B1 - B9 Bases

The list of bases, their differences and the way of connection are specified in the table.
 

Bases B6, B7, B8, and B9 are end-of-line, installed singly at the end of each loop and used in 4-wire alarm loops for the control of presence of power voltage and the integrity of circuit.

The connection of a detector to a control panel with a 2-wire alarm loop is realized by means of bases B01, B1. The connection of a detector to a control panel with a 4-wire alarm loop is realized by means of bases B2, B3, B4, and B5.

The B1-B9 bases  are designed for the connection of the SPD-3.10 smoke detector  to various types of fire alarm loops 2-wire with remote output or without it, 4-wire with N.C. /N.O. relay contacts.
