Description
Photoelectric Beam Sensor 100m used in alarm systems. It will connect with any alarm system. Can also be used in automatic gate systems or garage door systems.
Environmental and performance features:
- Long-range detection: Provides up to 100m outdoor detection range.
- AGC circuit: Automatically adjusts sensitivity to compensate for gradual signal strength changes caused by weather conditions.
- Environmental protection: Includes features to protect against rain, dust, and insects. Many also have frost, snow, and dew protection or optional heating units for cold climates.
- Lightning and surge resistance: Protects the device from damage caused by power surges and lightning strikes.
- Visible light cutoff: Effectively blocks external visible light sources, like headlights, from causing false alarms.
- Adjustable interruption period: The time the beam must be broken to trigger an alarm can be adjusted, for example, to ignore jumping cats while still detecting human intruders.
Security and reliability features
- Dual beams: Requires two beams to be broken simultaneously to trigger an alarm, which significantly reduces false alarms caused by small objects, animals, or falling leaves.
- Double modulation: Uses a double-modulated pulse to distinguish the real signal from interference from sunlight or other artificial light sources.
- Synchronized pulse: Synchronizes the timing of the transmitter and receiver to improve reliability.
- Adjustable beam frequencies: Often offers multiple selectable beam frequencies to prevent interference between multiple sensors.
- Anti-tamper: May include a tamper output that triggers an alarm if the cover is detached.
Alignment and installation features
- Dual ring sight: Provides a clear view for easier beam alignment.
- Wireless alignment checker: Some models may include a wireless tool for easier and more accurate alignment.
