The Novar Friedland wireless alarm system SL5F with accessories (outer solar siren, external control panel, PIR and magnetic sensors, keychain remotes) offers the usual high quality, easy installation and programming. Only the documentation for commissioning could lead a little better. Have elsewhere the previous model (433 MHz) system since 2004 in operation: so far flawless, only once the lead batteries headquarters were to change. Otherwise falls only the battery replacement in the sensors (about every 2+ years), the center reports, which sensor is affected (36 wireless zones ie sensors are possible; this may be for the purpose of partial arming assigned to any two subareas). Conclusion: quality and value for money top, an unconditional recommendation!
