Edwards® B-8313 Series
Panel Mount Mechanical
Telecode® Relays
Features
Applications
Ordering Information
• Long-life tungsten contacts
• Gray finish
• High grade copper coils
For areas where ambient noise levels
are high or where personnel are unable to be near telephones at all
times such as factories, loading docks,
mines, quarries, lumber yards, gas
stations, foundries, etc.
Specify pull up coil resistance, voltage, and frequency data. For standard phone system ringing circuits,
specify same coil resistance as bell
ringer coils. For intercommunicating
phone ringing circuits, specify relays
of same voltage and frequency as
ringing circuit.
Description
The Edwards electro-mechanical,
panel mount, telecode relays are designed to activate up to 5 vibratingtype horns, buzzers, and bells. The
unit's windings are rated in ohms
rather than volts. Wire size and
number of turns vary with resistance
requirements.
The B-8313 series is not supplied with
a capacitor. If a capacitor is required,
order the Cat. No. B-8325 one micro
farad, 400V capacitor with bracket.

Relays operating on AC ringing voltage and used on common battery
circuits require capacitors. Relays operating on DC ringing voltages do not
require capacitors unless energized
by a common battery.
