4. Terminal details

4.1 24V IN/24V OUT

These are the power supply terminals. The polarity of these terminals is very important.

The 24V IN is for connection of the power from a previous unit or a power supply and

the 24V OUT is for connection to further units.

Use a minimum cable size of 1.5mm

and a maximum length of 100 metres or a

maximum cable size of 2.5mm

and a maximum cable length of 160 metres.

Figure 3- Connection of 24V power supply

These terminals are for the connection of a conventional type 24V smoke detector or

other another detection device such as linear heat detection cable.

A 6K8 end of line monitoring resistor is fitted to these terminals. This must be removed

and place across the end of the detection circuit wiring to provide open circuit monitoring

for the detection cable.

Note: automatic smoke detectors are polarity sensitive so polarity should be observed. If

a short circuit take place over the detection line (either by linear heat detector activation

or smoke detector activation [470 Ohms] or by accident), then the panel will

immediately proceed to activation
