Introduction
The DAX Digital Door Entry Telephone System is designed to provide security, by
means of Door Access Control, to all forms of communal housing including blocks of
flats, apartments, sheltered housing and nursing homes. The System is particularly
suited to medium and large sized buildings where a conventional Door Entrance
Panel, with individual push-buttons, may be impractical due to its size. The Entrance
Panel is designed for ease of use and with a very high level of Vandal Resistance.
The DAX system enables a Visitor to call an individual Resident from a Door
Entrance Panel; for the Resident to converse with the caller using a Telephone
Handset and, if required, to allow them access to the building by pushing a button to
operate an electric door release. The Door Entrance Panel has a simple 13-button
keypad for typing the flat number and a clear, large-character, LED display which
provides user-friendly messages and instructions.
Access to the building by Residents, Housing Officers, or other Authorised
Tradesmen can be achieved with the use of the Trades button. This can operate
either with a 4-digit access code or, if required, in conjunction with a Time-Clock for
unrestricted access during certain hours.
The DAX System operates on a >telephone exchange’ principle, as opposed to the
more usual >common wiring’ approach; Each telephone is isolated by an individual
relay circuit, fuse and cable. This ensures that conversations are totally private and
that any damage sustained to a telephone or its associated cable will not effect the
operation of the rest of the system.

Multi-entrance Operation
A DAX system may have up to four Entrance Panels. The operation from each of
these is exactly as described above, however, only one Resident, within a bank of
64 flats, may be called at a time. If a call is made from one Entrance, the other
Entrance(s) will display >WAIT=if an attempt is made to make a call from them.
On a system with more than one Control Cabinet (i.e. with more than 64 flats)
simultaneous calls are possible, providing both Entrances are calling telephones
within their local Control Cabinets; i.e. as soon as a call is made from an entrance of
one Control Cabinet to a telephone of another, all other Entrances/Telephones
within those two Control Cabinets will be engaged.

System Components
A DAX Digital Door Entry System comprises the following components:
•DPX Entrance Panels -one per door; each including a LM10 LCD Display
Module ( Liquid Crystal Display), and a Model 61 Speech Unit.
•DAX Control Cabinets -each complete with a Power Supply (with optional battery
standby), a Time-Clock, and all necessary control electronics to connect up to 2
entrances and 64 flats. Additional Control cabinets are needed for further flats
and/or entrances.
•Model 500X Telephones (or various other models) -one required per flat
•An Electric Lock Release -various types
DPX Door Entrance Panel
The DPX Door Entrance panel is of a flush-mounting, vandal resistant design. The panel
and surrounding bezel are laser cut from a single piece of 316 marine grade 2.5mm
stainless steel; this allows for a gap of only 0.2mm, rejecting tools that could be used to
force the panel from its back-box. The bezel is welded to an integral back-box made from
1.5mm 316 marine grade stainless steel.
The layout of the DPX panel is illustrated in Diagram 2 overleaf, which shows the following
features:-
•A large transparent window manufactured from LEXAN or an equivalent material
which has an extremely high impact resistance.
•A keypad comprising of 13 Vandal resistant Stainless Steel buttons.
•A speech grill comprising of a decorative pattern of closely-spaced 2.5mm holes.
•Clear Operating Instructions, laser engraved in black.

LM10 Display Module
The LM10 Display Module is an environmentally protected unit, manufactured with
Zinc Passivated steel to BS1449 and including a secondary protective window. The
Display module has a 4-character Dot Matrix LED Display and an 17mm character
height, giving excellent visibility in a variety of lighting conditions, including night-time.
Model 61 Speech Unit
The Model 61 Speech Unit, positioned behind the grill of the DPX Door Entrance
Panel, provides two-way speech communication between the door panel and
telephone. It has a plastic cone loudspeaker and Electret microphone, which provide
excellent weather resistance. Both amplifier circuits use a custom designed hybrid
circuit for high reliability. There are two controls at the rear for adjustment of speech
volume levels.
DAX Control Cabinet
All of the DAX control equipment is installed in one or more IP55, lockable, steel
cabinets.
The internal layout of the DAX Control Cabinets is illustrated in Diagram 3 overleaf
and contains one or more of the following components:
•CTX64P Door Controller PCB
•EXP64 Expander PCB
•RLX8 Relay PCBs
•TS2000 Time-Clock
•Model CAB5 Power Supply Unit.
•Optional Lead-Acid battery (6AH)
CTX64P Door Controller PCB
The Door Controller PCB provides all the necessary connections for interfacing to
one DPX Door Entrance Panel, as well as connections to the Electric Lock Release
and optional Fireman’s Switch, Sounder or Door Monitor Switch. One or two Door
Controller PCBs are fitted in each Control cabinet. If two are present, they will be
arranged in piggyback fashion, staggered to allow access to the connection
terminals. The bottom PCB always has the lower door address / number.
The upper PCB will reveal a slide switch (marked RUN-PROG) which is provided to
enable programming of various system parameters. (refer to >Programming the
Entrance Panels=).

