1 Basic Product Information
1.1 OSD64 Optical Smoke Detector (hereinafter - the detector) is designed to detect fires indoors by the
increase in optical density of the environment when it is filled with smoke. Upon reaching the limit value, the
detector generates an «Actuation» signal. The signal may be reset from the fire alarm control panel.
1.2 The detector is designed for the operation with R3500 series device (hereinafter − the Device).
1.3 The detector complies with EN 54-7.
1.4 The power supply of the detector and communication are carried out via the addressable com-munication
line (hereinafter − the ACL). The detector allows connection to the ACL regardless of polarity.
1.5 The detector performs the following functions:
– measurement of the current smoke concentration;
– interference protection – cutting off the accidental short-term responses of the optical system to particles of
dust, vapour, rime;
– making a decision on the generation and transmission of the «Actuation» signal to the Device;
– making a decision on the generation and transmission of the «Fault» signal to the Device in case of a
malfunction of the optical system;
– measurement of the dust content in the smoke chamber and data generation for transmission to the Device
upon request;
– automatic compensation of the dust content of the smoke chamber;
– making a decision on the generation and transmission of the signal of the dust content limit to the Device;
– indication of the detector statuses (see Table 1);
– testing using the test button or OT-1 optical tester.
1.6 The detector does not respond to changes in the direction and rate of air flow, changes in humidity, the
presence of flame, natural or artificial light.
1.7 The detector occupies 1 address in the system.
1.8 The detectors (Figure 1) are installed in the base type:
W1.02 – with screw-type contacts;
W1.03 – with screw-type contacts and with a pad for securing the cable screen (Figure 2);
W2.02 – with screw-type contacts for the installation on a suspended ceiling;
W2.03 – with screw-type contacts for the installation on a suspended ceiling, and with a pad for securing the
cable screen (Figure 3).
