SEMS (Server station environment monitor system) is a special system developed by the company for unattended BTS in the telecommunication department. This system enables functional units including Power Distribution, BTS environment monitor and BTS temperature control, etc. to integrate together. It is characterized with complete functions, reliable performance, and simple operation.
Have original concept of energy-saving design, the system can analysis an calculated the different temperature of indoor and outdoor, with Blue Jay’s optimized control logic to effectively control the air circulation and heat exchange with the outside environment through the computer. Avoid prolonged use of the air conditioning system, can significantly improve the maintenance intervals and reduce energy consumption.
Verify form actual usage applications, SEMS can reduce energy consumption by 30% in the spring, autumn and winter, the average annual energy consumption savings of 12 to 18%.
GSM modem used for send & receive control instruction, Small size can be easily install, usually sends SMS text messages to a pager or cell phone when a sensor goes out of range of a configurable threshold.
In order to avoid unknown personnel access the BTS room, we use 10 digital keypad switches. Can set 6 digital passwords, keypad linkage with the alarm system, 3 times input errors will trig alarm.
INFRARED MOTION DETECTOR
We suggest customer use indoor infrared detector, with 8 to 10 monitor can detect a 100 square meters room, to protect the expensive equipment. Infrared monitor have Ceiling type and Horizontal type for 360-degree detect.
DOOR CONTACT SENSOR
Magnetic electronic locks used in conjunction with the keyboard. when entering the correct password can open the door, if external force open the door, will triggering the alarm.
SMOKE DETECTION SENSOR
Photoelectric smoke detector can detect indoor smoke particles, provide the initial information to determine the fire status, we suggest 4~5 pcs per 100 square meters, and independent install above the major equipment.
LIQUID DETECTION SENSOR
Provide flooding warning, installed in the lowest location of the room, can detect 0.25cm depth flooding, send alarm information via RS485 or GSM modem.
TEMPERATURE, HUMIDITY & COMBINATION SENSOR
Provide indoor and outdoor temperature & humidity parameters, for air conditioning/heater control, work in extreme environments, with high precision. Maintenance interval of three or six months one time, that to ensure control effective.
