Addressing Preparation
The MHY 536 Addressing Preparation is a service preparation intended for setting of addresses and parameters of interactive detectors

The MHY 536 Addressing Preparation is a service preparation intended for setting of addresses and parameters of interactive detectors in the Electric Fire Detection and Alarm System LITES. Can also be used for checking of automatic conventional detectors.

The preparation is intended for change of an address, parameters and checking of interactive fire detectors, interactive action units, addressable unit, technological units and linear smoke detector of analogue fire detection and alarm systems LITES. Allows checking of quiescent current of all detectors and motoric adjustment of optics in linear smoke detector MHG 664. Can also be used for checking of older types of addressable and nonadressable detectors.
The MHY 536 Addressing Preparation is a mobile digital device supplied from a built-in battery that is operated through six buttons. Adjusted and controlled data are displayed on an
alphanumeric LCD display 2 × 16 characters.
Adjustable parameters offered by MHY 536 for particular types of interactive detectors are the same as those offered by configuration program for analogue addressable C.I.E.s.
To the interactive detectors (active elements) can be assigned an address in the range from 1 to 128.

Note: When connecting to C.I.E.s MHU 110, MHU 111, MHU 115, MHU 116 and MHU 117 the detectors are primarily adjusted by C.I.E. according to setting in cofiguration program.

The preparation also allows checking of parameters mentioned below:

  • electrical sensitivity of heat or smoke detectors by automaticly regulated activation voltage UA, (non-addressable and addressable detectors)
  • current consumption of a detector
  • background of optical detectors
  • address of addressable detectors
  • check of parallel signaling

With the preparation it is possible to do measurement on a line that allows checking of addresses of line elements including adjustment and state of addressable and interactive elements.
