Well informed engineers and improved code requirements have increasingly adopted the logistics of implementing a cost effective means of maintaining proper system function. Ideal relations with, and retention of, your valued customer is the life-blood of all service based corporations that thrive on developing and maintaining various forms of Recurring Monthly Revenue (RMR) based on contractual agreements with their customers. Unfortunately, those revenue streams are at peril when there is system interruption of any kind.
Any wire / conductor that enters or leaves a building should be considered exposed to such factors as lightning and poor utility power. Wires / conductors that are contained within a building are most vulnerable to over voltage introduction from steel beam / girders, metal light fixtures, etc. Even as we enter into the world of wireless transmission, you still terminate copper at some point. There in lies inherent exposure.
These are common applications as to the ideal placement of E CLIPS’ fire and life safety products:
1) AC Power: Use one EC120H on every panel.
AC power note: By virtue of proper termination, all FACP’s allow for the introduction of a parallel TVSS connection. Parallel as opposed to a series function is recommended so as not to discontinue power to the FACP upon the EC120H having performed its function. (series devices are designed to discontinue power to the FACP, putting the system on battery mode) While designed to self-restore after an over voltage condition, any TVSS can “self sacrifice” to protect the equipment. In these events, the EC120H has been designed to “fail safe”, creating a ground fault, causing the FACP to apprise you of a “trouble” condition. Simply remove and replace the EC120H and reset the panel to resume normal condition and function. Remember that early notice to the TVSS of an over voltage condition is critical.
2) Dialers: Use two RJ31120-MDP on each panel for "the best protection" (hybrid, multi-stage components with tighter clamping levels).
Dialer note: For dialers / phone lines using screw terminal connection method to introduce TVSS please use model #T120-MDP for "the best protection" (hybrid, multi-stage components with tighter clamping levels).
3) 24v Circuits and Loops with > (more than) 150ma operating current: Use model #T24-MD for "the best protection" (hybrid, multi-stage components with tighter clamping levels).
Example: Notification Appliance Circuits (NAC), Power Limited Fire Alarm Circuits (PLFA) and Non-Power Limited Fire Alarm Circuits (NPLFA), power loops, horns, strobes, [DP] Smoke Detector power loops, smoke control system power, annunciator connections, etc. from manufacturers such as FCI/Gamewell, Notifier, Siemens, Simplex, Silent Knight, Firelite, Honeywell, ADT, Napco, and Ademco.
4) 24v Circuits and Loops with < (less than) 150ma operating current: Use model #T24-MDP for "the best protection" (hybrid, multi-stage components with tighter clamping levels).
Example: Initiating Device Circuits (IDC), Signaling Line Circuits (SLC), Smokes, Pulls, Heats, Addressable Monitor, and Control points, etc. from manufacturers such as FCI/Gamewell, Notifier, Siemens, Simplex, Silent Knight, Firelite, Honeywell, ADT, Napco, and Ademco.
Circuits and Loops note: E CLIPS products that have a suffix ending in "P" incorporate current limiting technology. It is best to incorporate over amperage restriction when possible, though some environments are not well suited for its use because of the minor resistance applied to conductors.
5) 5v data communication circuits (rs422, rs485): Use model #T05-MD for "the best protection" (hybrid, multi-stage components with tighter clamping levels).
