DW-IP2 housing structure and material ensure its protect unit elements of dust, foreign
matter and water ingress and etc. DW-IP2 housing and handset (in corresponding versions)
are made of special-purpose UF-resistant fiber-glass reinforced polyester resin.
Rubber gasket seals under the cover, integrated loudspeaker, and microphone, two-
way toggle, as well as in cables glands of DW-IP2 ensure its IP66 ingress protection rating
as per GOST 14254-2015 (IEC 60529:2013).
Integrated loudspeaker has a diaphragm that is resistant to moisture and vapors of
aggressive chemicals. The use of contactless (optical) pairs as sensitive elements of toggle
switches prevents sparks and bad contact due to corrosion. To this end, pushbuttons and
dial pad are sealed with rubber gasket. A porous silicone cord with a diameter of 3 mm is
placed in the groove around the cover.
All of the above-mentioned enables to operate the product regardless of its version in
administrative facilities, in open space and (or) in facilities with high levels of humidity, noise,
dust and temperature, as well as presence of smoke, corrosive gases and chemical vapors in
the air.
DW-IP2 contains embedded software and configuration data stored in RОM, which
allows it to communicate with other digital communication system users directly, handle
priority connections and manage communication and indication modes. An IP-network built
using standard network equipment is used to facilitate communication.
Within the digital intercom system IPN, DW-IP2 provides the following functions:
−Armtel-IP, SIP and SNMP protocol support;

−individual simplex communication via SIP and Armtel-IP protocols;
−half-duplex (manual control) communication via SIP protocol;
−indication of busy call, incoming and outgoing calls, unanswered call notification
on direct buttons;
−free programming of the direct buttons (up to 24 pcs.);
−voice message recording via the programmed key with the local function of
fragment recording and playback of voice messages on end-user devices;
−control of the ACM-IP2 analogue subsystem module with “Relay” function;
−free addressing of subscribers for versions with dial pad;
−connection to the IP network via ADSL or Ethernet 100BaseT;
−enabling organization of a group simplex call;
−call implementation on a priority basis (up to 255 priority levels);
−setting up unilateral control and “End” function modes;
−control (commutation) of external actuating devices using an integrated electro-
mechanical relay (lamp-type signaling device).
Configuration of the DW-IP2 shall be carried out using the personal computer of
the IPN network administrator on which IPN2 RU.RMLT.00041-01 IPN Config Tool software
configuration application is installed.

more 40 °C) with the following ranges of environmental parameters:
−operating temperature range: from −55 °Сto +55 °С;
−upper value of amber air humidity up to 100 % (at +25 °C with moisture
condensation);
−vibration frequency from 0,5 to 55 Hz with peak acceleration amplitude of
10 m/s2.
DW-IP2 ingress protection is IP66 as per GOST 14254-2015 (IEC 60529:2013).
The DW-IP2 satisfies requirements for electromagnetic interference resistance

1.1.4.5 Inside DW-IP2 enclosure (see Figure 5) is mounted the chassis (5), made of sheet
metal not less than 1 mm thick. On the chassis are installed threaded columns for fasten
CCS-DW-IP2 main board (3), threaded bushings for fasten a cooling radiator (is fastened
under the СCS-DW-IP2 board, not shown on Figure 5) иadditional amplifier 25 W (2).
NE01 board (4) or ADSL module (installed instead the NE01 board, not shown on
Figure 5) are mounted on the CCS-DW-IP2 main board by М2 threaded bushings. Also,
the cooling radiator is installed above the ADSL module through the M2 threaded bushings.
The standard 35 mm DIN rail (1) is fasten in the DW-IP2 enclosure by M4 screws
through the threaded bushings.
For easy connection DW-IP2, 10 pcs. terminal blocks (7) are fixed to DIN rail.
The terminal blocks are designed for connection of 28 to 12 AWG conductors (with the
external diameter of 0.321 to 2.053 mm and the cross-section area of 0.081 to 3.31 mm2).
Input and output electrical lines from DW-IP2 are connected via cable glands (6) −
1 pcs. for cable 6-13 mm dia and 2 pcs. for cable 6-13 mm dia.

Via the cable glands can be connected to the DW-IP2:
−Ethernet line with PoE function;
−additional Ethernet line;
−external power supply 48 VDC;
−ADSL line;
−an external loudspeaker (to the out of the amplifier 25 W);
−an external actuating devices (using pins of the integrated electro-mechanical
relay).
The handset in the appropriate versions (see Table 1) is connected via the kit for the
flexible metal tubing of the handset (see Figure 2, position 15), which is installed instead of
the cable gland for cable 8-17 mm dia..
Connection the mainboard with the DW-BC board is made by the special cable (see
Figure 5, position 8).
Spare cable glands are blanked with plugs (now shown at Figure 5).

Figure 5 – External appearance of the DW-IP2 enclosure (example)
(versions without handset, with additional Ethernet port and amplifier 25 W)
In DW-IP2 versions without amplifier 25 W (see Table 1) the CCS-DW-IP2 main
board can be connected to the PoE power supply source (injector) as a device
complying with the standard PoE IEEE 802.3af. In versions with amplifier 25 W the
CCS-DW-IP2 main board can be connected with the amplifier to one 48V power supply
source with proper power rating. If the CCS-DW-IP2 main board is powered from PoE
injector, amplifier 25 W shall be powered from a separate source.
