Smoke Detector Wired Satel TSD-1

The Satel TSD-1 is a wired smoke detector designed to detect early stages of a developing fire by combining a photoelectric sensor for visible smoke with a rate-of-rise temperature sensor. Powered from a 12 V DC source, the detector has a compact, low-profile housing with a diameter of 10.8 cm, a height of 61 mm and a weight of 164 g. A specially shaped measuring chamber offers high sensitivity and omni-directional detection, while a Hexamesh stainless steel filter protects the sensing chamber against contamination and small insects. Configuration is performed with DIP switches and the unit includes built-in parametric end-of-line resistors to simplify connection to a wide range of alarm control panels.

Advantages

The TSD-1 combines dual sensing technologies to provide reliable early warning: a photoelectric element for visible smoke and a rate-of-rise thermal sensor to detect rapid temperature increases. Its compact dimensions and light weight make installation unobtrusive in both residential and commercial environments. The Hexamesh stainless steel filter reduces false triggers from dust and insects while preserving sensor sensitivity. DIP-switch configuration and integrated end-of-line resistors streamline commissioning and compatibility with many 12 V control panels.

Suitable for

• Residential rooms and apartments where unobtrusive, wired smoke detection is required
• Offices and commercial premises with central alarm control panels
• Shared corridors and common areas in multi-unit buildings
• Industrial or utility spaces where early detection of smoke and rapid temperature rise is needed

How to use

Mount the Satel TSD-1 on the ceiling or high on a wall according to local installation standards and the control panel manufacturer’s wiring diagrams. Connect the detector to a compatible 12 V DC alarm control panel, observing correct polarity and using the built-in end-of-line resistors if required by the panel. Adjust detector settings with the DIP switches to match the system configuration and zoning requirements. After wiring and configuration, test the detector function using approved test methods and verify communication with the alarm control panel.

Usage recommendations

Install the detector in locations free from heavy dust, strong drafts or steam sources that could cause false alarms. Schedule regular visual inspections and functional tests, and follow the control panel manufacturer’s maintenance intervals. Replace the detector if it becomes physically damaged or fails performance tests; consult local fire safety codes for recommended placement and testing frequency.
