Built in microprocessor, Stable performance. SMT surface mounting process, high reliability and good consistency. Adopting two-bus system, no polarity requirement, ensuring low power consumption while making the transmission distance up to 1000m. Electronic encoding, addressable by a special electronic encoder. The operation is simple. Press the operation panel by hand to realize the fire alarm report to the controller. To reset the operation panel on the manual alarm button after pressing it, the special key matching the button must be used. Manual alarm button adopts new buckle structure and thin design. The phone jack is located at the bottom, and a logo guide is added on the front of the button for easy identification.
After wiring construction, the base shall be fixed on the wall through embedded boxes or expansion bolts, and the installation hole spacing is 60mm (compatible with 50mm installation hole spacing). The manual fire alarm button is connected to the controller by RVS2 x 1.5mm2 twisted pair cable. Before installation, use the encoder to write the corresponding address code (1-200). After wiring and checking, buckle the upper shell.
Terminals 1 and 2 are respectively connected to loop two buses L1 and L2, and have no polarity. Terminals 3 and 4 are connected to telephone lines without polarity. Terminals 5 and 6 are normally open contacts, closed when the manual fire alarm button is pressed, which can be used to control the on-site audible and visual alarm device. It is strictly forbidden to use this contact to control high-power equipment and strong current equipment.
