Model TM33 digital tone module provides audio input for any SelecTone® speaker/amplifier. The tone module holds a single pre-recorded voice message, tone or melody. Each tone module contains the latest microprocessor based digital messaging system. This new PCBA module is capable of a 30 second playback of any custom tone or voice message. The tone or message can be reprogrammed at any time with the use of the 300FP field programmer. The model TM33 can either be set to play through once and stop or loop continuously. This solid state digital device will work with Federal Signal speaker/amplifiers (including 50GC, 50GCB, 300GC, 300GCX, 302GC, 302GCX, 300X, 302X, 304GC, 314GC, 304GCX. 314GCX, 304X and 314X) and the 300VSC-1, 300SCW-1, 300VSC-1044SB SelecTone® Command Panels. The TM33's digital messaging capabilities are ideal for emergency evacuation announcements. Clear, concise, predetermined instructions or custom tones can be broadcast. Manufacturing facilities often require an audible signal to indicate status (i.e. Standby, shut down, operational, etc.). Simple pre-recorded melodies can indicate these situations, while voice messages can warn operators.