EXP64 System Expander PCB
An EXP64 System Expander PCB is required when there is more than 64 flats or
more than two entrances per system. It provides the necessary interconnections to
additional DAX Control Cabinets. The Expander PCB is always positioned on top of
the CTX64P door controller PCBs (a Control Cabinet, provided purely for telephone
expansion, may have a single EXP64 PCB and no CTX64P door controllers).
RLX8 relay PCB
Each RLX8 Relay PCB provides connections to eight telephones. There will be a
maximum of eight RLX8 boards per cabinet allowing connection of up to 64
telephones. These will be clearly labelled 1 to (up to) 64. An LED is provided for each
telephone which illuminates whenever that telephone is called.
The RLX8 PCBs provide complete isolation between telephones by means of relays
and fuses. This ensures that any cable or equipment fault affecting one telephone
will not impair operation of any other telephone within the system. To maintain full
isolation a separate cable is required for each telephone. An alternative reduced
wiring system is possible whereby a single cable is used for each relay board thus
reducing the number of cables by a factor of eight; in this case isolation is maintained
between RLX8 boards, so that a single fault can affect only a group of eight
telephones.
TS2000 Time-Clock Module
The TS2000 Time-clock module is used to set time-periods when the >TRADES=
button is operative. It is programmable with up to 8 flexible on/off settings in a 24
hour or 7 day period. The TS2000 module has its own battery, allowing retention of
the program during power failure.
Normally there is only one TS2000 module supplied per system. However it is
possible to provide one TS2000 for each CTX64P Door Controller, should the time
requirements for each Entrance be different.

DPX-LED Isolating Exchange System PD059 Issue 2
13
CAB5 Power Supply
Each cabinet is separately power by an internal 12V DC Regulated Power Supply
Unit Model CAB5. Battery Standby operation is possible with an optional 6AH,
maintenance-free Lead-Acid battery. The PSU operates in >Floating Charge=mode
whereby the battery is connected directly across the power supply output. It has an
active short-circuit protection for mains operation and fast blow fuse protection for
battery operation.
An integral Two-Pole Mains Switch is provided to enable all other Cabinet
components to be isolated from the Mains Supply during servicing. This Illuminated
switch, together with red and green LED lamps, provide a clear indication of the
Power Supply, Mains and Battery Status.
Telephones
The following models of telephones are suitable for the DAX Digital Door Entry
System, having the facilities as indicated.

On a Fully Isolated System (see Cable Planning, Page 18), the use of Privacy
Telephones is unnecessary as >privacy of speech=is inherent, due to the line
isolation. Privacy telephones are recommended, however, when using the (partially
isolated) Reduced Wiring system, to avoid the problems arising from Telephones
being left off the hook.

