Description

International Connectors and Cable ICRESVPA3C Compact Module Telephone 8-PORT with RJ31

Overview

The International Connectors and Cable ICRESVPA3C is a compact 8-port telephone module designed to interface alarm systems with standard telephone lines via an RJ31 jack. This module is critical for ensuring that alarm signals can be transmitted reliably over a POTS (Plain Old Telephone Service) line, bypassing any on-site phone extensions that might be in use. It's a straightforward, passive component that isolates the alarm dialer from the rest of the telephone network, preventing line seizure by other devices and ensuring the alarm dialer has priority. This is a common requirement for alarm system installations that rely on dial-up communication for monitoring or notification.

Compatibility

This module is designed to work with any alarm system that requires a standard RJ31X jack for connection to a POTS line. It is compatible with most alarm panels that utilize dial-up communication for central station reporting or remote notification. The RJ31 jack provides a point of demarcation, ensuring the alarm system's communication path is dedicated and not interrupted by other telephone equipment. It is not specific to any particular alarm panel manufacturer but serves as a universal interface for POTS-based alarm reporting.

Installation Notes

Installation involves connecting the incoming telephone line to the module's input terminals and then connecting the module's output (RJ31 jack) to the alarm panel's telephone input. The module is passive and does not require external power. Ensure the incoming telephone line is disconnected before making any connections. The module should be installed in a location that allows for easy access to both the incoming telephone line and the alarm panel's communication port. Proper wiring is essential to maintain the integrity of the alarm signal path.
