The present document applies to LDC/HR wireless alarm equipment types: • LDC/HR category is defined by the EU Commission Decision 2013/752/EU as: "The low duty cycle/high reliability device category covers radio devices that rely on low overall spectrum utilisation and low duty cycle spectrum access rules to ensure highly reliable spectrum access and transmissions in shared bands. Typical uses include alarm systems that use radio". The present document covers equipment intended for fixed, mobile or nomadic use, e.g.: • stand-alone radio equipment; • plug-in radio devices intended for use with or within a variety of host systems; • plug-in radio devices intended for use within combined equipment. These radio equipment types are capable of operating in the LDC/HR designated frequency bands given in table 1. Table 1: Wireless alarm LDC/HR designated frequency bands Frequency band Transmit and Receive 868,600 to 868,700 MHz Transmit and Receive 869,250 to 869,400 MHz Transmit and Receive 869,650 to 869,700 MHz The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference (article 3.2 of the RE-Directive [i.1]).
