# AlarmTER Series
Polling Loop/Initiating Circuit

The TER surge suppressor installs directly onto electronic circuit wiring terminal screws. This close proximity preserves TER's response time, clamping level and ground reference by eliminating lead lengths. The 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 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 TERs via the center ground terminal. Run this wire to your panel's "SINGLE POINT" AC power ground, or Building Approved Ground.
