With JP4 in the Siren position the unit will be configured as 2 recordable voice channels and 2 fixed siren sounds. With JP4 in the Voice position, the unit will be configured as 4 recordable voice channels. Voice messages are stored in non-volatile memory and may be rerecorded as needed. Simply configure Jumper JP4 according to your choice of operation and connect according to one of the installation diagrams and the following instructions. SIREN with VOICE mode (Jumper JP4 in the SIREN position) In this mode the 4 channels are split into 2 siren and 2 voice. The siren channels are +S3 (Yelp) and +B4 (Temporal Coded Horn). The voice channels are +V1 and +V2 and have 4 recordable minutes each or 8 minutes combined. Positive (+) Voltage Activation Terminals Each channel may be activated by applying 12 Volts DC between the NEG terminal and the positive (+) input. Both a siren and voice channel may be activated at the same time to achieve mixed siren and voice output. Pulsing Voltage Activation Terminals +S3 and +V1 can automatically detect a pulsed versus a steady activation and play the alternate channel. For example: if channel +S3 (Yelp) is pulsed then channel +B4 (Horn) will be played. If channel +V1 (Voice 1) is pulsed then channel +V2 (Voice 2) will be played. Negative (-) Activation Terminal There is a single terminal marked -VS for controls (eg: DSC) that switch the negative of the alarm output. This terminal automatically plays the appropriate siren and voice combination based upon the input being a steady or a pulse. If the input is a steady negative, the Yelp Siren and Recordable Voice 1 will play. If the input is a pulsed negative, the Horn and Recordable Voice 2 will play. Mixing Siren Sounds and Voice Messages To combine a siren sound with a voice message apply +12 Volts DC to both a Siren input and a Voice input at the same time. EG: To obtain a Yelp siren followed by a burglary voice message, +12 Volts DC voltage to channel +S3 and +V1 at the same time. The two channels will alternately play until the trigger is removed. Exception: Voice channels can be set to play only once per activation cycle by placing jumper JP2 to the 1SHOT position. The siren sound(s) continue until the activation input is removed. Instructions Common To Both Modes Volume and Current Adjust Turning the Volume knob clockwise will increase the output volume. [. . . ] The +V1 and +B3 channel trigger terminals draw only 30 mA each from the control alarm outputs. Standard Method: Control panel with two alarm outputs capable of 2 Amps max. Industrial horn will play if +S3 and +B4 are connected and activated together. Adding a wire jumper between +S3 and +V1 will combine the Horn with Voice 1 Channel. [. . . ]
