ST-710

Carbon monoxide alarm

 

   
   

Features

1.      Gas alarm meets UL 1484 standard; Carbon monoxide alarm meets the most recent UL 2034 standard.

 

2.      Built-in the high tech carbon monoxide sensor and the gas sensor, has the high sensitivity, the high stability, and the high gas selectivity’s characteristic, may precise detect the carbon monoxide and the gas concentration.

 

3.      With the advanced high tech microprocessor and the wisdom control, processing the precise computation of the carbon monoxide's concentration and through time, and have much intelligent control.

 

4.      Provide the test / silence button, besides internal self- diagnosis, under the stand-by status, may lightly press the test / silence button to test the alarm. This button also provides the specialist to test the system link when continuously presses the button for 8 seconds.

 

5.      Provide the power switch button, it automatically turn on when inserts the power source, when continuously press the button for 1 second, it will turn off, and has the key tone. This button provides the specialist to use; usually this product should setting for the turn on condition.

 

6.      Built-in the high efficiency wide-range Switching Power Supply, suitable to the universal voltage.

CO alarm is the last defense line of prevents the carbon monoxide poisoning. UL 2034 (Single and Multiple Station Carbon Monoxide Alarms) has the most detailed standard. The unit conforms to the most recent UL 2034 standard.
 
   
 

The matches valves

Solenoid valve (Model: V15 or V20)

  During normal status, the valve is no power consumption, energy saving and high safety.

  The pipeline bursts, boils the overflow, blows out ... and so on cause which the gas leaks, gas alarm output the 12V pulse signal to the valve to interrupt gas.

  The pull rod has the dustproof and waterproof cover. Meet IP-54.

  Could use the manual control to opens or closes the valve.

  Suits to the pipe size: 1/2" or 3/4" (V15 for 1/2”, V20 for 3/4”)

  Working pressure: 500mBAR

  Must conjunction the gas alarm or related equipment that provide the signal.

  Corresponding alarm series: ST-700AE, ST-710AE, and ST-720AE…(Refer to the Selection guide)

 

Mechanical valve (Model: MV-20N)

  During normal status, the valve is no power consumption. Suit for any working pressure.

  When the gas concentration achieved the threshold, the alarm provides DC12V to the mechanical valve, automatically turns off the gas, guarantees the security.

  With manual shut-off and reset button.

  Directly installs on the ball valve. Unnecessary to cut off the gas pipeline, installs conveniently.

  The substitution product of the solenoid valve, must conjunction the gas alarm or related equipment that provide the signal.

  Corresponding alarm series: ST-700AM, ST-710AM, and ST-720AM…

 

 

For single station useIf the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
