4.14 Addressable Dual Loop Termination Board
The Addressable Dual Loop Termination Board (BRD86DLTB) acts as the interface between the
external addressable devices and the control and monitoring functions of the FireFinder PLUS. Each
board provides terminations for two loops and can be used with the Apollo range of detectors. One
slave CPU is required per loop.
Note: Apollo devices L2 is +ve (positive), L1 is -ve (negative)
AMPAC strongly recommend that the LoopManager test set is used to check that the Apollo loop has
been correctly installed and commissioned before connecting it to the FireFinder PLUS.
Loop Parameters
➢ 126 Apollo Devices (i.e. maximum address range)
➢ When using Alarm Acknowledgement Facility’s (AAF’s) a max of 50 per Loop
➢ 500mA Current Max
➢ S/C protection circuitry activates at approximately 650mA
➢ Maximum length 1.2km
Note: To achieve full current, the Loop Trip current in Loop Parameters needs to be set to 300mA
