Applied to EN standard, connect to the loop, monitoring the fire protection equipment. When the dry contact of the module is closed, fire alarm or supervision signal is sent to the control panel
JBE-2120 is an addressable input module designed to operate on a loop of intelligent fire detection and alarm devices with the Jade Bird Europe loop protocol. The module is loop-powered and provides one logic input to the fire detection system controlled by the fire panel. This input is electrically isolated from the loop and can be used for monitoring the state of one normally open dry-contact switch. Input modules are often used to monitor third-party equipment such as a door contact. When the input is activated, the LED turns on and the module reports the event to the fire panel.
The JBE-2120 will notify the control panel if there is a disconnection in the pair of cables which lead to the monitored field equipment.
