Note
Input and output lines must be wired as a single radial circuit, without stubs or
T- junctions.
!
Warning
Disconnect all power supplies, (main and batteries) before connecting
or disconnecting wiring EOL devices or other devices to the control
panel.
Verify that the system operates normally (Idle) and that there are no
alarms prior to connecting or replacing extinguishing devices.
9.4
End of Line Resistors
For proper operation, End of Line (EOL) resistors must be connected to most I/O lines.
The value for the TSA-200 product family EOL resistor is 3.9K.
ALL THE INPUT AND OUTPUT LINES, USED OR UNUSED, MUST BE TERMINATED
PROPERLY.
i
Note
DO NOT CONNECT EOL RESISTORS TO RELAYS OUTPUTS AND 24V
OUTPUTS.
i
Note
Most extinguishing adapters have on-board EOL resistors, so no additional
EOL resistors are required. Verify EOL requirements for each specific
extinguishing adapter.
9.5
Removing and Installing EOL Resistors
Remove EOL resistors from the terminal block before connecting field wiring. After field
wiring is finished and all devices are connected, connect the End of Line resistors
(E.O.L.) to the last device of each Input or output which requires EOL termination.
9.6
Installation of Detectors and Manual Call Points
Install all detectors and manual call points (IF ALLOWED BY LOCAL REGULATIONS) at
their locations according to the applicable regulations.
i
Note
Manual Call Points act like Detector inputs
THEY ARE NOT MANUAL RELEASE (EXTINGUSHING TRIGGERING)
DEVICES.
