SOFTWARE SPECIAL FEATURES
EASE OF PROGRAMMING
The system ID code and other programmable parameters
will be downloaded into the module EEPROM by using
the SG-DVT1 Tester (with program version 5.0 or later)
as an access terminal. The SG-DVT1 is plugged into
the SCHED-3A line modular socket.
SELECTION OF TRANSMISSION
It is possible to select, for each zone, no transmission,
alarm transmission only or alarm and restore transmissions.
ACTIVATION AND RESTORE DELAYS
The loop A1, Low Battery detect and the AC fail detect
have programmable activation and restore delays to
reduce false alarms and nuisance troubles.
BELL OUTPUT FUNCTION ON PROG. OUTPUT #1
The PGM OUT can be activated by alarm on A1 only,
A2 only or both. It has a 17 minute autoreset.
LINE TROUBLE WARNING
If the transmission line were cut; the unit would give a
2 seconds pulse to the PGM OUT output after a
programmable delay of 60 sec. or 120 sec.
The A1/A2 Class A Fire/Sprinkler circuits must have
one closed loop between its two + terminals and another
between its two - terminals. Opening one of those loops
will cause a fire trouble and shorting across the loops will
cause a fire alarm.
SUPERVISORY INPUTS:“S1”,“S2”,“S3”,& “S4”
There are four supervisory circuits provided, which may
be used to monitor other parameters such as main
valve and\or pressure. The first supervisory loop, S1, is
an End of Line Resistor loop. The supervisory loop S1
must have a 2.7K end of line resistor.This is not a Class
B fire circuit, since either a short or an open circuit
condition causes the same supervisory signal.The
supervisory loops S2, S3 and S4, are used for normally
closed switch contacts.
PROGRAMMABLE OUTPUT: "PGM OUT"
The SG-DV4420 has one programmable output, switching
to negative, with a 150 ohm 1W current limiting resistor.
A sensitive relay (with a coil resistance of 700 ohms or
more), a buzzer, a LED or compatible DC operated
device may be connected between the AUX (positive)
terminal and the PGM OUT (switched negative) terminal
on the main board. Typical uses are: control relay, alarm
on A1 and/or A2 indicator, line trouble warning indicator,
or “Ring Back” (call received confirmation).
The operation of the Programmable Output depends
upon which option is selected in the programming table.
See the Programming Guide for a list of programmable
operation possibilities programmed at Location 27. The
programmable output can also be controlled remotely
from the receiver.
SELECTION JUMPERS
The program selection jumper must be left open.
ON BOARD LED INDICATORS (SEE FIG. #1)
WATCH-DOG: Flashes once every 10 seconds to show
unit is functioning normally. Any other flashing period
indicates a malfunction in the unit.
TX LINE: Flashes when unit transmits data.
RX LINE: Flashes following incoming data.
A1 FIRE/TROUBLE: Light ON when zone A1 in alarm
or in trouble.
A2 FIRE/TROUBLE: Light ON when zone A2 in alarm
or in trouble.
