9 Switch loop

Up to 4 contacts can be connected to the fire alarm control panel. Each operating panel and the

fire alarm control panel itself has a monitored input loop to accommodate them, and can be used

for example for reading a reset switch with a triangle key as used in the Netherlands, or an

external buzzer stop switch. The loop is fully monitored for short circuits and line breaks.

The end of line resistor must be connected directly to the main PCB if the input loop is not used.

10 Pager output / serial connection with the PC

PC connection for setting up the control panel using the CMPlus.exe program or for use as a

pager output. The CM+ selects the correct mode automatically.

Use screened cable; maximum cable length is 2.5 m (RS232 5 V levels)

10.1 Pager settings

Only data is output in this mode – connect the pager to the Do and GND terminals.

The Di terminal is used for automatic selection of the mode; it is safer not to connect this to a

pager system.

RS232 settings: 9600 baud, 8 data bits, 1 stop bit, no parity.
