1 PURPOSE
The ADC-4001M Adapter is an addressable element that enables connection of a branch detection line
consisting of non-addressable devices to a loop-shaped addressable line of the POLON 4000 fire detection
and alarm system control panel.
The following non-addressable devices can be installed in a two-wire branch line:
-manual call points and 30 and 40 model range fire detectors, including the DOP-40 beam smoke
detector, as well as intrinsically safe fire detectors;
-fire detectors manufactured by other producers, equipped with non-potential NO contacts and an
alarm resistor, e.g. flame detectors manufactured by Det-Tronix;
-monitoring-alarming valves (equipped with non-potential NO contacts and an alarm resistor) of a
sprinkling systems, etc.
The elements that are installed in a branch line are assigned with a common address, determined by the
ADC-4001M adapter’s address and their activation evokes a fire alarm at the control panel. The adapter is
equipped with a short-circuit isolator.
The ADC-4001M adapter is intended for wall or ceiling mounting using the G-40 base.

4 DESIGN DESCRIPTION
The ADC-4001M adapter is placed in a casing similar to those of 40 model range detectors, however the
casing is not ribbed –the upper part is entirely closed. A cover is fitted to the casing and a two-colour diode
is located from the front side. The adapter is mounted in the G-40 installation base, where also installation
wires and cables screens are fixed to.

5 OPERATION DESCRIPTION
The ADC-4001M adapter is an addressable device operating in a loop-shaped detection line that monitors
two-stage detectors installed in its branch line. All line elements, installed in the branch line, possess a
common address determined by the adapter.
A fire signal induced by a detector installed in the branch line is transmitted via the adapter to the control
panel whereas it is signalled in the adapter with a red flashing diode light.
A branch line fault (short circuit or breakage) is also transmitted to the control panel; in this case the diode
flashes with a yellow light. Any branch line fault does not have any impact on the detection line.
The adapter is equipped with internal short-circuit isolator that cuts off the efficient part of the addressable
detection loop. The isolator, after revealing a voltage decrease on its contacts, resulted from a short circuit
in the detection line, cuts off the shorted section. The short-circuit separation is signalled with a yellow
diode flashings and appropriate information is passed to the control panel.
The adapter operates in six working modes. A proper mode shall be declared at the control panel. The
mode selection is provided in order to optimise the adapter current consumption adjusting it to particular
needs (see Table 1).

The entire current consumption by the adapter, regardless its state and the number of elements installed in
the branch line, is constant for a given operation mode.
Mode „1” - enables installation of up to 10 two-state detectors.
Mode „2” - the number of detectors installed in the branch line cannot exceed 20.
Mode „3” - enables installation of 1 - 2 two-state detectors.
Mode „4” - mode provided for interoperation with devices (e.g. monitoring-alarming valves of sprinkling
systems) that are equipped with non-potential NO contacts. An alarm is activated by connecting
to the branch line through an 8.2 kΩ resistor contact.
Mode „5” - mode intended exclusively for DOP-40 beam smoke detector connection (without an end-of-
line resistor –the detector jumper set in ADC-1 position).
Mode „6” - mode provided especially for interoperation with 40-model range detectors of low voltage
power supply. It enables installation of up to 5 40-model range detectors manufactured after
June 15th, 2002 (date stated in a warranty certificate).
Detailed information regarding designing rules of detection lines with ADC-4001M detectors installed in is
contained in the POLON 4000 system control panel manuals.
6 POLON 4000 INTRINSICALLY SAFE DETECTION LINES
The POLON 4000 intrinsically safe detection lines can be routed only as branch lines behind ADC-4001M
adapters using intrinsically safe separators manufactured by STAHL:
–one-channel type 9167/13-11-00s;
–two-channel type 9167/23-11-00s.
Maximum adapter branch line resistance shall not exceed 2 x 25 Ω (including both sections: before and
behind the separator).
The ADC-4001M adapter operation mode should be assorted suitably to a type and number of intrinsically
safe detectors or manual call points installed in an intrinsically safe line (see Table 2).

