Description
Note: Quantity in packing of 180 pieces.

It is intended for control of temperature of the gas environment of rooms of buildings and constructions and issue of the notice on the fire in case of excess of temperature of operation of the announcer. The announcer is also allowed to apply in intrinsically safe chains (loops) of the reception and control devices having the corresponding marking on explosion protection.

The announcer with the normal closed contacts of the class A2 with temperature of operation from 54 to 70 a hail. on NPB 85 - 2000.

Functionality and features

  • It is tolerant to influence of magnetic fields that allows to use it at power plants, power distribution points, near powerful consumers of the electric power.
  • The optimum arrangement of a thermosensitive element in the case of the announcer corresponds to conditions of early detection of an initial stage of the fire.
  • Possibility of use in explosive rooms by inclusion in a loop of devices of reception and control security and firefighters with a type of explosion protection "an intrinsically safe electric chain" of UPKOP 135 - 1 - 1 (BIV v.3, v.4, v.5), UPKOP 135 - 1 - 2P.
  • In the announcer of IP114 - 5 the thermal element with effect of "shape memory" changing the geometrical sizes at temperature increase of the environment is established. At excess of a threshold of operation mechanical impact on the compensating spring is resulted by disconnection of contacts of the relay. At fall of temperature contacts of the relay come back to a starting position. Thanks to such constructive decision of SP 114 - 5 is a netokopotreblyayushchy announcer.
  • When calculating number of announcers in a loop of the reception and control device it is necessary to consider the transitional resistance of the announcer which does not exceed 0,5 Ohms.
