The MHY 535 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. Can also be used for checking of older types of addressable and nonadressable detectors.
The MHY 535 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. It is used when putting electrical fire alarm equipment into service, service repairs and maintenance, periodic inspections of serviceability etc.
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)
- 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. Alco san me used as an DC voltmeter.

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.
Note: * With developement of new types of detectors, the upgrade of firmware is needed. Preparation with out of date firmware allows only change of an address.
** This preparation dos not support the function of motorical optics adjustment
| WORKING CONDITIONS | |
| Preparation is suitable to use in areas protected against weather conditions with classification according to ČSN EN 60721-3-3: | |
| K: climatic conditions for environment | 3K3 |
| - working temperature range | +5°C to +40 °C |
| - max. relative humidity | ≤ 80 % at 40 °C |
| - without condensation and ice accretion | |
