Infrared Photocell Beam Sensor Pair – Gate & Door Security Alarm
Asia-Teco Infrared Safety Beam Photocell Detector – 1 Pair
Protect your home, gate, door, or window with the Asia-Teco S1 Infrared Photocell Beam Detector. This wall-mounted single-beam sensor pair creates an invisible infrared barrier that instantly triggers your burglar alarm system the moment the beam is interrupted — giving you fast, reliable perimeter security for both indoor and outdoor applications.
Key Features
- Single Beam Infrared Technology – High anti-RFI/EMI capability keeps false alarms to a minimum, even in electrically noisy environments.
- Weather-Sealed Design – Sealed housing guards against rain, fog, dust, and insects. The built-in AGC (Automatic Gain Control) circuit automatically boosts detector sensitivity as conditions change.
- High-Power Transmitter – Sensitivity surplus of up to 90%, ensuring a strong, stable beam at all times.
- Energy-Efficient Receiver – High-performance infrared receiver tube with low-power processing technology for economical, always-on operation.
- Adjustable Beam Interruption Period – Fine-tune the trigger response time for maximum flexibility across different installation scenarios.
- Dry Relay Output – When the beam is interrupted, the relay outputs a voltage-free switch signal, making it compatible with virtually any alarm control panel (NO & NC modes supported).
- Anti-Jamming Optical Housing – Professional-grade housing minimises interference from ambient light and other infrared sources.

Frequently Asked Questions
Q: What is the maximum detection range of this infrared photocell beam sensor?
A: The Asia-Teco S1 infrared photocell detector covers up to 20 metres indoors and up to 10 metres outdoors. Outdoor range is reduced slightly to account for variable weather and ambient light conditions.
Q: Is this infrared beam sensor compatible with my existing burglar alarm control panel?
A: Yes. The sensor outputs a dry (voltage-free) relay signal in both Normally Open (NO) and Normally Closed (NC) modes, making it compatible with the vast majority of alarm control panels and gate controllers on the market.
Q: Can this sensor be used outdoors in wet or dusty conditions?
A: Absolutely. The sealed polycarbonate housing is designed to resist rain, fog, dust, and insects. The built-in AGC circuit automatically compensates for reduced sensitivity caused by environmental factors, keeping the detector reliable in challenging conditions.
Q: How is the Asia-Teco S1 photocell sensor installed?
A: The sensor is designed for wall-mounted installation. Mount the transmitter and receiver unit on opposing walls, posts, or surfaces so the infrared beam crosses the area you wish to protect. Secure each unit with the included hardware and connect the wiring to your alarm panel.
