SHEVS Control Centre RWZ 5 f

Concept of Control Centre
● SHEVS Control Centre with four outputs for connecting 24 V actuators (RWZ 5f-xx) or 48 V actuators
(RWZ 5f-xx-48V)
● Functions according to EN 12101-10 (power supply), ISO 21927-9 (control), VdS 2581 and VdS 2593
● Selectable group configuration: one or two SHE groups, up to four ventilation groups
● For every SHE group, two signal lines:
− Line
T
: Automatic fire detectors or fire alarm control panel (FACP)
− Line
t
: Manual call points
RT 2
or
RT 4
(main alarm point RT 2/4-*-BS or secondary alarm point
RT 2/4-*). Connectable versions see section 6 “Technical Data”
● Line
Y
for connecting a FACP (activating the alarm in both SHE groups)
● Reset the alarm / the detectors using the button in the main alarm point or in the Control Centre
● Selectable functions:
− “Auto Close” (automatic closure after resetting an alarm)
− “Fault = Alarm” (fault in a signal line will trigger an alarm)
− “Automatic OFF” (automatic travel commands - apart from the alarm - are disabled)
− “Thermal Alarm” (alarm on exceeding an enclosure inside temperature of 70 °C)
− “2-detector-dependency” (2-detector dependency for automatic fire detector in line
T
)
− “WRC” (automatic closure in the case of active wind and rain control)
● Possibility of connecting ventilation button for each ventilation group, also with indication of position
A
● For each actuator output adjustable ventilation position
h
and ventilation time
D
● Possibility of connecting an external wind and rain control, e.g., type
WRS
. Internal wind and rain control, op-
tional
● Internal service display for indicating the detailed status
● The use of K + G / Grasl actuators is recommended. When controlling 3rd party actuators, compatibility is to
be checked. Also note section 6 „Technical Data“ for this
● Connectable actuators: 24 V / 48 V actuators, travelling time for full stroke at rated load (total travelling time)
< 4 minutes
● When directly changing the sense of travel, the actuators are stopped briefly before change of sense
● Sheet steel enclosure, light grey (RAL 7035)

Putting into service / Putting out of service
Work 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 design of SHEVS require observation of the following rules, as far as applicable: National build-
ing codes/model building code and regulations of local building and fire safety authorities, VDE regulations
(particularly VDE 0100, 0108 and 0833), VdS Guidelines 2098 and 2221, DIN 18232, EN 12101, DIN 4102,
model line systems policy.
2.1
Installation / Putting into service
!
Perform work only in de-energised condition!
!
Actuators must not be actuated directly (e.g., with external accumulators during installation / maintenance)
when they are already connected. This can lead to defects in the power output.
● Fasten the enclosure securely to a wall using suitable mounting material. Guide the connection cables
through the openings provided and wire them according to the connection diagrams.
● Make function settings (see 3.2).
