Type number
3378 Addressable sounder base (sounder & a special version of analog base 3312)
The sounder: A = Mounting hole (5 x 9.5) for the sounder. Between the sounder and the
ceiling can an 8 mm spacer (Øo = 13) be mounted for easier access of surface mounted cables.
B = Mounting hole (M4) for the base. C = Must not be used. D = Connector for the base
connector. JP1 = Jumper (in position = high output; removed = low output).
Analog detector types 33xx and 430x can be plugged in the base.
NOTE! The COM loop address for 3378 is to be set before the COM loop is connected.
Another COM loop address has to be set in the detector.