As an example, for currently manufactured TUN 38Ex, PUO-35Ex and DUR-40Ex detectors:
Mode „1” – enables installation behind an intrinsically safe separator:
–8 pcs. DUR-40Ex intrinsically safe smoke detectors, or
–4 pcs. TUN –38Ex intrinsically safe heat detectors (KDB certificate limitation), or
–1 pce. PUO-35Ex intrinsically safe flame detector (KDB certificate limitation).
Mode „2” - enables installation behind an intrinsically safe separator:
–10 pcs. DUR-40Ex intrinsically safe smoke detectors (system limitation).
Mode „3” - enables installation behind an intrinsically safe separator:
–1 pce. TUN –38Ex intrinsically safe heat detector, or
–1 pce. PUO-35Ex intrinsically safe flame detector, or
–1 pce. DUR-40Ex intrinsically safe smoke detector, or
–up to 10 pcs. intrinsically safe manual call points, equipped with a 1 kΩ alarm resistor (system
limitation).
NOTE: A branch line short circuit behind an intrinsically safe separator is signalled as a fire alarm. A line
short circuit between a separator and an adapter is signalled as a fault.
The separator should be installed in a safe zone, directly behind an endangered zone. An intrinsically safe
line behind a separator should be routed using an intrinsically safe unscreened cable.
In the case of intrinsically safe manual call points, the adapter should be declared as an immediate alarming
device (2nd stage alarm) and should be appropriately assigned in the control panel.
7 INSTALLATION
7.1 Installation place and fastening
The ADC-4001M adapter is designed for wall or ceiling mounting, inside premises, using the G-40 base.
The base should be fastened to a ceiling with two screws and expansion anchor bolts (Ø6 recommended). It
is advised to drill the bolt holes using a pattern of 63 mm hole spacing. Improper hole spacing may result in
the base deformation when the screws are strongly tightened. It may cause difficulties in inserting the
adapter into the base.

7 IK-E283-001E
7.2. Wire inserting
Wires should be introduced into the G-40 base through an opening in the back of the base. In case of
surface (on-plaster) wire routing, the base side wall should be cut off or narrowed with a file.
Notes:
1. No other elements can be installed in a branch adapter line that contains manual call points.
2. It is forbidden to use an alarm variant with cancellation for adapters that beam smoke detectors are
connected to.
3. It is forbidden to use an alarm variant with cancellation for adapters that manual call points are
connected to.
7.3 Wire connecting
The way of detection line connection is described in the G-40 base Installation and Maintenance Manual.
Fig. 2 shows how to connect a detection line and the ADC-4001M adapter. The adapter ‘positive’ power
supply can be connected to any clamp marked with ‘+’ sign. It is recommended to connect the adapter to
loop-shaped addressable lines but it can be installed also in a radial line or a loop-shaped branch line. The
branch line ‘positive’ wire should be connected to the base clamp marked with ‘WZ' sign. Screens of the
wires should be stranded and inserted into the additional connector (the connector should be squeezed
with fingers); then the connector should be placed between the guides in the base rectangular hollow.
8 SERVICING AND MAINTENANCE
The ADC-4001M adapter unfailing operation depends on ensuring proper operation conditions, appropriate
assembly execution and systematic periodical inspection. The periodical checks should be carried out at
least yearly by a person who knows the device operation principle and is able to reveal irregularities of its
functioning. The detector inspection consists in evoking an alarm in a branch adapter line and checking
whether an alarm signal is transmitted to the control panel.
Properly operating adapters, subjected to systematic periodical inspections do not require any other
maintenance works.
9 PACKING, TRANSPORTATION, STORAGE
The ADC-4001M adapters are packed into bulk packages. An installation and maintenance manual is
inserted into the bulk package.
The adaptors in factory packing should be carried out in closed spaces using usual land or marine transport
means. The devices should be secured from strong shakes and ambient temperature below –40 °C and
above +70 °C.
The ADC-4001M adapters should be stored in closed premises that are free of corrosive gases or vapours, at
ambient temperature from +5 °C to +40 °C and relative humidity between 40 % and 80 %, away from
heating devices. The storage period should not exceed 24 months.
