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

●
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

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.
i
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.
