Intelligent Photoelectric Smoke Fire Sensor Alarm Detector Warming Equipment for Home Security
$ 50.99
Feature:
- Built-in intelligent handler, using a unique detection algorithm to make sure product stability and reliability.
- When the smoke concentration around the detector exceeds the set alarm concentration value, the detector alarms and the indicator flashes.
- The product complies with the EU ROHS directive, has high sensitivity, can accurately detect smoke concentration and promptly alarm.
- It has excellent resistance to electric and magnetic field interference and current surge protection.
- Easy to install and does not need to be debugged, suitable for families, apartments, office buildings, warehouses, schools and factories.
Specification:
Condition: 100% Brand New
Item Type: Smoke Detector
Material: Plastic
Supply Voltage DC: 12V (9V-16V)
Quiescent Current: <8mA
Alarm Current: <40mA
Output Form: Relay Normally Open / Normally Close Output
Output Contact Capacity: 3A / 125VAC Or 3A / 28VDC

Operative Standard: GB4715-2005
Use and Operation:
- Power-On Self-Test: the two indicator lights flash just once after the power is turned on, and then enter the normal working state.
- Working State: the two indicator lights flash once every 321 seconds, and the detector is in normal monitoring state.
- Alarm Status: when the smoke concentration around the detector exceeds the set alarm concentration value, the detector will alarm, the two indicator lights will flash, and the relay will be on. When the alarm lasts for 601 seconds, the detector will stop the alarm and detect the smoke concentration at that time again for 101 seconds. If the smoke concentration in the air still exceeds the set alarm concentration value, the detector will alarm again; if the air When the medium smoke concentration is lower than the alarm concentration value, the detector will automatically return to the normal monitoring state.
- Test State: When in the working state, press the "test key", the two indicators flash, (the flashing returns to the normal monitoring state), the relay is on, and the detector is artificially placed in an alarm state.
Package List:
1 x Smoke Detector
1 x Instruction Manual
2 x Expansion Plug
4 x Screws
1 x Installation Buckle
Note:
- Do not install the detector in the occasion of strong air convection, and do not install the detector too close to the corner of the wall.
- Maintain dust and moisture resistance, and regularly clean the dust screen of the detector.
- The detector should be tested once a month, for example: artificially press the "test key" to make the detector enter the alarm state or conduct a smoke test.
