Type B fire sound and light alarm is a coded sound and light alarm equipment installed on site. After addressing, it can be directly connected to the alarm controller loop, incorporated into the fire alarm controller management of the fire control center, and participates in fire linkage. When B is activated, an audible and visual alarm signal is emitted to remind on-site personnel to pay attention. It is usually installed in public corridors, buildings, and gas fire extinguishing places. () Performance features:
*The on-site sound and light alarm equipment is managed by the fire alarm controller of the fire control center
*B has built-in high performance and adopts a new generation of bus technology. It will send out sound and light alarms after action. Signal
*Adopt special process control for moisture-proof treatment, so that it can work normally in coastal areas, humid and harsh environments: >Two bus system, installation without polarity, convenient for on-site construction
* Occupies one module class Address (~)
* Encoded using electronic encoding, easy to operate.
