HOMOLOGATION AND INSTALLATION
Homologation
- Complies with the standards EN 61779-1-4; CEI 216-5/1 Directives/Norms EMC EMC 89/336/CEE, Norm EN 50270.
Installation and use- Rear panel mounting on Omega DIN EN 50022 rail.
- It can be installed on the bottom panel or DIN modular panels.
- To ensure the proper protection degree of the device is necessary to install the unit in an electric box created according to current regulations for the workplace and within which can also be housed the power supply system.
- P81 control unit allows you to connect a probe model S81-82-83 or ATEX S84, S85, S86 probes for the construction of gas detection systems in environments such as boiler rooms, garages, warehouses, workshops, etc., with the possibility to control a solenoid valve or an auxiliary device (siren, flashing light, extractor, etc..) through inside alarm relay.
- The control unit must be powered at 12 Vac/dc.
- The functioning logic, selected by means of jumper E1, can be either positive or negative. The device reports its operation status through the LED.
