Hydrogen sensor








Some concepts in the battery technology can sometimes "gas" as a secondary effect - thereby igniting highly inflammable hydrogen via the exhaust valves. These hydrogen accumulations form so-called "nests" on the ceiling or the battery packs. From a certain concentration, a highly explosive hydrogen-oxygen atmosphere is formed: From now on, one electric spark is sufficient for a catastrophe.

In order to prevent this dangerous situation, there are special hydrogen sensors with the capability to trigger an alarm in good time. Secure your battery room with our new hydrogen sensor designed for batteries - a complete and compact monitoring system for H2 detection including visual display on the unit itself and an acoustic alarm buzzer as well as 7.5 meters / 295.28in. Connecting cable.

This device can be used to ensure compliance with the IEEE Std 484-2002, National Fire Protection Agency (NFPA) Article 64, and Uniform Building Code (UBC) sparkling wine 6400 standards for battery rooms.

The hydrogen sensor adapts flexibly to your system:
1.) As a standalone system
The potential-free contact output allows the sensor to be a stand-alone system and communicate with other systems. It can be transparently integrated into existing concepts as an additional protective measure. For example, a CON_AUX4 or CON_R_AUX4 can be used to establish communication with the CS141. This allows the user e.g. to configure triggering a fan / air conditioner to reduce the H2 concentration if necessary.





2.) With direct connection to a SENSORMANAGER

When a specific concentration is reached, potential-free contacts are switched. These contacts are monitored and evaluated directly by the manager. According to the configuration of manager the entire system will react to this alarm.

Input: 110V / 220V VAC and / or 12-48VDC (redundant), operation -30 ° C-90 ° C

Technical specifications

BACS ELS – Sensor system for wet cells





If the fill level drops drastically in the case of wet cells due to damage to the casing, a temperature increase including a complete function failure may happen. In worst case, the wet cell starts to burn. The regular monitoring of the filling levels in large installations is therefore indispensable, but also very time- and cost-intensive.

The new BACS ELS sensor offers a solution:
This BACS sensor is designed to detect and monitor the liquid level as well as the temperatures the whole wet cell, lead or NiCad batteries, equipped with a transparent or IR light-permeable housing. The sensor system is supported by external light compensation against external influences like sunlight or fluorescent tubes. Thus, it is reliable in industrial environments.

How BACS ELS works
The BACS ELS sensor uses several infrared proximity sensors, which can measure the liquid levels through the plastic housing transparent to low-wattage light beams and provide a very reliable signal. Therefore, the sensor is suitable for all wet cells with transparent or translucent plastics.
The assembly is carried out by means of a plastic frame which is bonded to the housing of the battery using a special adhesive for plastics.
After installing, the sensor provides several alarm states:
- "Good" (green)
- "Warning" (yellow)
- "Alarm" (red)
The BACS ELS can be installed as a "standalone" system without a BACS WEBMANAGER but also operate with the BACS bus system.

Detection of the filling level for wet cell batteries using
  transparent housing
- Different warning and alarm states to survey filling levels
- Works both: as a standalone system or like a BACS bus sensor
- High-precision temperature monitoring in stand-alone operation
- Additional display of temperatures in BACS bus mode
- Signaling of the status via LEDs as well as on the
  BACS website.

1.) ELS as standalone 
The ELS is connected to an Extended Distribution Box. The Extended Distribution Box provides the power supply for the sensor and ensures the communication to any higher-level warning systems
(ELS_EDB). The EDB coordinates connected sensors by reading measure values. At predefined values, the EDB closes alarm contacts to communicate with a system connected to it. The sensors itself provide an optical feedback to the monitored batteries via the LEDs to facilitate the search for a defective cell.





Order No.: BACS_ELS.

If the ELS is part of the BACS bus system, the measured data are transmitted to the BACS WEBMANAGER.
As a special feature, the ELS sensor and the BACS module simultaneously carry out their own temperature measurements. The BACS system gets temperature data from different measuring points of a monitored battery.
These measurement data can be displayed at the information screen of the WEBMANAGER, used to define alarm behavior and to configure BACS functions such as MODBUS; SNMP, e-mail, emailltrap, etc. to ensure more exact remote monitoring. Thanks to its LEDs, the ELS sensor can be additionally used for an optical aid on site. The alarm contacts are not required as the BACS WEBMANAGER manages all alarm threshold values and controls the necessary modules and functions accordingly.

