2.2.2 Mounting Bases & Wiring Diagrams
All connectors on the base are numbered and have the following function:
1:(+) remote LED
2:(-) remote LED
5:(+) line in and out
6:(-) line in and out
Earth : to continue ground shield

2000 SERIES SENSORS INSTALLATION GUIDE Revision 3.1 June 1997
There are 4 different Mounting Bases available for the 2000 Series Sensors:
DB2001 :sensor base without remote LED connectors (Ø 10 cm)
DB2001U :sensor base without remote LED connectors (Ø 15 cm)
DB2002 :sensor base with remote LED connectors (Ø 10 cm)
DB2002U :sensor base with remote LED connectors (Ø 15 cm)
When sensors with remote LED drivers are being installed (for example DT2073,
DI2072, DP2071), the DB2002 or DB2002U should be used.
Please refer to Figure 1for Class A, and Figure 2for Class B (no return) wiring.
It is not necessary to observe polarity on terminals 5 and 6 as the fire monitors are not
polarity sensitive, but when the remote LED driver is being used, polarity must be
observed !
To install a detector head, insert the head and rotate it clockwise until it is properly
aligned and "sets" into the base (Figure 3). Then rotate it an additional 15º to lock it in
place.
Each 2000 Series Universal Mounting Base is equipped with a moulded locking
mechanism to prevent unauthorised removal of the sensor head (Figure 4). If you want
detectors to be locked into the base, remove tab before inserting into the base. To
remove the sensor head, insert a small screwdriver into the slot on the side of the base
and press in while simultaneously turning the sensor head counter clockwise (Figure 5).
The different Aritech Mounting Bases are designed so that the fire sensors will not
operate in the Isolator Mounting Base DB2003 and vice versa. The 2000 Series Range
of Fire Sensors will also not fit the base of another Aritech Range of Sensors.
A ground shield is strongly recommended, but not required. The shield must be
connected to the earth ground at one point only, preferably via an earth stud in the fire
control panel.
Address tags are available to write the address of the detector on. The address tag
should be positioned before the base is mounted.

2.2.3 Addressing
To install a detector address (see Figure 6), use a screw driver to adjust the two rotary
switches on the back of the sensor. Set the left rotary switch (0 through 12) for the 10's
and 100's digit and the right rotary switch for the 0 through 9 digit.

2.2.5 7-Segment Indication
The 207X models have a 7-segment display. The information displayed depends on the
panel the sensors are connected to.
When the 2000 Series Sensors are being installed with the Aritech FP2000 Fire Panel,
the following indications are available:
Figure 7: Indications on 7-Segment Display

2000 SERIES SENSORS INSTALLATION GUIDE Revision 3.1 June 1997
Notes: (Combined with FP2000)
•At the fire panel this information can be programmed to be always available (On) or
only when the sensor is being polled (Blinking).
•When the complete zone is disabled, nothing will appear on the 7-segment display of
the disabled devices.
•The maximum number of 7-segment displays active at the same moment can be
programmed at the panel (in ‘On’ mode).
•The test conditions mentioned above are tests initiated at the panel and not from the
sensor itself (see paragraph 2.2.6).
2.2.6 Diagnostics and Sensitivity Test Modes
Diagnostic and sensitivity test modes are available on the 2000 Series Detectors. The
2000 Series Smoke Detectors provide obscuration or temperature information to the Fire
Panel. Obscuration or temperature is determined by the number of counts received at
the Fire Panel when a 2000 Series Detector is polled.
The DP2071, DI2072 and DT2073 models have a seven segment display that allows
sensitivity, diagnostic and address data to be displayed at the detector head. Holding a
magnet near the integral reed switch (Figure 8) will initiate the diagnostic routine at the
Fire Panel.
Figure 8: Initiating the Diagnostic Routine
The following sequence will be displayed on the sensor :
First, the address of the sensor will be displayed (e.g. 35), followed by the real-time
value (e.g. 56), which is displayed twice.

2000 SERIES SENSORS INSTALLATION GUIDE Revision 3.1 June 1997
Figure 9: Sequences Displayed on 7-Segment Display
2.2.7 Testing, Maintenance and Cleaning
All 2000 Series Smoke Detectors are shipped with a plastic dust cover for use in areas
where construction is on-going. Smoke Detectors will not work with the dust cover in
place. Remove the dust cover when installation is completed, prior to testing.
All Smoke Detectors should be tested in place at least annually or according to local
regulations, to ensure smoke entry into the sensing chamber and alarm response. If
canned smoke (test aerosol) is used, carefully follow the manufacturer's directions to
avoid damage to the detector.
Test Heat Sensors by using a hot air gun (Figure 10A). Aim at heat sensor from 15 to
25cm away. Be careful not to melt the plastic.
The sensing chamber of the 2000 Series Photo-electric Detector unsnaps for easy field
cleaning and service (Figure 10B). Whenever the diagnostics indicates that cleaning is
necessary, remove the photoelectric detector cap, snap off and throw away the optical
block chamber (Figure 10C). Then blow off the optical block base and snap a new
optical block chamber back in place, replace the cap and verify sensitivity.
For 2000 Series Ionisation Detectors, remove the detector cover and clean the sensing
chamber and chamber screen whenever diagnostics indicate cleaning is necessary
(Figure 10D). Use a vacuum and/or filtered compressed air to remove dirt from the
chamber's interior. After cleaning, replace the chamber screen and detector cover and
verify sensitivity. If sensitivity remains out of limits, replace the sensor and return the
removed one to the manufacturer for cleaning and re-calibration.
Ionisation Sensors contain a radioactive source and should not be opened any further
than to clean as per above.

2.4 ISOLATOR IU2016
GENERAL
An isolator is a “device” which prevents a loop going down completely when a short circuit in
that loop occurs. When isolators are used, only the devices between two isolators will go down.
The IU2016 can be placed in the loop and is completely transparent for the protocol (in normal
condition). No address setting is required.
High-end fire panels, like FP2000, have built-in isolators per loop. This means that no isolators
have to be placed at the beginning and end of the loop.
INDICATORS
The yellow LED will start blinking when the isolator goes active i.e. when one side is isolated.
The short-circuit will always be located between two active isolators or between one active
isolator and the panel
INSTALLATION
The Isolator is fitted into the Isolator Mounting Base DB2003.
There are four single terminals, namely:
1. (+) IN : Line in
2. (+) OUT :Line out
3. (-) :Common negative
4. Single terminal :This terminal is intended as a through connection point for cable
shields or for an earth connection.

2000 SERIES SENSORS INSTALLATION GUIDE Revision 3.1 June 1997
Isolators are - unlike the other 2000 Series devices - polarity sensitive. The connection must be
as follows:
Figure 12 : Class A Loop with Isolator IU2016
Note :According to the EN54-directive, isolators should be placed at least every 32 devices.
The use of isolators per zone is recommended.
Please consult local regulations and follow Fire Brigade requirements.
