Power Terminals + 12v –
NOTE: Do not apply power to the unit until all wiring connec-
tions are completed and the antenna is attached to the unit.
Connect the power terminals (+ 12V –) to the BELL+ and
COM terminals or to a separate 11.5-14Vdc, 1A power
supply. If you will be using a local bell or siren, use a
separate power supply for the LINKS2150. Do not connect
the LINKS2150 to the Keybus RED terminal.
NOTE: The current drawn by the LINKS2450 and the siren(s)
connected to the Bell terminals must not exceed that specified
by the rating of the control panel. Refer to your control panel's
Intallation Manual for more information.
The wiring between the LINKS2150 and the power supply
should not be longer than indicated in the table below:
Wire Gauge
AWG
22
20
18
You can double the maximum wire length if you double the
conductors and connect them in parallel. Mount the
LINKS2150 as close to the power supply as possible.
TRBL Trouble Terminals
AC TRBL Input Terminal
The AC TRBL input terminal is used to report AC failure
troubles. If the power supply being used has an AC failure
trouble output, connect the output to the AC TRBL terminal.
When the AC TRBL terminal is shorted to ground, the
LINKS2150 will transmit the External AC Trouble reporting
code programmed in Section [10].
LB TRBL Input Terminal
The LB TRBL input terminal is to report low back-up battery
trouble. If the power supply being used has a low battery
trouble output, connect the output to the LB TRBL terminal.
When the LB TRBL terminal is shorted to ground, the
LINKS2150 will transmit the External Low Battery Trouble
reporting code programmed in Section [10].
OUT TRBL Output Terminal
The OUT TRBL output terminal will switch to ground when
the LINKS2150 detects a trouble condition. The OUT TRBL
terminal may be connected to a control panel zone
terminal to report LINKS2150 trouble conditions to the
security system, or the OUT TRBL terminal may be used to
activate a visual or audible trouble indicator.
This output may be used to activate a trouble indicator,
such as an LED indicator, a low current sounder, or an RM-
1 relay connected to another device.
YEL and PGM PANEL Terminals
The YEL PANEL terminal is used to connect the keybus
yellow from the PANEL.
The PGM PANEL terminal is used as a tamper to clear
tamper faults. This terminal must be shorted to the COM
terminal.

When using the LINKS2150 with a security system,
connect the COM terminal to the negative DC power
supply terminal of the security system control panel.
YEL and GRN KEYPAD Terminal
The GRN KEYPAD terminal is used to connect the keybus
green from the PANEL.
The YEL KEYPAD terminal is not used.
MOD OUT and V SUP Terminals
These terminals connect the LINKS2150 to the radio
transmitter. These connections are made at the factory
and should not be altered.
