2. INSTALLATION
2.1 GENERAL
The FP2000 Series Analogue Addressable Fire Panels can address up to 128 Aritech
devices on a two-wire ring circuit (loop) using digital communication.
The following paragraphs will describe the connection and addressing of Aritech devices
in a fire protection system.
2.2 AUTOMATIC FIRE SENSORS
2.2.1 Where To Place Automatic Fire Sensors
SITING AND SPACING DETECTORS
Please consult local regulations and follow Fire Brigade requirements.
The following apply for flat, horizontal ceilings:
SMOKE
DETECTORS HEAT
DETECTORS
Max. area coverage 100m250m2
Max. horizontal distance between any point in
the area and the nearest detector 6m 5m
Max. ceiling height (general limits) 12m 6m
Note that these values change if:
•appliance is in small corridors
•there are obstructions
•appliance is in the apex of a pitched roof

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.