DPX-LED Isolating Exchange System PD059 Issue 2

System Expansion
A Control Cabinet is limited to a maximum of 64 telephone connections and two
entrances. For larger systems additional Control Cabinets are required, each
provided up to a further 64 telephone connections and up to a further two entrances.
An expansion Cabinet may contain additional Relay boards (telephone connections)
only, or additional Door Controllers only, or a combination of both.
Custom Specifications for the DAX Control Cabinets
Number of flats per Control Cabinet
Each control Cabinet is fitted with a number of RLX8 Relay boards giving multiples of
8 telephone connections up to a maximum of 64. Unless otherwise specified, each
Cabinet will be filled with 8 Relay boards (64 flats) until the required number of flats is
achieved. Control Cabinets can be supplied with a lesser numbers of Relay Boards
to suit the layout of the building and the cables. However, as each control cabinet
must have its own Power Supply Unit and Expander PCB, this will be a more costly
option to the Customer.
Distribution of Door Controllers between Cabinets
Each Control Cabinet is fitted with 0, 1 or 2 Entrances (0 indicates an extension
cabinet for extra telephones only).
By default, Door Controller PCBs 1&2 will be placed in Cabinet 1, and Door
Controller PCBs 3 & 4 in Cabinet 2. In some cases the Customer may find advantage
in a non-standard configuration: For example, on a 2-Door 128-way system; by
placing Door Controller 1 in Cabinet 1, and Door Controller 2 in Cabinet 2,
simultaneous operation from both Entrances is possible providing that the call from
each Entrance is made to a telephone which is connected within the same Control
Cabinet as the Door Controller.
Time-clock Modules
Standard systems are supplied with one TS2000 Time-clock module in Cabinet 1. If
required, additional TS2000 modules can be supplied (up to 1 per Entrance) so that
each Entrance or group of Entrances can operate with different time settings when
using the Trades facility.

DPX-LED Isolating Exchange System PD059 Issue 2
15
Selection of Flat Numbers
For each telephone the Customer may specify any 1 to 4 digit number flat number.
E.g. 7, 101, 2018. The required numbering system is factory programmed and
therefore must be provided by the customer at the time of order. These numbers
maybe presented in an entirely random sequence so that the telephone connections
maybe conveniently allocated between relay boards and between cabinets to simplify
cable runs.
A printed form is available to assist in the presentation of the flat numbering scheme
by the Customer.
A document entitled >DAX Door Entry System Configuration Summary=is provided
with each Control Cabinet showing the pre-programmed flat numbers and their
corresponding telephone wiring locations.

Other System features
Lock Release
Each Door Controller PCB (CTX64P) provides two alternative pairs of connections for
Electric Lock Releases:
FAIL SECR: for devices that require power to release the lock and will secure the door in
the event of power failure. These are the most commonly used lock releases.
FAIL SAFE: for devices requiring continuos power to lock the door and release during
power failure, includes magnetic locks.
Both Outputs are rated at 12V DC at a maximum current consumption of 0.5A. For a
lock release or magnetic lock with higher rating or for AC operation, an additional Power
Supply will be required. In addition a relay must be used to interface with the CTX64P
Door Controller PCB. This is illustrated in diagram 8.
Egress button / Fireman’s Override switch.
Each CTX64P Door Controller PCB has a pair of connections marked EXIT which may be
wired to an external push-button for egress operation. Momentarily operating this button
will directly operate the lock release for the programmed duration.
Alternatively the input may be used with a Fireman’s Override Key-switch. Closure of this
switch will operate the lock release continuously; if this feature is used it is important
therefore that the lock release be of a continuously rated type.
A normally-open switch or push-button with isolated (i.e. voltage-free) contacts is required.
The Egress/ Fireman’s facility can operate the lock release for extended periods and
requires a continuously rated lock release.
Tone Output
This output operates, during lock release operation (except Egress / Fireman’s facility) or
when a telephone is called. This is normally used to alert the caller, with a DC sounder
placed in or near the door panel.
Two connections are required to the Door Controller PCB, marked >TONE=and rated
at 12V DC 100mA maximum. Positive connection is on the left.

DPX-LED Isolating Exchange System PD059 Issue 2
17
Door Open Indication.
This feature requires the use of Model 500LX, 500LXT, 500PLX or 500PLXT
Telephones. If a door is left open, this will be indicated on the green LED of the
Telephones. The LED may be programmed to be steady or flashing, and to operate
immediately, or after a delay.
On a multi-door system the Door Open Indication can be set to operate in either of
two conditions:-
i) Any Door within the entire system is open.
ii) Any Door connected to the same Control Cabinet as the Telephone is open.
Each CTX64P Door Controller PCB has a pair of connections labelled >DOOR SW=.
These connections must be wired to a magnetic door-switch or the contacts of a Lock
Release Monitor switch. Either normally-open or normally-closed switches may be
used.
