3. Components of the DICTATOR Hold-Open System

The explosion-proof DICTATOR hold-open system is made up of maxi-

mum 20 smoke or heat detectors and up to 12 explosion-proof magnets

(ATTENTION: consider the maximum output load of the RZ-24 central!).

Components:

- RZ-24 central unit with power supply, part no. 040553

- Shunt safety barrier: Zener barrier Z779, part no. 040589

- RM 3000IS EX smoke detector or WM 3000IS EX heat detector with

base, part no. 040881SET or 040886SET

- Resistor 3.9 kΩ (included in the scope of delivery of the RZ-24 central)

- Explosion-proof magnet (DICTATOR electromagnets EM GD 50 EX or

EM GD 70 EX, either with connection cable or terminal box, or EM

GD 70 R 39 I, Ex2) - see separate manual

- Ex-proof hand release switch, part no. 700232, and outside the

hazardous area (upstream of the Zener barrier) hand release switch,

part no. 040005, or the key on the RZ-24 central

- Gas warning system (the need to be clarified on the basis of the on-site

requirements)

In order to open a fire protection door automatically an approved,

explosion-proof door operator can be used. In explosion-proof hold-open

systems the magnets are generally installed only in the OPEN position

of the door and are not integrated in the door operator.

In the case of an alarm it has absolutely to be made sure that the door

closes and is not blocked due to an error of the control system. Therefore,

in such a case, the RZ-24 central automatically switches off the control

system of the ex-proof door operator.

Components:

- RZ-24 central unit with power supply, part no. 040553

- Shunt safety barrier: Zener barrier Z779, part no. 040589

- RM 3000IS EX smoke detector or WM 3000IS EX heat detector with

base, part no. 040881SET or 040886SET

- Resistor 3.9 kΩ (included in the scope of delivery of the RZ-24 central)

- Explosion-proof magnet (DICTATOR electromagnets EM GD 50 EX or

EM GD 70 EX, either with connection cable or terminal box, or EM

GD 70 R 39 I, Ex2) - see separate manual

- Ex-proof hand release switch, part no. 700232, and outside the ha-

zardous area (upstream of the Zener barrier) hand release switch, part

no. 040005, or the key on the RZ-24 central

- Gas warning system (the need to be clarified on the basis of the on-site

requirements)

- Ex-proof door operator for opening the door by motor

- Door operator controller

When installing the components, you have to adhere to the respective

operating and mounting instructions and the directives for hazardous

areas.