- Detection of the filling level for wet cell batteries using
  transparent housing
- Different warning and alarm levels for filling level
  and temperature
- Usable as a flexible standalone system providing connections
  to higher-level alarm systems
- High Precision Temperature detection by innovative technology
Additional functions in conjunction with the BACS BUS:
- Second measuring point for decentralized temperature
- Signaling via BACS Manager and LEDs on site
















BACS current sensor with hinged sound sensor





The new BACS current sensor replaces the current sensors, which have been in use since 2006/2006. The more flexible design allows subsequent installation into existing battery systems. A hinge allows opening the upper ring to simplify inserting the power cables. In fact, retrofitting with this Hall sensor is quick and cost-effective: The fold-out ring makes the installation work easier and extensive conversions unnecessary.

Increased performance
In addition, these new devices cover higher measuring ranges, which has reduced the number of models in our product range into two designs: They cover a current range up to 500A or 2000A.

BACS externer Temperatursensor mit Faston-Stecker

(nur US-Markt)





For installations with US batteries, there is usually a Faston connection, which is used for performing a manual voltage measurement. With the installation of a BACS system, this connection is usually no longer used. Faston connections are not suitable for measuring the internal resistance of a battery. The BACS system also performs its own measurement of the internal resistance of the monitored battery in real time. As a result, measurement data are available and do not have to be collected manually.

Order No.: BACS_TS23FA



Why this Faston port is not useless:
Use it in conjunction with an external temperature sensor for BACS 3, which has a FASTON 6.3mm plug. The installation of external temperature sensors is easier than the use of adhesive pads to fit sensors to the batteries. The physical connection to the FASTON makes measurements more precise and the connection more lasting than installations with adhesives.

This product is identical to BACS_TS1L23 / BACS_TS1L90 but with a FASTON 6.3mm / 0.25in. Connector.

GSM and GSM_3G - Uplink







If system-critical or dangerous events occur in which competent coordinators and technicians have to intervene immediately even in the case of large network error, it is advisable to install independent communication paths.
A GSM modem provides this independent path:
The GSM modem connects via its own SIM card to its telecommunication provider and allows the CS141 to write an SMS for any event. As a result, technicians and coordinators remain reachable even in the case of a major disruption to emergency measures.

Order No.: GSM

The alternative to GSM: The 3G modem

While in Europe GSM is still an industrial standard and is actively operated by telecommunication companies. However, outside the EU zone some countries have already switched to the 3G standard and consistently shut down the GSM network.
Customers who need an independent uplink for emergency communications can use a 3G modem to send emergency information to the appropriate staff via SMS. In addition, the 3G modem is down-compliant to the GSM standard and can therefore be used worldwide.

The CS141 alarm buzzer







Optical alarms can be ignored easily during several simultaneously incidents - especially if a visual or acoustical alarm feedback is only partially visible due to the installation:  UPSs or accumulators are normally installed in fire-proof and rooms. An additional alarm is very useful to enhance warning capabilities.
The CS141 alarm has been reworked and replaced the previous model CS121_BUZ. The volume is 85dB of audio frequency (beep) and can be varied over the CS141. In this way, any events that are logged to the CS141 can be assigned to the alarm.
The reset is done via the web interface or a mute button. In addition, the alarm buzzer has relay contacts for notifying third parties.
The installation is carried out in closed rooms according to IP 22. The connection is made directly via the AUX port of the CS141. In the scope of delivery is a cable 5m / 196.85inch. contain.

BACnet Converter








Introduced in 1978, BACnet is a protocol standard, which is mainly used for building automation.
In fact, it is the only communication protocol standardized in accordance with DIN EN ISO 16484-5 and makes building automation interoperable. The only one condition is, the BIBBs must be defined to comply to this standard. By using this predefined standard, a user is able to make cost-effective changes and updates within his building automation without being bound to a specific manufacturer:
BACnet is designed to be used independently to any manufacturer.

The GENEREX product range now offers a BACnet converter for UPS products (CS121 / CS141) and BACS.
In principle, the converter requires a valid IP address inside the customer's network as well as a network connection to reach the CS121 / CS141 or the BACS system.  After it's successful connecting, the device will automatically convert measured values from Modbus-over-IP addresses or UPS and BACS alarms to BACnet.
The BACnet converter type BNC2 converts up to 2000 UPS measured values from Modbus / IP to BACnet. With BACS, the measured values of up to 330 BACS modules can be converted directly to BACnet. Furthermore, special BACnet address ranges can be supplied on request.
According to the usage, the power supply is ranged from 110V up to 230V.
