The MSP–300 wireless outdoor siren is designed to work in conjunction with the MTX–300 controller as well as PERFECTA 16–WRL and PERFECTA 32–WRL control panels, operating at 433 MHz frequency. The modern SPIRIT1 radio system with optimized power management, which enables long–lasting operation of the device in harsh environments, has been used in the siren. Trouble–free functioning of the MSP–300 is also possible due to the BAT–ER–3,6 high–performance battery, which is used in specialized applications, including military and medical ones.
