Description
The ZPCB2252-MSL is the slave PCB which has no loop interface to the CIE but is directly
controlled by the ZPCB2252-MML board. Up to 7 slave boards can be daisy chained to the master
board and each slave has 32 LED outputs allowing the number of LED outputs to be expanded up
to a maximum of 250 (not all LEDs on the 7th slave are used). The power to these additional LEDs
is also from the external power supply but is transferred through the interlinking cable between
boards.
Cause and effect programming can be uploaded via the RS232 port to the master board to
program how the LEDs will react to command/status information received from the CIE. This
allows the LEDs to not only be used to show fire information but also faults, and can be configured
to trigger by Zone, Panel, Loop or Address.
These boards are typically used for providing visual indications for fire or fault conditions on a site
plan overlay.
