Rev. B August 2000

Introduction To The Series DV-EM

The Digital Voice Expansion Module (Series DV-EM) provides thirty-two additional dry contact or open collector inputs for either the Series DV-100 or
Series DV-200 products.

Series DV-100 and Series DV-200 products come standard with eight contact inputs. When a Series DV-EM is used with a Series DV-100 or Series
DV-200 product, the eight standard contact inputs on the Series DV-100 or Series DV-200 product shall not be used.

CAUTION: When one or more Series DV-EM's are connected to a Series DV-100 or Series DV-200, any attempt to use the eight contact

inputs on the Series DV-100 or Series DV-200 will cause a trouble condition and may cause the system to malfunction.

A connector (J1) on the Series DV-100 and Series DV-200 products provides an interface for Series DV-EM products. Up to eight Series DV-EM's
can be connected to a Series DV-100 or Series DV-200 product. The eight Series DV-EM's shall be connected in a daisy chain configuration. An
illustration of the daisy chain configuration is shown in Figure 1 below.

As a Series DV-EM is connected to a Series DV-100 or Series DV-200 product, it is automatically assigned an address from one thru eight. The
address is defined by the location of a Series DV-EM in the daisy chain connected to a Series DV-100 or Series DV-200 series product. An
illustration of the address assignments is shown in Figure 1 below.

FIGURE 1.

As can be seen, the first Series DV-EM in the daisy chain is assigned address 1, the second Series DV-EM in the daisy chain is assigned address 2,
and so on. Table 1 illustrates the file that plays when a given contact input is activated on one of the eight Series DV-EM's.

Each one of the thirty two contact inputs is supervised. The contact input wiring is supervised with a LISTED 10K ohm end-of-line resistor. A 10K
ohm resistor is placed on the printed circuit board adjacent to each set of contact input terminals. If a contact input is used and its wiring supervised,
its resistor must be removed from the printed circuit board and a LISTED 10K end-of-line resistor installed at the end of the line (contact origination). If
a contact input is not used or used but does not require supervision, the resistor remains on the printed circuit board.

The Series DV-100 or Series DV-200 products should be connected to the first Series DV-EM in the daisy chain using a cable. The cable is
Wheelock Model CAB-EM. Successive Series DV-EM's may be connected directly together or have a cable between them. (The maximum length of
cable between each Series DV-EM is 3 feet.)

A block diagram of the Series DV-EM is shown in Figure 2. The Series DV-EM printed circuit board is shown in Figure 3.

Wheelock models; DV-100, DV-200, MDV-2, DX-100, DX-200, MDX-2 and DV-EM are UL 864 approved for use with Fire Alarm Control Panels (FACP).
The above models are used as accessory control units in UL 864 listed protective signaling systems. All models have an operating voltage range of

11.0-29.0VDC. All are operated by a serial port or contact closure with an adjustable output from 0.5-2.0VRMS.

DV-EM Manual Sheet 10 of 16
Rev. B August 2000

Wiring Guidelines

Although the Series DV-EM incorporates noise filtering circuitry on its input, induced voltages or noise on the input wiring can cause improper
operation. Therefore, use shielded twisted pair wire for all file input wiring. The audio output lines (and the auxiliary music input lines) should also be
wired with shielded twisted pair to minimize noise pick-up. For all other connections, twisted pair is recommended to reject common mode noise, but
shielding is optional.

The shield of each cable shall be connected only at one end. Each shield of each cable that connects to the Series DV-EM is to connect to the
ground bus bar. The green ground screw on the DV-EM printed circuit board shall also be connected to the ground bus bar. The ground bus bar
shall be connected to earth ground.

WARNING: ALL SERIES DV-EM WIRING SHOULD BE ROUTED AWAY FROM ANY HIGH VOLTAGE OR HIGH CURRENT LINES (SUCH AS

AC OR DC POWER LINE, AUDIO POWER LINES, AND MOTOR OR RELAY ACTUATION LINES). THE SERIES DV-EM WIRING
SHOULD NEVER BE INSTALLED IN THE SAME CONDUIT WITH HIGH VOLTAGE OR HIGH CURRENT LINES.

The National Electrical Code defines two types of circuits for protective signaling systems: power limited circuits and non-power limited
circuits. Series DV-EM input circuits have been designed as power limited circuits.

CAUTION: The National Electric Code limits the maximum number of conductors that can be installed in conduit and wiring boxes depending

on the size of the conduit, the volume of the boxes, and the gauge of the wire used. Make sure that wiring used for Series DV­EM installation complies with the latest NEC requirements for power limited circuits.

CAUTION: If auxiliary music input is connected to the Series DV-EM, then the music source must be power limited.

See the Series DV-EM Field Wiring Connection section of this manual for recommended wire sizes and wire type to use for all Series DV-EM input
lines.

Mounting

The Series DV-EM shall be mounted in a location within the environmental limits specified in the latest UL Standard for indoor control panels. The
Series DV-EM shall not be located in a hazardous location. Refer to the "Technical Specifications'' section.

CAUTION: In order to comply with the latest NFPA and UL requirements for interconnection of fire alarm control equipment, the Series DV-EM

units must be located in the same room as, and within 20 feet of, a LISTED compatible fire alarm audio system with the wiring
enclosed in conduit and properly connected to such panel.

Refer to Figure 4 for Series DV-EM mounting hole layout. Drill mounting holes for appropriate screws and anchors to ensure secure mounting to the
type of surface at the selected location. Keep out dust and dirt during installation. Dust and dirt can interfere with the operation and reduce the life
of the equipment.

Remove the cover and mount the Series DV-EM at the selected location. Use care to avoid damage to the PC board during installation. Do
not apply excessive pressure to the PC board or its components, including field wiring terminals and connectors.

WHEELOCK'S LIABILITY ON ANY CLAIM OF ANY KIND, INCLUDING NEGLIGENCE AND BREACH OF WARRANTY, FOR ANY LOSS OR DAMAGE
RESULTING FROM, ARISING OUT OF, OR CONNECTED WITH THIS CONTRACT, OR FROM THE MANUFACTURE, SALE, DELIVERY, RESALE, REPAIR
OR USE OF ANY PRODUCT COVERED BY THIS ORDER SHALL BE LIMITED TO THE PRICE APPLICABLE TO THE PRODUCT OR PART THEREOF WHICH
