3.9 Support for Detectors Communicating on RS-485
(from SW 3.5.0)
Release 3.5.0 (and future versions) supports the use of different
detectors connected to the AutroFieldBus via the protocol-converter
unit BSD-321.
Supported detectors are:
AutroPath, open-path gas detector
SafeEye series 200/300, open-path gas detector
AutroFlame CCTV flame detector and video switch
Kidde Fenwal AnaLaser HSSD
3.10 Support for Extinguishing Control Unit
The Extinguishing Control Unit is a digital output device which is
connected to a BSD-310 or BSD-311 loop driver module via the
standard ALCOM loop. Because manual extinguishing medium
release activation will not be reported back to the system, it is
recommended that manual release activation switches are connected
to a Fire Alarm Interface Unit (BN-300) or connected to the manual
release activation switch to an output controlled by the extinguishing
unit activation.
Output activation criteria:
MFS (manual callpoint) within a defined group in alarm
Flame detector (camera) within a defined group in alarm
AutroOS (AutroCom) activation
Manual activation (activation of input A on unit)
Advanced output activation criteria:
Voted gas:
2 gas detectors within a defined group in alarm
1 gas detector within a group in Alarm and 1 gas detector within same
group in prealarm
Output activation result:
All General Outputs within a local defined output group is activated
Disable/Isolate/Override:
The Extinguishing Control Unit is a special case; it controls its own
disablement (override) state via a Field Isolate Switch, Switch
activation breaks the connection between the unit output and the
extinguishing agent solenoid (this is sensed by the unit output logic).
Activation of this switch wil disable the unit itself. In addition, activation
can disable other general outputs.
Activation of switch causes:
Disablement of actual extinguishing agent unit
All General Outputs within a local defined output group is disabled
