMC1H WALL HOUSING • Use the DMC1H housing when you are replacing an existing system with an intercom only system. • The DMC1HC housing is used for combination systems only – or those that include the DMC3-4 master and the optional DMCMP3 CD/MP3 player. Locate the DMC1H or DMC1HC (combo) wall housing between the studs (see Figures 2 & 3).
PAGE 6
TRANSFORMER INSTALLATION The Model TE5D transformer powers the DMC3-4 Master Station. The Model TE2D transformer powers the optional DMCMP3 CD/MP3 Player. Both transformers are supplied in a small metal enclosures that mount in the bottom of the wall housing. INSTALL TRANSFORMER FROM INSIDE WALL HOUSING WALL HOUSING (DMC1H SHOWN) WARNING ALL AC ELECTRICAL CONNECTIONS TO THE POWER SOURCE AND THE TRANSFORMER(S) MUST BE MADE BY A LICENSED ELECTRICIAN AND MUST OBSERVE ALL NATIONAL AND LOCAL ELECTRICAL CODES.
PAGE 7
REPLACING THE ROOM STATIONS ATTACH A DMCFR RETROFIT MOUNTING PLATE TO THE EXISTING ROOM STATION ROUGH-IN BOX The DMC room and door speakers use the existing wire and speaker rough-in mounting frames or boxes. To replace the speaker, first remove the old speaker. Leave the existing room or door station mounting rings in place. After removing the room station verify the integrity of the wire run. Then install the mounting plate from the DMCFR (finish-out frame for room stations).
PAGE 8
REPLACING PATIO STATIONS Do not remove the existing patio station rough-in. The DMC3-4 retrofit system is designed to fit into the existing enclosure. It is important to note that M&S patio stations are weather resistant not water proof. M&S patio stations should not be located in an area that is in direct line of water from sprinklers, rain or other devices such as power washers. Please use the DMCFRW finish-out frame in outdoor and high sun areas.
PAGE 9
INSTALLING THE CHIME MODULE Install the optional chime module MC3 or MC8 in the wall housing by pressing the chime module over the four plastic standoffs attached to the wall housing as shown in Figure 12. The DMC3-4 supports the 3-note Model MC3 and 8-note Model MC8 chime modules. The chime module installs inside the wall housing and is activated by the Door Station pushbutton. 1. Install the chime module circuit board by snapping it onto the four plastic mounting standoffs in the wall housing. 2.
PAGE 10
INSTALLING THE DMC3-4 3-wire or 4-wire Configuration Jumper Setting The DMC3-4 ships configured for a 3-wire retrofit system. If you are replacing a 4-wire system you must change the jumper setup on the DMC3-4 Master Station. The jumper change must be completed before any cables are connected. To change the jumpers pull them off the 3-wire connector pins and place them onto the 4-wire connector pins (see Figure 14).
PAGE 11
Chime Connections Plug in the modular chime plug to the 4-pin connector labeled as CHIME on the DMC3-4 Master Station (see Figure 17). Optional Door Release Connections Connect the door release wires from each cable to the terminals marked DOOR RELEASE on the DMC3-4 Master Station (see Figure 18). Antenna Connections The number and style of antenna leads will vary based on the intercom system being replaced. The DMC3-4 system is designed to use the existing antenna.
PAGE 12
Mounting in a Master Station Only Installation When the DMC3-4 Master Station is used without the optional CD/MP3 Player, the DMC3-4 mounts inside the DMC1H wall housing. BE SURE THE AREA IN THE WALL HOUSING BEHIND THE MASTER IS CLEAR OF CABLES Follow these steps for mounting the Master Station. 1. Verify that the circuit breaker controlling the power to the wall housing transformer is OFF. 2.
PAGE 13
Mounting the Master with the Optional DMCMP3 Player (continued) 9. Insert the CD Player interface cable into the INTERFACE connector on the CD Player (see Figure 24). 10. Insert the CD audio cable’s BLACK RCA plug into the AUDIO LEFT jack on the CD Player, then insert the cable’s RED RCA plug into the AUDIO RIGHT jack on the CD Player (see Figure 24). 11. Plug the connector from the TE2D power transformer in the wall housing to the CD Player’s POWER connector (see Figure 25). 12.
