J-SAB-JBF4121G-Ex

Overview
The manual call point is connected to the two-wire fire alarm system with the JB 11SF series control panel. The device has 1 set of passive contacts that activate alarm appliances like sounder beacons in the field. The application design follows the national standard GB 50116 "Code for design of automatic fire alarm system".

Structure and Installation

Note: Explosion-proof cable introduction needs to be purchased by users, and its explosion-proof rating must meet IIC:
Cable introduction: JBF-CGP-M20 (explosion-proof rating: Exd IIC)
Block off plug: JBF-Hp-M20 (optional accessory)
•  The corresponding address code (1-200) must be written to it by an encoder before installation.
•  Connect terminals L1 and L2 (polarity-free) to the loop.
•  After wiring construction, fix the manual call point to its installation position.
•  The installation should be carried out before the system commissioning and after the wiring inspection to avoid loss caused by improper installation work.

Precautions
•  The internal and external grounding must be reliable.
•  Do not replace any components or adjust the structure of the manual call point, which will affect explosion-proof performance.
•  When repairing and maintaining, pay attention to protect the explosion-proof surface. Make sure the surface not damaged or rusted.
•  Do not open the housing when the device is powered on.
•  Non-professionals are not allowed to install or uninstall the product.
•  Conduct alarm test regularly. Recommended cycle is six months.
