1. Introduction
1.1 About the Handbook
This document provides information on how to connect detectors and
other loop units to the Interactive Fire Detection Systems Autroprime
and AutroSafe.
Note that some loop units can be connected to AutroSafe only (the
indication “AutroSafe only” is written in the beginning of these
chapters).
For more detailed information on loop units, refer to the datasheet for
each specific unit.
1.2 The Reader

2.3 Connection of Branch-off
If necessary, a branch-off can be connected to a detection loop if the
existing cable layout requires this, but this is not recommended, as the
safety will be reduced.
To ensure a correct addressing of the detectors on a branch-off when
configuring the system, there can not be more than one branch-off per
detector. For safety reasons, the number of detectors on each branchoff must be kept to a minimum, as the detectors on a branch-off will
not operate in case of a break or shortcircuit on the branch-off. The
absolute maximum number of detectors on a branch-off (or an open
loop) is 32.

2.6 Detector Locking Mechanism
2.6.1 Detector Base
In the detector base a small locking nub will keep the springloaded
tongue in an open position to prevent the detector head from being
locked. If the locking nub is removed before mounting with a pair of
cutting nippers or similar, the detector head will enter a locked
position.
I
Detector base with locking nub
2.6.2 Detector head
The new springloaded tongue (figure 3) on the detector head will lock
the head in a correct position if the locking nub has been removed
before mounting.

2.6.3 Removing a locked detector head
• To remove a locked detector head, use a suitable tool
(for example a paper clip or similar) to push the
springloaded tongue in, and simply turn the detector
head counter-clockwise.
Use this hole to
access and release
the locking
mechanism.

2.7 Detector Dust Covers
Autronica detectors are supplied with a dust cover. To avoid possible
contamination of the detector chamber during installation, these
should remain in place on the detector until commissioning is started.
IMPORTANT:
LEAVE DETECTOR DUST

COMMISSIONING IS
STARTED

3.23 Remote Alarm Control Unit (BU-200)
Applies to AutroSafe only.
The Remote Alarm Control Unit is used for remote / local alarm
handling from predefined areas / zones. The main purpose of the unit
is to facilitate alarm handling without disturbance of people and
unnecessary calls to rescue services, for example, the fire brigade.
The unit can send acknowledgement and reset to the Control Panel
(BS-310/320/330). The Remote Alarm Unit is connected to the
detection loop. Each loop unit can be connected to one Operation
Zone. An Operation Zone can have one or more units, but requires
separate 24V DC power.
