SD-218
Sentek
Stand-alone Detectors
SD218 series photoelectric smoke detectors are designed in accordance with EN14604:2005 and manufactured under the best quality control. The SD218 series alarm are adopted the reliability UL-certificated infrared components. The SD218 series alarm also act as a smoke sensor and/or a 135 o F heat detector at the same location.
• Photoelectric sensing technology
• Sleek low-profile housing design
• Low-sensitivity warning
• Low-battery warning
• Battery case at the back of a detector for easy removal of a battery
• SMD circuit board design-satisfactory quality and reliability guaranteed
• Test button verifies battery and alarm operation
• Sounding a loud alarm signal of exceeding 85db in alarm mode
• Easy installation and maintenance
• Five-year limited warranty
