The electrical connection options for the input to the unit are shown in Figure 1. The various electrical input configurations allow a user to select under what condition the unit will be ‘triggered’ to provide a signal the fire alarm system indicating the selected condition.5N.O.The four different behaviours can be configured by DIP switch 5 and 6 in order to be able to monitor different setups of the input contact (s). (Switch 8 is not used).2KOhmON OFF6910 Ohm1 2 3 4 5 6 7 8(See location of DIP switch S1 on the circuit board drawing)Input configuration B5N.C.2KOhmInput configuration A activates when the contacts are closed. This arrangement also allows the unit to monitor for an electrical wiring fault in the form of an open or short- circuit, between the contacts and the unit, either before or during activation.
