Loading factor
line devices have an individual loading factor
(depending on device type see page 32)
Detector with external alarm indicator (AI)
− max. 2 AI3xx admissible per detector (device)
− max. output current 15mA
− flash interval: active phase 32ms / inactive phase 1sec
Line type
− 1 loop + 1 stub line or 2/4 loops or 2/4 stub lines
− programmable via user functions
Communication principle
sensor / actor-bus
− Cerberus protocol ’K1131’, serial communication
− typical 14 bit (2 priority / 8 address-bits / 4... data-bits)
− start-up addressing mode as ’daisy-chain’
Polling principle
cyclical polling with alarm interrupt (alarm interrupt only MT3xx / ABI32xA)
Polling sequence
during state ’quiescent’:
response upon alarm:
polling of 1 device per 0,5 sec.
(with 128 devices = each device is polled every 64 sec.)
within 2 sec. (by means of ’alarm interrupt’)
Information from detector to FC330A
state ’quiescent’
’call point alarm’
’alarm-HS’ (increased sensitivity)
’alarm-LS’ (normal sensitivity)
’fault’
’drift’
Information from FC330A to detector
− activation ’alarm indicator’ inside detector, call point, etc.
− activation output contact AB.../ABI... or control line on CB320A
Allocation line device
logical ZONE
special feature:
according to ’order of installation’
Default allocation:
device 1 line 1
ZONE 1
device 1 line 2
ZONE 129 etc.
Line break detection
detected by missing device(s) in mode ’stub line’ or
detected by EOL circuit (inside FC330A) in mode ’loop-line’
Loop supervision
detected by missing device(s) or by periodical supervising session
of the return line (sequence every 55 sec)
Line short circuit detection
− short circuit (
130
) initiates a ’line start-up’ in order to locate and
isolate the faulty section within the line
− short circuit (130....1000
) initiates the isolation of the faulty section
within the line
− each device has a built in line separator
Installation
line cable type:
line resistance:
line capacitance:
− twin wire, twisted, non-shielded
(use of existing untwisted cable is admissible)
− max. 150
− max. 300nF
Line specification
− voltage during ’polling phase’:
10V
− voltage during ’charging phase’: 24V
− max. current (limited):
100mA
Device specification
− max. current consumption (quiescent): 200
A (310
A control unit side)
− internal resistance ’during start-up’:
− designed as sensor/actor (non-latching)
