Edwards Signaling B-ERX-2100 User Manual

Installation Instructions for Catalog Numbers B-ER-1000,

B-ER-2000, B-ERW-2100, B-ERX-2100 Electronic Telephone Relays

DESCRIPTION

The Edwards electronic telephone relays are available in four
models: Modular Indoor (Cat. No. B-ER-1000), Hardwire In­door (Cat. No. B-ER-2000), Hardwire Weatherproof (Cat. No.
B-ERW-2100), Hardwire Explosion-Proof (Cat. No. B-ERX-

2100). The units are for use with horns, bells, strobes or similar
devices to create a remote signal extension that matches the tele­phone ringing cycle. The relays are activated by ordinary ring­ing voltage of the telephone.

• These devices are intended for connection to single line
telephone or key systems only. They are not intended for use
on "party line" or on coin telephone lines.

• When installed in accordance with these instructions, the
devices can be readily disconnected without affecting

equipment remaining on the telephone network.

• Registered with the Federal Communications Commission in
compliance with Part 68 of FCC Rules and Regulations.

• UL Listed.

IMPORTANT TELEPHONE INFORMATION

The following information may be required by the telephone com­pany: Telephone Number, FCC Registration Number: 3Z9USA­21250-RG-N.

The Ringer Equivalence Number (REN) allows the installer to
determine the number of devices that can be added to the tele­phone line and still have all the devices ring when the number is
called. In most but not all areas, the sum of all RENs for all
devices connected to your line should not exceed five. To be
sure of the number of devices you can connect to your telephone
line, contact your local telephone company.

If these devices damage the telephone network, the telephone
company will notify the owner that it may temporarily discon­nect service if they consider such action necessary. If the owner
considers the disconnection unwarranted, they have the right to
bring a complaint to the FCC.

The telephone company may make changes in its communica­tion facilities, equipment, operations, or procedures when such
action is required. If these changes render the devices incompat­ible with the telephone company facilities, the telephone com­pany will provide enough written notice so that necessary changes
can be made in order to maintain uninterrupted service.

INSTALLATION

NOTE: Telecommunication wiring which is connected to

either the B-ER-1000 or B-ER-2000 relay shall not
extend outside the building that the relay module is
contained in.

Modular Indoor Unit (Figure 1)
NOTE: This device is for indoor use only with telephones

having modular (RJ11C type) jacks.

1. Connect modular plug telephone line cord into modular jack
on bottom of electronic relay.

2. Insert power cord of signal device to receptacle on side of
electronic relay.

3. Plug unit into 120V, 60Hz wall outlet.

4. Connect signaling devices to 120V outlet on relay. Verify
operability of electronic relay.
