CONNECTION
AND COMISSIONING
4.1 Connections
The connecting elements of the receiver and the transmitter are shown in
Appendix C. To the connectors (are included in the detector set) it is possible to
connect a wire with a cross-section from 0.2 to 1.5 square mm.
4.2 Transmitters connecting
The transmitter can be powered by an uninterrupted power supply of a
(21…30) VDC or from zone of c.i.e. (it is recommended for one transmitter in the
zone; it is allowed for two at a current limit of the zone of at least 25 mA). The
connection methods for both options are shown in Figure 2.

It is possible to connect several transmitters to a single UPS within the power
supply output current Iout (A); maximum number of transmitters n=80*Iout.
It is recommended to use UPS with the output "MALFUNCTION" for
monitoring the condition of the UPS.
The total resistance of the wires should not exceed 250/n ohms.
Transmitter’s green LED should briefly flash 1 time per 5 seconds.
