Introduction:
The SE Controls range of
control systems are built
and tested control panels
specically for Smoke and/
or Environmental Ventilation
Systems and for use with SE
Controls supplied equipment.
They must not be used for any other
application or in conjunction with
other manufacturers’ products without
prior consultation with SE Controls.
Application:
The SHEVTEC PSU Panel is a
powerful 24 Volt DC control
system designed for 2-wire
24V DC actuators in a smoke
control and/or environmental
ventilation system.
Operating from a 230VAC supply,
the SHEVTEC PSU Panel can deliver
up to 30/60/90 Amps to drive
24 Volt motorised actuators.
The SHEVTEC PSU Panel can be
mounted in a centralised plant
room location. Each SHEVTEC PSU
Panel can operate independently
or be linked to others to produce
a networked control system. The
networked control system in turn
can operate standalone or be linked
to a building management system.
Installation of this equipment must
only be carried out by competent
and qualied persons.
The Installer and user are requested
to read, understand and retain
this information pack with the
panel for future reference.
This information pack must be
retained for future reference by
the client and be made available
for reference by persons installing,
servicing or modifying the panel.

3. Connections
3.1. Power and control connections
All terminals have a cable capacity of
2.5mm2 stranded or 4mm2 solid. Each
terminal is identied with a 3 letter code
which is expanded on the terminal label.
Do not interfere with xing or
location of the thermistor.
The following sections are to be used for
guidance only and are subject to change.
All external switch contacts are to be volt-free
and capable of carrying 24VDC at low currents.
The maximum cable length for digital
control input signals is 500M.
0-10 Volt signals must remain stable and
‘spike’ free for a period of 2 seconds before
the controller will respond to them. In 10%
step mode, the controller only responds to
0-10V signals in steps of whole volts ±250mV.
In 5% step mode, each step is half a volt.
Environmental ventilation accessories (e.g. rain
sensors) should be powered from the AUX supply.
Essential smoke accessories (e.g. smoke detectors)
should be powered from the PER supply.
Strip the outer sheath of all cables back to the
entry point of the enclosure. Ensure enough
sheath is left to provide mechanical protection
against cable movement over time.
Inner cable cores should be dressed under the
edges of the power and control board. This
provides a neater and more ordered solution.
Only strip inner cores suciently to make a good
electromechanical contact with the terminal blocks.
Where multiple actuator leads are to be
connected to the controller, it is advisable to use
an external junction box to reduce the number
of cable glands required, if using screw-terminal
joints ensure they are of the enclosed type.
The default controller settings have been chosen
to cater for the majority of applications. If alternate
settings are required please contact SE Controls.

3.2. Actuator connections
The 30A PSU has four separately fused 24VDC actuator output channels. Each
output channel has terminals for connecting up to 4 actuators.
The default mode of operation of these outputs is timed o, reversing polarity and is intended
for use with linear and chain actuators. Locking catches, magnetic catches and rotary dampers
can be used but require changes to the default settings of the controller by SE Controls.
Output mode - timed o, reversing polarity
Actuator Full Stroke Period (Environmental Ventilation) - 40 seconds
Alarm Full Stroke Period (Smoke Vent) - 180 seconds

3.3. Manual Control Points
These switches are used to manually open and close actuators in a smoke control system. There is
a set lock-out period of 5 seconds between successive operations. The actuators open full stroke in
response to a transitory operation of the Manual Control Point. However, to prevent nger trapping
issues, the actuators only close whilst the Reset button on the Manual Control Point is maintained.
Note that the default Manual control point close mode can be changed by SE Controls to close
fully in response to a brief press of the reset button. This mode change is only recommended
where the activated vent is at least 2.5M above ground level to minimise nger trapping issues.
OS2 MCP Part Number FCS00200016
OS2 Tamperproof MCP Part Number FCS00200034
OS2 MCP Adaptor Plate Part Number FCS00200017
All connections to the OS2 MCP are made via the connection PCB mounted
within the adapter plate assembly. (See diagram below.)
The connection PCB has 14 terminals, consisting of 2 pairs of 7 connections. For
OS2 products, it is only necessary to connect to 5 of these signals as follows:

