Chapter V Voice Module
Voice alarm function, telephone control function and dialing automatically
function are very important functions of SR. To realize these functions, we should
match SR with the SR-VP voice module. Voice module blocks have two types:
SR-VPA (AC Type), SR-VPD (DC Type).
5.1 Structure of Voice Module
Fig. 5.1 Structure of SR-VP Series Voice Module
1. Connecting port between voice module and the machine
2. Connecting port between voice module and communication cable
3. MIC (Users may record through this place when recording off-line or through the
front panel.)
4. SR (Speaker broadcasting interface which the voice module self-carrying)
5. Voice module on-line recording audio input port
6. Socket of telephone crystal plug
7. Indicator of the power and recording of the voice module (It will be on green
when the voice module is powered on-power indicator. It will be on red when the
voice module begins recording-recording indicator. When recording, users must
wait till the recording indicator is lighted and stop when it is off. Otherwise the
voice can’t be recorded.)
8. Power input (AC or DC) (100-240VAC), (12-24VDC)
9. Audio output port (to be connected with the acoustics)
5.2 Connection between Voice Module and SR
SR-VP type voice module can be connected with the SR series machines
through SR-CB. Pay attention that only the machines of the same type can be
connected together. That is to say that SR-VPA, AC type, can only be connected with
AC type machine and SR-VPD, the DC type, can only be connected with DC type
