Battery Operated Carbon Monoxide Detector For Home Security Product Description
1. Brief introduction
KD-122LA Wireless Interconnected Fire Detecting Alarm is a photoelectric smoke alarm with low power consumption. Internal precise analog circuit, digital circuit and wireless transmission circuit make the detection work more stable and reliable. It has wireless interconnection function, which means when one unit makes alarm, other interconnected units within the interlink range will alarm at the same time. This product has small volume and the built-in large-capacity battery can provide service life of 10 years.
2. Product characteristics Photoelectric smoke detection Reliable performance and less nuisance alarms Precise analog circuit and digital circuit Low power consumption Small size Portable Interlink range >100m (RF868MHz free field) 3. Technical parameters
| Technical parameters | Smoke detection |
| Voltage | DC3V(built-in CP605050) |
| Low-voltage inspection | 2.2V |
| Current | Alarm current | Quiescent current |
| ≤120mA | ≤2uA |
| Status display | Normal smoke detection | LED (red) flashes once about every 344 seconds, no alarm sound |
| Smoke detection or key test | LED (red) flashes and continuous alarm is given |
| Low sensitivity detection (silent mode) | LED (red) flashes every 10 seconds, no alarm sound, automatically cancel low sensitivity detection about 9 minutes later |
| Alarm memory | LED (green) flashes 3 times about every 43 seconds, and stops 24 hours later. The first time you press test/mute button after alarm is made, the detector will hint by special alarm mode. |
| End of life | After power-up and work for 10 years, end-of-life warning will be made. The buzzer beeps 3 times every 43 seconds. |
| Low-voltage inspection | LED (red) flashes about every 344 seconds, beeps about every 43 seconds. |
| Alarm loudness | ≥85dB/3meters |
| Wireless interconnection | Radio frequency | 868MHz |
| Interlink range | ≥100m (open field) |
| Interconnection / learn indication | Red LED being steady on means the product needs to learn. Red LED flashing means signal transmitting. Green LED being steady on means the product is ready to send identification code. Green LED flashing means the unit has received wireless signal. |
