The MHY 735 Air Conditioning Adapter is a device of the Electric Fire Detection and Alarm System that is used if detectors have to be protected from the influence of excessive speed air flow (e.g. in an air conditioning conduit).
Adapter for air conditioning is a plastic box with transparent cover with 2 pipes through which air is carried inside the adapter.
Adapter is to be used in case when the detector cannot be installed directly (for example in air conditioning pipelines, when air flows at high speed). When the air flows in the pipelines, it issucked through the input pipe inside the adapter where it is slowed down, so that there are optimal conditions for the detector’s functionality. Sucked air is then released through the output pipe back to the air conditioning pipelines.
Adapter comes in two variants. First one marked MHY 735 with pipes length 170 mm, second one MHY 735.146 for smaller dimensions of pipelines with pipes length 98 mm. Both variants are identical except the pipes length.
To the adapter MHY 735 (MHY 735.146) it is possible to install these types of mounting bases:
- MHY 734 – mounting base for addressable interactive detectors (MHG 161, MHG 162, MHG 243, MHG 261, MHG 262, MHG 861, MHG 862), connected to an addressable control panel(MHU 109, MHU 110/111, MHU 115, MHU 116/117)
- MHY 734.029 - mounting base for conventional non-addressable detectors (MHG 231) connected to conventional control panel (e.g. MHU 113).
- MHY 734.037 – autonomous mounting base with screw terminals. Allows autonomous use of detector outside the FDFAS. Is powered from external power source. For connection ofdetectors MHG 261V, MHG 262V, MHG 861V, MHG 862V. Mounting base’s outputs are relays FIRE and FAULT. Lines are connected to screw terminals.
- MHY 734.038 – autonomous mounting base with crimp connector. All properties are identical as MHY 734.037.
Mounting base and the detector are not product’s accessory and are sold separately.
