1. Introduction
1.1 About this manual
This manual describes the installation of a smoke detector system
based on Autronica’s AutroSense 75 aspirating detector. The manual
also contains guidelines for the installation of exhaust pipes,
procedures for commissioning the system, and a brief description of
service and maintenance functions.
1.2 The product
The AutroSense 75 aspirating detector comes in 3 different versions:
• BW-75/ADR for an addressable analogue system
• BW-75/ADS for an addressable analogue system with heightened
sensitivity
• BW-75/KON for a conventional system
1.3 Application
AutroSense 75 is designed for use in all situations, including corrosive
and dusty environments. The detector can be adapted to suit the
prevailing conditions and provide the required detection level by
using detector chambers with different levels of sensitivity.
The detector can be connected to either one or two exhaust pipes.
Where the AutroSense 75 is connected to an analogue addressable
fire alarm system, each individual pipe will be allocated its own
address. In the event of an alarm being reported, the area monitored
by the respective pipe will be identified on the fire alarm control
panel.
In a conventional system both chambers will be normally connected to
the same detector loop, i.e. both pipes will monitor the same detection
zone. It is possible to connect two different detector loops to the
detector chambers to obtain information about which pipe is in alarm.
1.4 The reader
This manual is designed for use by authorised service technicians and
others responsible for the installation.

2.3 Positioning of the detector
If the pipes are to be installed in rooms with different pressures, the
detector should be located in the room with the lowest pressure.
In a building where the ventilation system causes a substantial
negative pressure, the detector should be located in the room in which
the pipe system is installed.
In instances where the detector has to be located in the room with the
highest pressure, a return pipe must be attached to the lower pipe
outlet and fed into the room with the lowest pressure. This means that
the return air will be led into the room with the lowest pressure.
2.4 Mounting the detector
The unit is fitted with 4 fixing holes:
• Mark off and drill holes for 6 mm (max.) screws (and plugs if
necessary).
• Remove the cover (the illustration shows the detector without its
cover).
• Tighten all 4 screws .

2.5 Cable entry
The power supply and loop cables are fed in through the underside of
the unit via threaded glands (2 such glands are provided).
The unit is also supplied with 2 lead-in holes fitted with plugs. These
can be removed as required.

2.6 Cable connections
2.6.1 Introduction
This chapter covers all necessary external cable connections.
IMPORTANT:
The following procedure refers to primary installation:
1. Carry out all necessary loop connections.
2. Do not connect up the power before commissioning, see Chap. 4.5.

2.6.3 Terminal strips 1 and 2
IMPORTANT! Terminal strip 1 is for all external connections, i.e.
detector loops and power.
Terminal strip 2 is for internal connections only. These connections
have already been implemented, except that with the external
connection of 1 detector loop (conventional version), endload 1
should be removed (terminal strip 2).
For further details about internal connections to terminal strip 2, see
Appendix.
