EMS10-EMS50 – Zonable Emergency Microphone
The EMS10, EMS20 and EMS50 Emergency Microphone Stations are EN54 compatible emergency microphones which provide live and pre-recorded message broadcast into user selected zones. The EMS10 provides 10 button selection capability whilst the EMS20 provides 20 buttons, and the EMS50 is formed from a 20 button EMS20 together with an additional 30 button EMX30 expansion unit. All microphones also provide EN54 compliant emergency functions and all EN54 mandatory indicators and controls.
The microphones are housed in a lockable wall-mounting box and feature a graphic LCD display together with indicators for ‘Power’, ‘Voice Alarm’, ‘System Fault’, ‘Fault’ and ‘Speak Now’. The LCD display provides remote access to the list of active faults in the PA/VA system, while the EN54 mandated control keys enable navigation through the fault list, and also provide remote fault acceptance and clearance.
The microphones have multiple PA/VA system interfaces and can be connected directly to either one or two of our audio routers, enabling multiple options for system redundancy. The microphones will operate in an All-Call hardware bypass fallback mode even in the event of processor failure within the host Voice Alarm Router. There is also a licensed, non-EN54 RJ45 Ethernet IP interface with Power over Ethernet capability for VoIP connections to our IP based PA/VA systems. All interconnect cabling and the microphone capsule is continuously monitored for open and short circuits.
Top, bottom and rear cable entry points are provided by means of ‘knock-outs’ in the enclosure, while the field connections are provided by means of a set of terminals on the inside rear panel of the back box.
The EMS10, EMS20 and EMS50 are compatible with our whole range of Voice Alarm and Public Address systems, and are designed to comply with EN54-16, ISO 7240-16 and BS5839-8. An All-Call version is available for applications which require this.
