Emerson Edco TER Installation Manual

Edco TER Series

Single Pair Medium Duty Low Voltage Zone/Horn/Strobe/Data

The Edco TER surge suppressor directly installs onto electronic circuit wiring
terminal screws. This close proximity preserves Edco TER’s response time, clamping
level and ground reference by eliminating lead lengths. The Edco TER’s miniature
size fits directly inside fire or security panels, CCTV housings and other system
electronic enclosures. These features maximize surge suppression performance
while reducing hardware and labor costs to install.

2. Slip the Edco TER’s Rigid Mounting Prongs into
the panels designated Zone or Loop terminals and
tighten.

3. Using a 16-12 AWG solid wire, attach all Edco TERs
via the center ground terminal. Run this wire to
your panel’s “single point” AC power ground or
building approved ground. Torque terminal screws
to 6.0 in. lbs. max.

Note:

A. Never install data wiring during a lightning storm.
B. Disconnect data line before installing the protection

module.

C. These protectors are intended for indoor use on

communication loop circuits which have been
isolated from the Public Switch Telephone Network.

D. The communication loop circuits shall not be

exposed to accidental contact with the electric
light or power conductors. The protectors shall be
installed per the applicable requirements of the
National Electric Code, ANSI/NFPA 70.
