End of line resistors eols are very important for circuit and loop supervision. How to use eol wiring in alarm systems grades in alarm systems.
Spider Resistor Packs
Eol wiring diagram. There are however occasions when we may need to configure zones to operate without eol supervision. Eol is the end of line resistor wiring in burglar alarm installation. Alarm systems are now categorized in different grades considering the risk or threat protected and the equipments in it to do sogenerally there are four grades named numerically from 1 to 4 with increasing risk factors. It is always good practice to use end of line resistors eols in any type of security circuit. Once theres a raging fire its a little bit late to troubleshoot and fix the wiring issue. When you wire an alarm system whether it is addressable or conventional all wired devices as well as the loop or the conductors used in wiring must be supervised for operation and connectivity by the main panel through the eolthere are two ways to wire eols.
The circuit needs to be completed to pass the continuity testing electricity through all the wires of the class a or class b circuit. In past it was common to wire a sensor with double pole technique. How to wire security alarm zones. On the flip side there are cases where extra protection is desired. Then again if between the control panel and the fire. When a sensor is wired with control panel end of line resistors are used in order to monitor alarm and tamper circuits.
An eol or end of line resistor is used to complete a circuit.
