- UL Recognized
The Federal Signal Single Message CommCenter® Model 300SMB provides a single 16-second digital message.
Melodies, voice messages, tones and signals are available, including the prerecorded CommCenter Standard
Library or custom recorded messages. The Federal Signal Model 300MCDK can be used to record custom messages in the field.
The 300SMB CommCenter is suited for price-sensitive, single-message OEM applications. The 300SMB is
a board level device that can be incorporated into an OEM product.
The 300SMB Single Message CommCenter is preset for initiation from a normally open (N.O.) momentary
contact. A jumper setting on the PC board allows the initiation input to be changed to a normally
closed contact. Another jumper switches the unit from a momentary contact to a latched contact. A
momentary contact plays the message through for as long as the contact is held and finishes the final
message. A latching contact plays the message as long as the contact is held, stopping mid-message if
the contact is removed.
The 300SMB has both a 10Vrms (unbalanced) output and a 25Vrms (balanced) output. The 10Vrms output
is useful when utilizing existing SelecTone® speaker amplifiers and connector kits. The 15-watt,
25Vrms output can drive 15 watts of transformer coupled speakers or AM25CK connector kits used with
SelecTone speaker/amplifiers. When used with AudioMaster® transformer-coupled speakers, or the AM25CK,
the 25Vrms output creates a balanced line and helps provide noise-free audio output. Volume adjustment
controls the sound level.
A single 300SMB is capable of driving two 8-ohm speakers.
