The ambient temperatures should be monitored when operating a UPS solution, regardless of where the batteries are located because operating them outside the specifications can permanently damage the system and the batteries and, in extreme cases, even result in fires. With the temperature sensor, you can monitor the facility in real time and receive a warning, in due time, if the operational temperatures are concerning.

Both measurement results can be independently combined with other sensors via a sensor matrix to automate a variety of responses to the environment.

The SM_II_T_H offers temperature and humidity, but requires 2 ports.

Access control systems and burglary protection

The UPS solution is a particularly important target within infrastructures because they secure the operation of critical systems until other emergency systems can take effect. GENEREX therefore offers active access control systems to respond quickly to unauthorized entry:

Glass breakage detector

Ord. No.: SM_II_GLAS

The SM_II_GLAS glass breakage detector is a fast and efficient way of ensuring the security of glazed surfaces and immediately outputting a digital alarm in the event of cracks.

Gas and hazardous substances sensors

Based on production conditions, toxic, fatal or highly explosive gas mixtures may develop. Gas sensors are often the only option for detecting these sometimes odorless and colorless hazards in time and taking automatic countermeasures.

Smoke Detector

Ord. No.: SM_II_SD1

When fire protection regulations require, these sensors must secure facilities or flammable areas. Even without this statutory requirement, this sensor is recommended because the earlier the warning, the faster suitable measures can be taken in response.

The smoke detector reliably detects acute smoke development. It can also be coupled to the measurement results of other sensors and contacts which makes this sensor very flexible.

Hydrogen Sensor

Ord. No.: SM_H2_LC

Hydrogen typically forms as a by-product of the charging process of batteries and is released into the environment via valves or open cases. Since it is much lighter than the surrounding air, it rises and collects on overhangs, in shelves, niches, ceiling areas, etc. As soon as the hydrogen concentration reaches about 4%, an unstable and highly flammable gas mixture will be formed up. Since hydrogen itself is odorless and colorless, you need specialized sensors like the SM_H2_LC require hydrogen sensors with which hydrogen can be detected at an early stage. The hydrogen sensor SM_H2_LC has a two-stage warning system in which the warning levels are triggered independently of one another. When used with the SITEMANAGER 6, the SM_H2_LC is placed directly on the digital inputs in order to receive a corresponding warning signal.

Power Supply Voltage: 9 – 112V DC (stabilized)
Current Consumption: ca. 300mA max.
operating temperatur: 0 - 40 C
measurement accuracy: +/- 20% under calibration condotions (20 C, 1013 hPa, hum. 65%)
Max. measurable instantaneous hydrogen concentration: 100% LEL (<1min/30min)

Sensors for the current flow

A UPS solutions depends on the quality of the batteries. They are subject to a natural aging process over time so the whole system’s performance decreases. The internal quality of the discharging/charging currents in the UPS solution can be monitored using the GENEREX current sensors.
