Surge Protection
For Business-Critical ContinuityTM
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.

TER-043 (For 12 VDC, 24 VDC, 25 VAC Systems)
Installation
1. Install zone or loop circuit wires
(1 pair) at the vacant end of the
Edco TER. Torque terminal screws
to 3.5 LB-IN max.
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 LB-IN max.
CAUTION
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,
