Inovonics EN1210EOL End of Line Resistor Transmitter

Product Description

The INOVONICS EN1210EOL is a universal transmitter end-of-line resistor designed for use in wireless door and window contact applications. This component integrates directly into a transmitter circuit to provide supervised loop monitoring, allowing the system to detect open, closed, and tamper conditions on a single zone input. It is used by security and low-voltage technicians during installation or service of wireless alarm systems where end-of-line supervision is required by code or system design.

The EN1210EOL is suited for residential and light commercial wireless security installations where door and window contacts require supervised inputs. It is compatible with Inovonics transmitter-based detection devices used in supervised wireless sensing applications. Installers working with supervised contact loops will use this resistor to complete the required end-of-line configuration on compatible wireless transmitters.

Key Features

• Provides end-of-line resistor function for supervised wireless door and window contact transmitters
• Supports open, closed, and tamper state detection on a single supervised zone
• Universal design intended for use across compatible Inovonics wireless transmitter platforms
• Compact, single-unit component for straightforward field installation
• Sold individually for precise quantity ordering

Compatibility

Designed as an OEM-style accessory for use with Inovonics wireless door and window contact transmitters that require end-of-line resistor supervision.

Installation Notes

Installation should be performed by a licensed low-voltage or alarm systems technician familiar with supervised contact loop wiring. De-energize the transmitter and follow the manufacturer wiring diagram before connecting the end-of-line resistor. Consult local codes and the applicable National Electrical Code articles governing low-voltage alarm wiring before beginning work. Do not substitute resistor values not specified by the transmitter manufacturer, as incorrect resistance will cause false supervision faults.
