Free sample for Fire Detector For Subway Station - NMS2001-I Control Unit – Anbesec

NMS2001-I is applied to detect the change of sensing cable’s temperature, and negotiate with the fire alarm control panel.

NMS2001-I can monitor the fire alarm , open circuit and short circuit of the detected area constantly and  continuously, and indicate all the data on the  light indicator. NMS2001-I shall be reset after power-off and on, due to its function of fire alarm locking. Correspondingly, the function of fault alarm can be reset automatically after fault clearance, NMS2001-I is powered by DC24V, so please pay attention to power capacity and power cord.

Features of NMS2001-I

♦ Plastic shell: Chemical resistance, aging resistance and shocking resistance;

♦ Simulation test of fire alarm or fault alarm can be conducted. Friendly operation

♦ IP rating: IP66

♦ With LCD, Various alarming information could be shown

♦ The detector has high ability of interruption resistance adopting fine grounding measurement, isolation test and software interruption resistance technique. It is able to apply in places with high electromagnetic field interruption.

Usage and operation of NMS2001-I

After the connection and installation, turn on the control unit, then the green indicator light blinks for one minute. Followed that, the detector could go normal state of monitoring, the green indicator light is on constantly. The operation and set could be handled on the LCD screen and buttons.

(1) Operation and set displaying

Displaying of normal running :

Displaying after pressing“Fun” :

Press “△” and “▽” to choose the operation, then press “OK” for confirmation into the menu, press “C” for returning the previous menu.

The menu design ofNMS2001-I is shown as following:

Press “△” and “▽” to change the current data in the secondary interface“1.Alarm Temp”, “2.Ambient Temp”, “3.Using Length”;

Press “C” to the previous set data, and “OK” to the next data；press “OK” at the end of current data for confirming the set and back to the previous menu, press “C” at the beginning of the current data to cancel the set and back to the previous menu.

(1) Set of fire alarm temperature

The fire alarm temperature could be set from 70℃ to 140℃, and the default setting of pre-alarm temperature is 10℃ lower than the fire alarm temperature.

(2) Set of ambient temperature

The maximum ambient temperature of detector could be set from 25℃ to 50℃, it may help the detector to adjust the adaptation to the working environment.

(3) Set of working length

The length of the sensing cable could be set from 50m to 500m.

(4) Fire test, fault test

The connectivity of the system could be tested in the menu of fire test and fault test.

(5) AD monitor

This menu is designed for AD check.

The alarm temperature is in proportion to the ambient temperature and the using length theoretically, set the alarm temperature, the ambient temperature and the using length rationally, so that the stability and the reliability could be improved.
