Introduction
4-Wire smoke alarm with relay output is common used for industrial control equipment, power cubicle, charging pile, alarm bell etc fire warning system. This smoke alarm has the characteristics of high sensitivity, stability and reliability, small power consumption and durability. Easy to install.
Parameters | Product Name | smoke detector with relay output | Rated operational voltage | DC12~24V |
| Sound pressure level | ≥65db | Static current | ≤300uA |
| Alarm current | ≤90Ma | Work temperature | -10°C~+50°C |
| Output | Sound&light alarm, relay output | Humidity | ≤95%. |
| Product standard | CE | Dimension | Φ105mm,H50mm |
Functions Work : Under normal circumstances, the indicator of the detector will flash about every 8 seconds. When the smoke concentration reaches or exceeds the alarm value, the red LED light of the detector remains bright, makes a sound, and starts the relay output.
When the smoke concentration in the environment returns to normal state, the detector automatically returns to normal state ( Alarm can automatically restore the state ).
Installation
The mounting hole size of the detector base is 49mm – 64.2mm. During installation,
two installation holes with a diameter of 5 mm were punched at a suitable position on the ceiling.
Smoke detectors are not suitable for use in :
A. Places where smoke is normally held ;
B. where there are large dust, water mist, steam, oil mist pollution and corrosive gas ;
C. ventilation speed is greater than 5m / s.
