1OVERVIEW
The BKT EMS system is designed to monitor environmental parameters (temperature, humidity, etc.) in a telecommunications cabinet or small
rooms. Its purpose is to warn users about possible emergency situations and report any failures. The single system controller can support: up to
4 analogue sensors, 4 sensors with potential-free contacts and two signalling devices. With expansion modules there are up to 28 analogue
sensors, 68 sensors with potential-free contacts, 10 sensors with CAN bus interface. To keep a satisfactory system performance, it is not
recommended to connect more than 60 sensors to the controller.

3.5 Example 4. IT cabinet monitoring
An example of an environmental conditions monitoring system in cold aisle containment built of 6 cabinets: temperature (ES350) and humidity
(ES351) in the aisle, temperature at the top of the cabinet, humidity and presence of smoke (ES340). A flood detection sensor was placed under
the floor (ES360 + ES368).
The CAN bus connection, the length of the entire bus
is up to 200m
The connection of an analogue sensor, the length for
each sensor: minimum 50m

4.2.2 Assembly procedure
The method of assembling the modem is shown below.
Cut the cover on the back of the controller using, for example, side cutters.
Carefully slide the modem pcb into the controller.
Install the bayonet antennas on the modem.
Place the microSIM card in the module with the contacts facing down and the cutout
facing the inside of the controller. Push the card until it clicks.
To remove the card, push it in again until it clicks.

4.3.5 Connecting the EE321 module
The devices should be connected in a cascade (from one device to
another). The CAN socket number is irrelevant, either CAN1 or
CAN2 can be used. The maximum CAN bus length is 200 m.
1. Connection of sensors to a device extending the
number of analogue inputs.
2. Connection of 12VDC/1A power supply.
3. Connection of a CAN bus to the EC335i controller.
4. Cascade connection of the CAN bus (from one device to
another).
For CAN bus connections, UTP cat5e cable terminated with
RJ14(6P4C) - RJ14(6P4C) plugs.
FR-off, TR-on FR-off, TR-off
The bus terminator in the last device (from the controller) must
be enabled. The bus terminator in the other devices must be
disabled. The TR switch (activating the terminator) in ON and OFF
position is shown in the drawing on the left.
The FR switch is for servicing and must be in OFF position during
normal operation.

The EE321 module has two LEDs that signal the states:
ERR is on, RUN flashes - the EE321 module is not connected to the
controller
ERR is on, RUN is off - the EE321 module is connected to the
EC335i controller but is not configured correctly in the controller
ERR is off, RUN is on - the EE321 module is connected to the
EC335i controller and is correctly configured in the controller
