Description The HM201-SW Addressable Input Module is a compact and reliable device designed for use in addressable fire alarm and security systems. It allows the monitoring of normally open contact devices, enabling seamless integration of external equipment such as manual call points, fire alarm inputs, and security devices into an addressable loop. The module is designed for installation in a single-gang junction box, directly behind the monitored device. Its small size and lightweight construction allow for flexible installation without the need for rigid mounting. Each module features a unique address stored securely in the MCU’s EEPROM, ensuring accurate identification and communication within the system. The HM201-SW operates on a two-wire initiating circuit and is compatible with addressable, two-wire systems. Built for dependable performance, the module provides stable monitoring and must be connected only to listed, compatible addressable fire alarm control panels.
