3.5 Detection Zone faults and Point faults
In standard AutroSafe, a point fault is presented as a detection zone
(DZ) fault; the point in fault can be accessed via the panel menu. Oil
and Gas panels can also be configured to present point faults as DZ
faults.
3.6 Fixed delay of Output (FPE) activation
AutroSafe can be configured such that extinguishing agent activation
is subject to a delay period; this activation delay time indicates the
period from when the activation criterion is fulfilled to when the actual
activation takes place (default delay: 10 seconds).
3.7 Support for Common Trouble Output
The Common Trouble Output can be connected to a BSB-310,
BN-310 or a BSJ-310 I/O module. The output is activated if any kind
of fault occurs in the Operation Zone to which it is connected. In
addition, any disablement or point inhibition within the Operation Zone
will cause the unit to be activated.
3.8 Support for Gas Detectors (4-20 mA input)
The AutroSafe Integrated Fire and Gas Detection System supports
the use of several gas detectors that are to be connected to the
PowerLoop via the PowerLoop 4-20mA Input Unit BN-342. These
include;
• Simrad GD10 IR
• Sieger Excel OPGD
• Sieger Excel Duct
• Draeger XP Tox
In addition, the interface includes a user-configurable type that may be
used to interface other types of third party gas detectors.
