DC1664LC
Connect the LINKS PGMIn terminal to the PGM 9 terminal on the MEX2 module installed with the DC1664LC.
A 500 ohm resistor must be connected to GND between the PGM 9 and LINKS PGMIn terminals. Refer
to the Hook-Up Diagram in this manual.

LINKS RING Terminal Allows Panel to be Downloaded via LINKS
Whenever the LINKS phone number is called, the RING terminal will activate. This feature may be used to
make the control panel answer an incoming call via the cellular telephone network.
PC1500 and PC1550
Connect the LINKS RING terminal to the control panel’s Zone 6 terminal. When LINKS operation is enabled
in Programming Section [24], Zone 6 will be automatically configured for LINKS operation.
If the control panel is programmed for End-of-Line Resistor zones (see Section [12] Zone Light 5), connect a
1000
Ω
resistor between the LINKS1000 RING terminal and the control panel Zone 6 terminal. If the control
panel is programmed for normally-closed zones, do not connect a resistor between these terminals.
PC1575 and PC1580
PGM2 configured for LINKS Answer allows downloading to be performed in the event of phone line failure.
When the LINKS receives a phone call, it will activate the RING terminal on the LINKS circuit board. The PGM2
programmed as LINKS answer always requires a 2200 ohm resistor. The LINKS answer zone must be wired
with a RM-1 relay as shown in the hook-up diagram.
PC2550 and PC3000
Connect the LINKS RING terminal to the control panel’s AUX input to provide a forced answer for downloading
purposes. Refer to the “Programming” section of this manual for information on programming the PC2550 and
PC3000 control panels to enable the “forced answer” option.
PC2525
Connect the LINKS RING terminal to an available zone terminal on the control panel. Refer to the
“Programming” section of this manual for information on programming the zone for the “LINKS Answer” option.
If the PC2525 is programmed for End-of-Line Resistor zones (see Section [8] Zone Light 1), connect a 5.6K
ohm
resistor between the LINKS1000 RING terminal and the PC2525 zone terminal programmed as “Forced Answer”.
If the PC2525 is programmed for normally-closed zones, do not connect a resistor between these terminals.
PC5010, PC5015, PC1555, PC1565, PC5008, PC580, PC585, PC4010, PC4020, PC4020KT, P16LC,
P1664 and DC1664LC
Connect the LINKS RING terminal to an available zone terminal on the control panel. Refer to the “Programming”
section of this manual for information on programming the zone for the “LINKS Answer” option.
