Application Remote Microphone Specifications
VM-LOCs should be located to provide response personnel and Voltage 21 to 27 VDC
building occupants ready access to the MNEC system. Consoles Current 52 mA
should be used to send messages in emergency situations from Wiring
locations in the building other than from the VM control panel, Type
which in MNEC terminology, operates as an Autonomous Control Audio out 14 to 18 AWG (1.0 to 2.5 mm²) max.,
Unit (ACU). shielded twisted-pair, in conduit
Key out 14 to 18 AWG (1.0 to 2.5 mm²) max.,
LOC Location Guidelines: 1 twisted-pair, in conduit
Resistance 210 Ω max.
• Provide a separate LOC for use by the fire department near Capacitance 1 µF
the building fire alarm control panel (or fire command center) Audio Output 1 VRMS at 400 to 4,000 Hz (4 kHz)
unless this is also the location of the ACU. Trouble relay
• Do not place an LOC inside locked rooms or closets (with the Current 1 A at 30 VDC resistive
possible exception of the operating console intended for use UL rating Common
by the fire department near the FACP). Operating environment 32 to 120°F (0 to 49°C)
Temperature
• Install LOCs at those facility entrances/exits that will be used Relative humidity 0 to 93% noncondensing
when building access is limited during emergency situations.
• Locate LOCs so that occupants do not need to travel a dis-
tance in excess of 200 ft (61 m) horizontally or to other floors
to access one. Remote Microphone Wiring
• Make LOCs available for use by visitors in those facilities open REMICA key in