3.4. Fire Alarm Inputs (FRA, ARA, SMK)
All re alarm input signals require a Normally Closed volt-free-contact which
opens on re signal initiation. The unit comes with all alarms hardware disabled
via jumper links. To enable an alarm input, refer to the gure below.
Each re alarm input has dierent functionality. It is not mandatory to connect a particular type of
device to a particular re alarm input, but to the one(s) that provide the required functionality.
Fire Alarm - Opens on activation; Use of reset from Manual control is allowed.
Auto reset Fire Alarm - Opens on activation; Use of reset from Manual control
is allowed; 30 second lock-out period after activation before reset; 120
second lock-out following reset before subsequent re-activation.
Smoke Detector Input - Opens on activation- Does not allow use of
reset from Manual control until alarm has been reset.
The alarm activation direction, Manual control point’s Switch reaction
mode and lock-out periods can be congured by S E Controls.

3.5. Smoke Detectors (SMK)
Smoke detector heads are required to provide a normally closed volt-free contact. Smoke
detectors should be powered from the PER supply rail. The recommended maximum
number of Smoke detectors is 5 connected to a single SHEVTEC PSU PANEL.
It is important that the quiescent current of the smoke detectors is kept to a
minimum as their current draw will greatly impact on standby times. The peak
current draw on the PER permanent supply should never exceed 1Amp.
Intelligent Optical smoke detector ADA55000318 (Head) ADA45681245 (Base)
This smoke detector is an exclusive S E Controls product and has been specically
designed to operate as part of SE Controls SHEVTEC systems. It has been
marked as such to aid in identication for servicing and replacement.
Other models / types are not suitable products for use in SHEVS and are not compatible.
The new detector is a 2 part assembly comprising a head and a base which clip
together. To prevent interference by unauthorized persons the base incorporates
a locking mechanism which then prevents disassembly without a tool.
The detector head has an LED indicator to provide status information. Distinctive markings
on the head set it apart from other standard types of detector, and each unit is supplied
with a clip-on dust cover which should be removed at commissioning stage.
Single
Multi
Removal of the head DOES NOT cause activation of the system. Once installation is complete,
ensure lock is engaged to prevent unauthorised removal of detector head
The current model is NOT suitable for use with SHEVTEC PSU PANEL Auto Reset alarm
functions. Please seek further advice from SE Controls if this facility is required.
Test using Canned Smoke or other approved smoke generating method. No other method is acceptable.

3.6. Day to Day Switch (DYO, DYC)
Connecting terminals DYO and DYC to 0VP will open and close the vent in environmental ventilation
mode. The default mode requires a spring centre 3 position switch having 2 normally open contacts.
The actuator will only move whilst the input demand is in force and the total movement time in the
requested direction is less than 18 seconds (default). Releasing the switch will stop the movement.
The day-to-day inputs only operate whist the controller is in manual operational mode.

3.7. Thermostat (TST)
A simple volt free room thermostat can be used to operate the SHEVTEC PSU PANEL. The
output contact is required to close when a demand to open a vent is required.
When the demand is received, power is applied to the actuator outputs for 40 seconds in the open direction.
When the demand is removed, power is applied to the actuator outputs for 40 seconds in the close direction.
Both of these movements are subject to a 180 second lockout period which prevents frequent unwanted operation.

3.8. BMS Analogue Input (AI1)
A 0-10V BMS analogue demand input channel is provided. It has a 100K input impedance plus a 50ms
anti-aliasing lter. By default, the input is congured to set the actuator position in 10% steps based on a
scaling of 1V==10%,where 100% is the natural ventilation maximum run time (default 40 seconds).
Other input scaling is available. Please refer to SE Controls for details.
A second analogue input, AI2, having the same characteristics as AI1 is
available. This is not used in the default system conguration.

3.9. Rain Sensor (RNS)
An input for the connection of a volt free normally open rain sensor is provided. When the contact
closes, power is applied at the actuator outputs in the close direction for a period of 180 seconds.
At the same time, a 180 second lock-out timer is started. If either the rain sensor remains wet or the lock-
out timer is running, the environmental ventilation controls are ignored. Once the rain sensor dries out and
the lock-out timer times out, the environmental ventilation controls are re-enabled. However, note that the
position of the vent is not automatically reset to the last known position prior to the rain sensor activation.
The rain sensor input can also be used to close the vents from a centralised
control point, by the use of a 7 day timer or a caretaker switch.
