END OF LINE RELAY COIL Resistor Figure 5.

. Jul 14 2010. If the electricity stops flowing a trouble is displayed on the panel. The circuit needs to be completed to pass the continuity-testing electricity through all the wires of the Class A or Class B circuit.

The EOL-CR Universal End-of-Line Device Mounting Plates are used when required to place the end-of-line device at an accessible height. Typical 4 wire system wiring Figure 6. Our company is dedicated to help and supply your fire equipment needs with the best prices Worldwide.

Ohm End Of Line Resistors 47K 10 pack Main Features Limited Warranty. It goes at the end at the device. Although there may be practical reasons for doing this it must be understood that placing resistors anywhere other than the end of.

Last edited by a moderator. 1x 4k7 1x 2k2 6k9. There have been many discussions about placing the resistors at the control panel in the can as the professionals say.

You just need a circuit that senses that current and triggers if. Jan 23 2017. End-of-line devices for electrical supervision shall be located in a separate enclosure installed less than 1800 mm above finished floor level measured from the centre of the end-of-line device.

The resistor limits the current to a bare minimum so the panel doesnt think its detecting a fire but at the same time it allows the panel to confirm that current is flowing through all the wires. Thats where the end-of-line resistor comes in. The voltage level of this transition is V2 When the EM field arrives at the end of the transmission line two nanoseconds later it encounters an open circuit and is reflected back down the line.

Zone Shorted - Alarm - All current bypasses the end of line resistor. Power supply may be required. So I asked this on Facebook.

The ones that are normally held closed like most door and window contacts are in a series string with the end of line resistor included in that string to keep the zone from having a Zone. The majority of respondents were adamant that the resistor goes at the contact hence EOLR End Of Line Resistor. Termination of EOL End of Line Devices Smoke Alarms waross Electrical 12 Jan 12 1734 In Canada EOLs are often mounted on a switch cover plate and installed in a switch box at the same height as pull stations.

End of line resistors for those systems are installed here. Fire and gas alarms burglar alarms and emergency shutdown systems all respond to the emergency at hand on a pre-established condition. Ad Precision Surge Current Wide Terminal High Voltage Thin Thick Film High Temperature.

Tinned Resistor Attachment Resistor leads are crimped to wires. So for a Scantronic Panel with ten contacts on one zone this would be. The end of line resistors EOLR for short are resistors designed for a pre-determined valued and used to control protected zones.

Quality 1st award winning customer service. End of Line Resistance Module Item Specifications Dimensions H 231 cm 091 in. Well reference the definitive answer in CANULC-S524-06 Canadian Installation Standard for Fire Alarm Systems Section 513 End-of-Line Devices Sentence 5131 reads.

The end of line resistor limits this current to prevent a shorted zone condition. And so what this will effectively do is make the end of line resistor be in the can but still function as a end of line resistor. Simplex 4081-9008 End of Line EOL Fire Alarm Resistors 1 Supplier for Fire Safety Equipment in North America.

Widest Range of Sizes Resistances. The way alarm systems do this is by analyzing the electrical system. Comforts End of Line Resistor values are 27K ohms in series with the contact and 47 K ohms in parallel with the contact.

Your alarm panel will be in fault and constantly bleep the value you should have is 68k but this depends on the make of panel you may require a minimu the EOLs are normally inside the alarm in a plastic bag when you buy the alarm. It turned into quite the flamewar. So heres our single end of line resistor circuit.

Typical 4081 Series Resistor Harness Assembly full size except for lead length Specifications Overall Length Approximately 9-12 241 mm Wire Length 7 178 mm 1 25 mm Wire Size 18 AWG 082 mm2 Insulation 600 V black Leads Stripped 05 13 mm. Simply remove a half-inch of the white wires insulation attach one leg of the resistor to the white wire and tighten them snugly with a wire nut. And so well go ahead and go to the table now and Ill show the example of it.

Then insert the other leg under the terminal screw. The 27K ohms value can be substituted with 22 Kohms without any problem. It fits on a standard single-gang electrical box.

The EOL-CR consists of a terminal strip mounted on a heavy gauge metallic single gang faceplate finished in red or white baked enamel. 4-wire system with full monitoring Fire detection systems 8806 1146 Page 7. In this case if the device is connected to a fire control panel able to distinguish between different.

An EOL or End of Line Resistor is used to complete a circuit. The values 22 Kohm and 47Kohm are commonly used in the UK and some other countries. If you cant get it there go find a new job End of the line or EOL.

As a result the line voltage is moved to V2 and charge is removed from the line capacitance to this level as the energy moves down the line. When multiple Contacts are connected maximum resistance will be 1 x Shunt resistor 1 x End of Line resistor no matter how many contacts are connected to the zone. The method just described can ONLY work if the resistor is placed at the end of the line.

Resistor in series allows short circuit detection to provide the appropriate resistance for line fault detection. The end-of-line resistor is there to result in a small current that always flows. This module connects to the Discrete Input channel on the SLS1508 or to LS DI CHARM types that support fault detection and to a field contact.

The End-of-Line resistor is an ordinary resistor.
