Zoneable Fireman’s Microphone Stations
Product Description
The FMS5, 10 and 20 Fireman’s Microphone Stations each comprise a lockable wall-mounting box housing a
fist microphone and associated electronics. All are designed to work with the VAR range of DSP
Router/System Controllers.
The FMS5 provides 5 zone selection capability whilst the FMS10 and 20 provide 10 and 20 zones
respectively. Buttons may also be configured to broadcast pre-recorded messages.
The FMS5-20 will operate in an all-call mode even in the event of processor failure within the router as
required by BS 5839 Pt.8. In this instance, the All-Call-Only indicators will illuminate to indicate the restricted
function.
Interfacing of Select buttons and indicators to the DSP Router/System Controller is via an RS485 serial
connection.
Microphone audio is provided as a balanced 0dBu (nominal) analogue signal. The unit features an in-built
signal limiter.
The microphone capsule is continuously monitored for open or short circuits. An outgoing 20Hz surveillance
tone is generated to enable the audio cabling to the router to be monitored.
Hardwired connections are provided for the PTT switch and Speak Now and All-Call-Only indicators. This
cabling is continuously monitored by the router for open and short circuits.
Field connections are provided by internal DIN rail mounted terminals on the back of the box.
Top and bottom cable entry points are provided fitted with removable metal blanking plugs. Rear cable entry is
also catered for by means of ‘knock-outs’ in the rear of the box.
For further details please refer to the DSP Router/System Controller Handbook and the Application Solutions
PA/VA Systems Design Handbook.
