Signals D edicated German Alarm Signals Signals in Set I are used during installation and for service purposes If a Signal Generator Card is being used by for instance an alarm tone in a particular zone and someone attempts to call another zone the CPC will automatically select an alternative SG C to generate the chime signal Because of this it is important when planning a system to have enough SGC s and M atrix Cards to which they are connected to enable it to operate normally in this kind of situation In order for the Central Processor to recognise a SG each unit is given an address T his address setting is accomplished by repositioning a jumper on the Signal Generator Card T he 6 3 mm jack socket located on the front of the SGC allows generated signals to be heard headphones while monitoring during Installer programming A red LED islocated on the front edge of the card to indicate that an alarm tone is sounding a yellow LED indicates that an attention general purpose or time signal is sounding another yellow LED indicates that the unit is in communication with the C entral Processor and 3 green LED s advise that adequate supply voltage is present A screwdriver potentiometer mounted on the card presets the alarm signal volume level and another sets the level of the other signals 2 11 5 SM40 MODULES LIST OF AVAILABLE SIGNALS Signal Set CHIME TONES 01 1 tone chime frequency 02 2 to
