Concept of Control Centre 

  Smoke and Heat Exhaust Ventilation System (SHEVS) Control Centre for the connection of 24

V- actuators 

  VdS approved (to VdS 2581 and VdS 2593) 

  Internal power supply designed and certified to DIN EN 12101-10 

  Control unit designed and tested to prEN 12101-9 

  One SHE group, two signal lines: 

 Line 

T

: automatic fire detectors or Fire Alarm Control Panel (FACP) 

 Line 

t

: manual call points

 (alarm / malfunction) and indication of position 

A

 also 

possible 

b) Secondary alarm point with indicator alarm 

r

 

  Reset the alarm / detector using the button in the main alarm point or in the Control Centre 

 Selectable functions: 

  “Auto close” (automatic closure after resetting an alarm) 

  “Malfunction = Alarm” (alarm upon malfunction of a signal line) 

  “Automatic OFF” (automatic travel commands - apart from the alarm - are disabled) 

  “Thermal alarm” (alarm on exceeding an enclosure inside temperature of 70

°C) 

  Possibility of connecting ventilation buttons, also with indication of position 

A

  

  Adjustable ventilation position 

h

 and ventilation time 

D

 

  Possibility of connecting an external Wind and Rain Control (WRC), e.g. type 

WRS 

(for each SHEVS Control 

Centre to be controlled, a separate contact is required). Optionally internal Wind and Rain Control 

  Internal service display for detailed status information for installation and maintenance 

  Plug-in connection terminals (apart from actuator output) 

  The use of K + G / Grasl actuators is recommended. When driving third-party actuators, compatibility is to be 

checked! Also note Section 6 “Technical data” 

 Actuator specification: 24

V actuators, travelling time for full stroke at rated load (total travelling time) < 4

min. 

  Actuators must be suitable for the repetition of OPEN and / or CLOSE cycle (see 3.4.2 / 3.6) 

  Upon direct change of the sense of travel, the actuators are briefly stopped before changing the sense 

  Sheet steel enclosure, light grey (RAL 7035)

Options / Accessories 

 

PK:

 One potential-free contact (PFC) each for alarm / malfunction forwarding 

 

WRM:

 Internal Wind- and Rain Control 

  Actuators are automatically closed on response of WRM. Connection of wind sensor 

WM

 and / or rain 

sensor 

RS

 is required (accessory) 

  Direct connection of the sensors on the module in the Control Centre. No external WRC required 

  Sensitivity of the sensors is adjustable 

  The closing command remains active as long as a sensor responds, but for at least 6 minutes 

  Indicators for wind 

W

 and rain 

R

 on the module 

i

  As there are no corresponding regulations, the optional board WRM is not VdS approved. However its usage 

does not affect the VdS approval of the Control Centre, since interactions have been checked and excluded 
during the approval process.

Putting into service / putting out of service 

Work at the Control Centre may be performed only by qualified personnel! 
Before starting any work it is mandatory to deflect static charge! 

We do not assume any guarantee or liability for defects caused by faulty connection.

Planning and installation of SHEVS require observation of the following rules, as far as applicable: national 
building codes / model building code and regulations of the local building and fire safety authorities, VDE 
regulations (particularly VDE 0100, 0108 and 0833), VdS Guidelines 2098 and 2221, DIN 18232 and EN 
12101, DIN 4102, model line systems policy.
