You Using I/O Effectively
addressable fire systems are becoming increasingly
I/O intensive as more functionality is incorporated
into fire detection systems.
manufacturers generally have a good range of
"I/O" modules available, however the
number of inputs and outputs is sometimes limited
with I/O intensive applications requiring several
large and expensive modules mounted or installed
at a single location. Syncro "I/O"
offers a cost effective solution.
Kentec Syncro system was conceived with the
growing need for I/O in mind and can provide
an additional 512 channels of network wide,
configurable I/O on each individual control
panel via an onboard RS485 bus.
A range of modules are available to suit different
applications can be mounted locally or up to
1200 metres away as follows:
channel I/O board – S560
16 channels each of which can be configured
as an opto isolated input or an open collector
outputs. Ideal for driving LED mimic panels
or conditioning switch inputs.
way relay board – S547
8 volt free changeover relay contacts each rated
at 1 Amp 30 V DC.
way sounder board – S546
6 voltage reversing sounder outputs fused at
0.5A. 2 volt free changeover relay contacts
rated at 1 Amp 30 V DC. 2 opto isolated inputs.
way detection zone board – S545
4 monitored conventional detection zones, 2
voltage reversing sounder outputs rated at 0.5
Amps, 1 fire volt free contact rated at 1 Amp
30 V DC, 1 fault volt free contact 1 Amp 30
– Multi Input/Output board - S559
For Hochiki systems requiring multiple inputs
and outputs from the loop the S559 MIOU unit
provides 8 opto isolated inputs and 8 volt free
changeover relay contacts rated at 1 Amp 30
V DC at a single address.
The next time you need to specify I/O on a system,
remember there is an alternative to the costly
and bulky modules you would normally use and
