A GSM modem provides the notification or rather forwarding of the UPS events/alarms via
SMS. Please take a look into chapter 6.5 for further information.
SiteManager 2, SiteManager 2/v3
The selection of SiteManager 2, SiteManager 2/v3 enables the communication between the
CS121 and the SiteManager. The SiteManager is a professional facility management device,
which provides 8 configurable analog inputs, 8 digital inputs and 8 switchable relay contacts.
Please take a look into the SiteManager II user manual for further information.
SiteMonitor 2
The COM2 selection SiteMonitor 2 enables the communication between the CS121 and the
SiteMonitor 2. The SiteMonitor 2 is a professional facility management device, which provides
64 digital inputs for several contact detectors.
SM_T_COM
The SM_T_COM is a temperature sensor for the CS121 and is used for the monitoring and
controlling of UPS rooms, server rooms etc.. Please take a look into chapter 6.2 for further
information.
SM_T_H_COM
The SM_T_H_COM is a temperature and humidity sensor for the CS121 and is used for the
monitoring and controlling of UPS rooms, server rooms etc.. Please take a look into the
SM_T_H_COM datasheet for further information.

AUX and SITESWITCH4 Settings
The AUX connection is an input/output port for connecting external contact devices such as
alarms or for connecting to an SS4AUX SiteSwitch power socket manager. The SS4
SiteSwitch is a standalone device with a built in CS121. The SiteSwitch SS4 AUX is an
inexpensive and practical extension to the CS121 adapters enabling the individual power
switching of up to four power sockets
– using the inbuilt AUX port (4 pins) of the CS121. By
entering the corresponding list number, the AUX ports are switched to output or input.
The AUX port can only read signals, if the port is switched to input. If switched to output the
AUX port can send signals to an optocoupler for example. (Refer to the circuit diagrams in the
appendix.) After a reboot, the state of the switches remains in the status previous to the
reboot.
The following describes the configuration of the AUX ports using the HTML interface. All of the
AUX ports 1
– 4 can be manually set to „Output“ so that in the event of an alarm, the CS121
can be preconfigured in the “Events” menu to switch the ports individually. When all ports are
set to “Output”, this is equivalent to activating the „SS4 Mode“. The SS4 mode is to be
activated when connecting a SITESWITCH4 to the AUX port of the CS121.
When the Output options are deactivated, the AUX ports act as inputs used for monitoring
signals such as input from alarm contacts. For example, while configuring port 2 as an input to
monitor an alarm, the CS121 can also be preconfigured to respond to the alarm signal from
port 2 to shut on or off a device connected to one of the other ports that has been set to
Output.
For example see also the settings in figure “HTTP - COM2 & AUX” above.
The OUTPUT setting is to be configured with a power-up sequence so that, for example the
fileserver on port 1 will be switched on upon Power up. In the Power up delay-fields the
number of seconds after a Power up in which a connected port device is to be switched on can
be entered. E.g. the setting 10 in the Power delay column will cause the switching on of the
fileserver on Port 1 to be delayed by 10 seconds after the Power up. Note that executing the
Save, Exit & Reboot does not cause a Power up, in order to cause a Power up the power
supply to the adapter must be interrupted. The differences between a Reboot and a Power up
become more noticeable when considering the AUX port contacts. During a Reboot the current
