Manual Call Point
The manual call point consists of the start-up switch and the corresponding processing circuit. When there is a fire alarm, manually press the button, the button switch is closed, and the alarm signal is sent to the control panel via the loop, and the fire alarm indicator of the manual call point will be changed from flashing (inspection state) to constant light to show the alarm status. If the user controls the sound and light alarm device in the field through the passive normally open contacts of this manual call point, the passive normally open contacts will be closed when the button is pressed, and the alarm device will be activated. The phone indicator on the manual call point flashes if the point gets connected to the fire telephone system.

Product Features

Structure and Dimensions
1) After wiring construction, the base is secured to the wall by pre-buried box or using expansion bolts. The mounting hole distance is 60mm (compatible with 50mm mounting hole distance).
2) The manual call point adopts RVS2×1.5mm2 twisted pair connecting to the control panel.
3) Write address (1-200) to the manual call point using electronic encoder. 
4) Put on the front cover after checking the wiring.
● Terminals 1 and 2 connect bus L1 and L2, and polarity is reversible.
● Terminals 3 and 4 connect phone line, no polarity required.
● Terminals 5 and 6 are normally open contacts. They close when the manual call point button is pressed, and activate the sound and light alarm device. It’s strictly prohibited to use this contact to control high-power equipment or strong electrical equipment.
● Put on the front cover after checking the wiring.
Conduct alarm test regularly, recommended every six months.
