Output 1 may be used to trigger an optional 675 Ground Start module for
installations having telephone lines which require ground start instead of loop
start operation to obtain dial tone from the telecom central office.
When the control has a message to transmit to the central station, it will seize
the line, go off hook, and then trigger the 675 module to connect the "RING" side
of the telephone line to earth ground. The panel will cause the module to break
the connection between "RING" and earth ground when it obtains a dial tone.
1. Connect the 675 Ground Start Module to the panel's J7 connector trigger
output 1, to auxiliary power, and to the "RING" side of the telephone line as
shown in the diagram below.
2. Use the following procedure to determine which side of the telephone line is
the "RING" side:
a. Connect the "+" lead of a DC voltmeter to earth ground, and the "-" lead
to one side of the telephone line.
b. The wire which reads +50VDC is the "RING" side.
3. Programme field 1*46 must be set to 0.

Output 1 may alternately be programmed to change states when the system is
armed in the away mode and then disarmed. If field 1*46 is set to 1, the output
will be set high when the system is in the "disarmed" state, and will switch to "0"
volts when the system is armed in the "away" mode. This trigger will not change
state unless all partitions are armed, and will change state again as soon as one
partition is disarmed.
Output 1 may alternately be programmed for a remote keypad sounder. You may
use an Ademco PAL 328N piezoelectric sounder for installations where you want
the sounds produced by the keypad's built-in piezo sounder to be duplicated in
another location for one partition. The panel will send all sounds remotely (i.e.
alarm, trouble, chime, entry/exit, etc.) except for the short clicks associated with
keypad key depression.
One application of this feature might be to produce chime sounds in a location
which is distant from the panel's keypads. You can also accomplish this by using
relay outputs (see RELAY OUTPUTS AND POWERLINE CARRIER DEVICES
section).
• Connect the Ademco piezo between the panel's auxiliary power and the J7
connector trigger output as shown in the Remote Keypad Sounding
Connections diagram.
