If the transmitter is not communicating (no signal on Rx
led of transmitter) to the central station at this point, call
the telephone Company and ask them to make sure
that the “Leg” is on. The telephone company will ask
you for the circuit number and the leg number which
can be found along with the service telephone number
on a card fixed on the F1/F2 subset.
REQUIREMENTS FOR ULC
INSTALLATION APPROVAL
• All components used in the system (contacts, detectors,
etc...) must be ULC listed.
• Wire the transformer to the A.C. line according to the
electrical code on a separate circuit breaker.
• The F1/F2 subset should be placed in a metal box,
(for example the SUR-GARD SG-UMBX1) close to
the control panel.
• The battery must have a minimum ampere hour
capacity of 6.5AH. In case of long time power failure,
the control panel must function normally for 24hrs.
NOTE: Refer to ULC Standard booklet “FIRE ALARM
CERTIFICATE SERVICE OF UNDEWRITER’S
LABORATORIES OF CANADA”. You can
contact ULC at Toronto for more information
or to obtain the booklet.
CONTROL POINT INFORMATION
Control point #1: programmable output PGM OUT
The control point #1 can be activated remotely from the
receiver. This is done by sending a command containing
the subscriber unit ID, which identifies to which unit the
command message is addressed and the point ID which
identifies the control point.
Point ID bytes are split into 2 digits. The first digit specifies
the type of command and the second digit indicates
which control point is to execute the command (on the
DV4420, the control point is always #1). The point ID
byte start with a letter from A to D, giving the desired
output function, as follows:
A. Turn On the specified point.
B. Turn Off the specified point (stop).
C. Turn On for 2 seconds (Pulse) the specified point.
D. Flash the specified point, 2 seconds On, 2 Seconds
Off, until a command is received to stop (B).
When a new command is received, for the programmable
output (control point #1), it replaces the command
previously in effect, if any.
Control point #1 can be activated internally (locally) by
the unit, for an “on time” of 2 seconds, when the SG-
DV4420 receives the “Kiss OFF” character from the
receiver. The “Kiss Off” character is sent by the receiver
as a confirmation signal that the last change of status
message from the SG-DV4420 was correctly received.
This output command takes priority over any command
that output point was already executing.
A. For 50 feet to 100 feet
• Use #18 awg shielded 4 conductor cable such
as Provo (Cat. Num. 1782-21) or Belden (Cat.
Num. 9814).
• #22 or #24 awg shielded 4 conductor cable.
B. For 100 feet to 500 feet
Use Low Capacitance #24 awg shielded 4 conductor
cable such as ALCATEL (Cat. Num. 371-02-24), Provo
(Cat. Num. 6652-21), or Belden (Cat. Num. 9927) for
the RS-232 communication (Rx, Tx, and SG).
You must also use a 24Vdc power supply (such as
Sur-Gard's SG-2415 24Vdc power supply) close to
the F1/F2 Subset to power it. Make sure to run a
wire (#18 or two #24 awg wires in parallel) between
the negative 24Vdc terminal of the Fire Transmitter
and the power supply, so that they are connected
together.
POWER-UP PROCEDURE
Before applying power to the SG-DV4420 or the F1/F2
subset, connect the 24V output to the “Batt” input of the
F1/F2 subset.
Connect the tansformer, wait approx. 5 seconds. Check
that A1 and A2 loop status led lights are off and the
green “A.C. POWER” led is on. If a led(s) does not turn
off, find the cause (such as loop open or shorted) and
correct it. If the “A.C. POWER LED” is off, find the cause
(such as breaker turned off) and correct it.
NOTE: To supply AC power to the SG-DV4420, the
transformer should not be connected to an
outlet that is controlled by a switch.
Check for the WATCH-DOG led pulses. This led indicator
flashes once every 10 seconds to show unit is functioning
normally. Activate a zone to be sure that the panel is
responding to signals. If the panel does not respond
and there are no indicators on, check that the wiring is
correct. If the panel is responding normally, connect the
battery. The red battery lead attaches to the positive
battery post and the black battery lead attaches to the
negative battery post.
SYSTEM TESTING
First test the system thoroughly using an SG-DVT1 tester.
Contact the monitoring station to request a transmission
test before connecting the 6 pin modular cable to the
modem. Trip an alarm on any loop. Wait for the
communication to complete and check with the monitoring
station to confirm the transmission. You can use the Rx/
Tx Led indicator to see if the transmitter receives or
transmits. Perform additional transmissions required by
the monitoring station.
The system should be tested on batteries only and AC
only, to be sure that both supplies are present and
adequate. Make sure that the AC Power to the unit is
connected to a separate, well marked, circuit breaker
which will not be turned off by accident.
