What MS Mikroprozessor-Systeme AG does

MS Mikroprozessor-Systeme AG (MS-AG) is a German B2B manufacturer of alarm transmission, fault detection, and alarm receiving systems, founded in 1982 as MS Elektronik GmbH and headquartered in Krailling near Munich. The company's product portfolio centers on five functional capabilities: capturing state changes from intrusion, fire, or technical systems; controlling responses via relays, remote access, or SMS; transmitting alarms across analog, ISDN, GSM, and IP pathways; alerting up to 250 recipients via voice, SMS, email, or fax with acknowledgement workflows; and visualizing events through Windows-based software (MS LiveGrafix, MS InformationCenter). Its product families include the MS-Digifon elevator emergency call systems (LiftConnect, LiftBox) acquired from KNORR BREMSE AG in 1996, the MSD 4000/4001 alarm receiving computers, and the MSD/MSF 4010 transmission and fault reporting devices. Certification coverage includes VdS, TÜV, ISO 9001 quality management, and EN 81-28:2018 elevator emergency call conformance.

The company operates a direct enterprise sales model with two offices (Krailling HQ and Usingen central sales office) serving the D-A-CH region (Germany, Austria, Switzerland). Revenue is generated through hardware device sales, one-time software licenses for visualization products, and ongoing technical support services. Named customers span verticals: municipalities (Stadt Marburg), retail (REWE Zentral AG), and security services (Wincor-Nixdorf Security GmbH, Niederrheinische Wirtschafts-Überwachung). The company is family-owned, with Ing. Manfred Spiller as Vorstand and Christian Spiller as Aufsichtsratsvorsitzender, and operates with only 7 employees.

• KNORR BREMSE AGfoundationalOthers · 1 January 1996In 1996, MS-AG acquired the product division for transmission and alarm receiving systems from KNORR BREMSE AG, which had pursued a comparable strategy with the protected DIGIFON brand and was considered one of the market leaders in this segment. KNORR BREMSE, as a manufacturer of braking systems for Deutsche Bahn rail vehicles and heavy-duty vehicles, brought absolute quality standards that were incorporated into the MS-AG product portfolio.
• Wincor-Nixdorf Security GmbHmajorTechnology or IntegrationWincor-Nixdorf Security GmbH operates a Notruf- und Service-Leitstelle in Paderborn that receives alarm data from REWE retail markets via MS-AG MSF 4010 transmission devices. Alarms are processed 24/7 by MSD 4000 receiving computers and hazard monitoring software, then responded to according to customer-specific agreements.
• Dr. Pfau Fernwirktechnik GmbHmajorTechnology or IntegrationDr. Pfau Fernwirktechnik GmbH develops the LISA Leitstellen-Managementsystem (command center management system) used by a major German security company. MS-AG's MSD 4000 alarm receiving computers are certified to work 'perfectly' with LISA, requiring only a single interface to be maintained (rather than 13 interfaces previously).
• ELTPLAN GmbHcoreImplementation/ SI/ Consulting PartnerELTPLAN GmbH is a planning firm commissioned by the Stadt Marburg to plan the modernization of the city's fire detection and alarm transmission system. ELTPLAN selected MS-AG as the manufacturer and Team Construction as the installer for the project, which included MSF/MSD 4010 transmission devices and MSD 4000 receiving computers.
• Team ConstructioncoreImplementation/ SI/ Consulting PartnerTeam Construction is the installation contractor (Errichter) selected by ELTPLAN GmbH for the Stadt Marburg alarm system modernization project. MS-AG products were specified and installed by Team Construction.
