Monitor temperature, humidity, water leakage and more

CM9001-EMS is an advanced Environmental Monitoring System which monitors temperature, humidity, water leakage and other sensors.

It is specifically designed for unattended facilities like data centres, server rooms, wine chillers, telecom base stations, and pharmaceutical freezers.

About Cytech EMS


Notification of alarm is via dialout to a maximum of 16 phone numbers for Voice announcements or SMS messages, or via email to 4 recipients.

8 outputs on the system can be programmed to control equipment via relays or to send Infrared signals to control air conditioning systems.

CM9001-EMS is a modular system which allows easy expansion of functions, Input/Outputs, and external interfaces like Modbus, KNX and C-Bus, or RS232 and RS485 interfaces.


Up to 4 sensor values and setpoints can be monitored and controlled by any of a maximum of 15 KP04A keypads in the system.

The temperature or humidity and setpoints are shown on the keypad LCD. Changes to the setpoint can be enabled or disabled.

Keypad screen

Setpoints and their alarms may be disabled when necessary, for example when testing so that the sensors are only shown for monitoring purposes.

Keypad screen

When the sensor reading exceeds the setpoint, an Alarm for the relevent sensor is triggered, which then calls or sends SMS messages to the selected phone numbers for that alarm. The alarm will cause an audible siren sound on the keypad and optionally on an external Siren. The alarm siren may be disabled by entering a code on the keypad. The Event Log with a capacity of 600 events can keep the history of the sensor alarms with date/time stamps.


Setpoints, Hysteresis, Calibration, Scaling, Units, and Sensor Name for up to 32 sensors can be programmed using the Comfigurator software, to be displayed on the KP04A LCD keypads.
