3. Product description
3.1. InterfacepanelEV-301/EV-601
The interface panels monitor and control smoke control
ventilators and interface devices. With congurable modes
they can operate as a standalone AOV control panel or as
a natural shaft system or as part of a networked mechanical
solution. The panels are addressable and communicate to a
shaft control panel providing status and diagnostics features
via user interface.
It provides powered outputs for smoke vents / dampers
and door actuators with a separate output for dedicated
environmental ventilators.
Interfaces with smoke detectors, re alarm interfaces, overri-
de switches and environmental sensors with line monitoring
of all critical input and output cabling for faults.
3.2. Interface panel EV-301-P
The EV-301-P interface panel monitors and powers smoke
control ventilators and interface devices.
With an integral dierential pressure sensor this panel serves
zones requiring pressure control as part of an addressable
mechanical solution. The panel is addressable and
communi cates to a shaft main control panel providing status
and diagnostics features via user interface.
It provides powered outputs for smoke vents / dampers
and door actuators with a separate output for dedicated
environmental ventilators.
Interfaces with smoke detectors, re alarm interfaces, override
switches and environmental sensors with line monitoring of
all critical input and output cabling for faults.
4. Functionalspecications
The EV-x01 represents the compact control panel system
in the SHEV range. In the standard version, it is housed as
a compact assembly with a single control board in a surfa-
ce-mounted housing.
Mainly AOV‘s and smoke shafts are tted with EV-x01 panels.
There are requirements for optional devices to be connected
such as:
● Smoke detector or Fire alarm signal
● EV-HE077 Override Switches
● SHEV actuators
The EV-x01 essentially consists of three components:
1. Power supply
2. Emergency power supply
3. Control electronics
4.1. Power supply
If the EV-x01 is connected to the mains and supplies the
necessary power from the mains, then this is considered
normal operations (mains operation). The power supply
is designed in such a manner that it can meet the power
demand of the control technology, the battery charging and
can provide power for the connected actuators. It is built as a
switching power supply (SNT).
The power supply is sustained short circuit-proof, sustained
no-load running-proof and is safeguarded by a complying
fuse. The power supply is exclusively cooled by natural air
cooling.
4.2. Emergency power supply
The emergency power supply of the EV-x01 is ensured by
two 12 V lead acid batteries, that are series connected.
During emergency power operation, these take over the power
supply of the control electronics and the connected actuators.
The battery capacity is adjusted to the power supply output
range and is regulated by the individual discharge phases
( BS EN 12101-10). The switching between the two operation
states is automated. The load output for the SHEV-actuators
is represented by two heavy load relays that operate using
the pole reversal technique to ensure the OPEN / CLOSE
control. The outputs are protected by a corres ponding fuse.
During the emergency power operation, appropriate currents
are to be supplied in various phases.
Upon conclusion of this discharge, the discharge threshold
voltage and the under-voltage limit must not be reached.
ATTENTION
If mains is not permanently guaranteed after installation,
there is a big risk of deep discharge of batteries! This will
lead to damage to the battery.
