Connection method:

1, Z 1, Z2: connected to the signal bus of the fire alarm controller, with no polarity.

2.D 1, D2: DC24V power supply input terminal, nonpolar.

3.I and G: connected to the passive normally open contact of the controlled equipment, used to confirm the response of the equipment (it can also be set as normally closed input or self-response through the electronic encoder).

4.COM, NO: Passive normally open output terminal (Note: there is a weak line detection current between these terminals! ! ! )

5, NG, S-, V+, g:: reserved

Wiring requirements:

The signal buses Z 1 and Z2 adopt flame-retardant RVS twisted pair, and the cross-sectional area is ≥1.0mm2; Power lines D 1 and D2 are flame retardant BV lines with cross-sectional area ≥1.5mm2; G, NG, V+, NO, COM, S- and I use flame-retardant RV wires, and the cross-sectional area is ≥1.0mm2. ..
