GENERAL INFORMATION
1.1 SYSTEM OVERVIEW
he DIGI IZE Electronic ransmitter, Six Zone (DE -6B) is a solid-state
microprocessor coder for use over telegraph hard wire. he DE -6B is designed to
operate with a loop current from 50 mA to 750 mA. A dual 6-zone version (DE -12B) is
available in a larger enclosure.
1.2 DESCRIPTION
he DIGI IZE DE -6B is a elegraph ransmitter for Fire and Security Alarms. he
unit has six End of Line (EOL) resistor zones and includes a CAM lock, AC transformer,
standby battery and built-in charger. he unit is housed in a steel enclosure and is
suitable for mounting in convenient, out of the way locations on an interior wall. he
DE -6B can be used on the same loop with mechanical Fire Alarm Boxes.
elegraph codes unique to each of the six zones for rouble, Alarm and Secure as well as
Low Battery are transmitted over a 100 millampere circuit using PNIS (Positive Non-
Interfering Successive). he DE -6B has line current detection to avoid clashes between
more than one transmitting device. Automatic ground return, a Watch Dog imer, and a
jumper selected internal trouble buzzer assure continued main system operation and
operator notification in the event of a box failure. A built-in trouble relay output (Form
C), the ground and code relay (grounding, opening, or no effect on the 100 mA line) are
activated by the Watch Dog imer ensuring reliable failure detection.
ransmission speed is adjustable to match existing decoding units, as are the number of
digits for the box number and the last digit for alarm, trouble, and restore. Number of
rounds for each condition is also programmable.
Automatic switchover to battery power is performed upon AC power loss with a low
battery code transmitted if power is not returned in approximately 60 hours. After
transmitting a low battery code, the unit bypasses all input circuits to avoid spurious
transmission of false alarms.
