INTRODUCTION
The Sur-Gard model SG-DV4420 is a combination of
Fire control panel and SCHED-3A communicator. This
fire transmitter consists of six channels: Two class-A
alarms A1 and A2, one End of line resistor supervisory
input S1, and three closed loop supervisory S2, S3 and
S4. There is also one programmable output, an AC fail,
and a low battery detector. The SG-DV4420 can transmit
up to ten codes to the MLR2 receiver at the central
station. It includes the 12V power supply/battery charger
and the 24V power supply for the F1/F2 modem. The
standby power is obtained from a 12V battery. The EEPROM programming is done easily and quickly
by using the SUR-GARD SG-DVT1 SCHED-3A tester. It
is only necessary to enter the account ID and options
needed. Other data such as the function bytes, delays,
etc. can be modified to meet different operating conditions.
