Abstract: The disclosure includes improvements in the field of retrofit-detector installation such as adapters that simplify retrofit of addressable detectors onto previously installed zone-type system hardware. Each adapter includes electrical circuitry for electrically connecting new addressable detectors with legacy system once installation is complete. The disclosure includes structures that permit users to efficiently solve a number of problems that may arise during installation of retrofit-detectors into legacy systems. For example, one or more switches may be used to reverse electrical polarity to thereby correct polarity and/or mapping faults. One or more switches may also be provided to disconnect at least one electrical terminal to assist in locating ground faults and/or other wiring problems. One or more test points may also be provided to test one or more electrical characteristics relevant to retrofit installations.

Abstract translation: 本公开包括改进检测器安装领域的改进，例如简化将可寻址检测器改装到先前安装的区域型系统硬件上的适配器。 一旦安装完成，每个适配器都包括用于将新的可寻址探测器与传统系统电连接的电路。 本公开包括允许用户有效地解决将改装检测器安装到传统系统中可能出现的许多问题的结构。 例如，可以使用一个或多个开关来反向电极性，从而校正极性和/或映射故障。 还可以提供一个或多个开关以断开至少一个电气端子以帮助定位接地故障和/或其他布线问题。 还可以提供一个或多个测试点来测试与改装设备相关的一个或多个电特性。
