6 Repeaters and Master/Slave Network
An ID3000 Series Master/Slave network comprises a
master panel and up to a maximum of thirty one other
network stations, consisting of slave panels and/or
repeaters, communicating via an RS485 serial data link.
The maximum number of panels that can be networked is
eight: one master panel and seven slaves.
6.1 Connecting Repeaters
Each ID3000 Series control panel is capable of
communicating with up to thirty one repeater panels
connected in a ‘daisy chain’ arrangement.
The termination resistor must be disconnected, from all
stations except the two end stations. Do this as follows:
1 If the control panel is NOT an end station, ensure the
jumper link is fitted in position JP1/2/4 (OFF) on the
isolated RS485 PCB - this disconnects the line-terminating
resistor. If the panel is an end station, ensure the
jumper link is fitted in position JP3/5/6 (ON).
2 At intermediate repeater stations, disconnect the line-
terminating resistor as described in the repeater
manual. Repeaters at the end of the network must
have the terminating resistors fitted.
Note: End stations can be repeater panels or fire control
panels (master or slave) or a combination of these,
depending upon your particular system
configuration.
