Dual-in-line switches
¨
Decide on the switch settings required for DIL switches S1 to S4. The switches
can be set for input, output or not used (off) position.
End-of-line units
¨
Connect the end-of-line (EOL) units to IO lines to allow fault free IO lines to
be seen during allocation of addresses.
Links
¨
Set as necessary the links LK1 and LK3 plus the rotary switch on the interface
board.
"
The mains terminals are located behind a metal cover inside the
interface unit enclosure.
¨
Connect the mains supply and power-up the unit, notice that LED1 (green) and
LED2 (yellow) are lit.
¨
Connect the battery and fit the battery restraint bracket.
Rotary switch
The rotary switch can be set to any one of its 16 positions, 0 to F.
¨
Normally the rotary switch is factory set for conventional SMS detectors
connected to interface input lines. Other settings are available to allow detectors
from other manufacturers.
"
All input circuits must have End-of-line units fitted, irrespective of
manufacture of detector.
On changing the rotary switch setting, the interface unit must be completely
powered-down, both mains and battery supply, and then powered-up again. Also
the loop on which the unit resides must be reallocated.
Other manufacturer's MCP
¨
Where an input circuit is required to have other manufacturers, manual call
points MCP, then a 3.9V zener diode should be fitted in series with the contacts
of the MCP. There should be no other components fitted to the MCP contacts.
"
Where NITTAN detectors and manual call point are installed on an input
circuit, the system will not be able to differentiate between a fire from a call point
or detector.
IO Line tests
¨
Test the IO line as per project specification. The tests should be based on the type of
equipment interfaced, for example the interface may control air-conditioning system,
escalator, fire door release or sprinkler system.
