4.1.2. Manual call point wiring
The recommended place to install manual call points is on the walls of emergency routes,
with the distance between them not exceeding 25 m. Local regulations may be stricter.
Manual call points must be installed at a height of between 1.2 and 1.5 m from the
floor and be clearly visible, properly labelled and accessible. If the manual call points of
another manufacturer are used, check that they are compatible, e.g. check that they use
an alarm level resistor. Otherwise, it will have to be added (the value of this resistor is
100 ohms 2 W).
Remember that you must place a 4K7 ohm resistor at the end of the line.
4.2. Sounder wiring
CCD-020/040 series control panels have
2 outputs for sounders on the MAIN BOARD
marked as SND1 and SND2 . Each output allows
a maximum current of 450 mA. The wiring
should begin in the control panel's terminal
block and finish in the end-of-line resistor (4K7
ohms).
If any of the sounder outputs are not going to
be used, it is necessary to place this resistor
on the terminals of the sounder output, so that
the system does not signal a fault.
According to the standards, it is not permitted to make a star-connected wire shunt or
install the end-of-line resistor on the terminal block if the sounder output is in use.
