## Summary description

Atlo ATLO-AH-SL523 is a motion detector equipped with a PIR sensor and an integrated alarm siren. Designed to detect infrared motion changes, it provides local audible alerting via the built-in siren. Suitable for basic intruder detection and perimeter monitoring in homes, offices or small commercial spaces where a combined motion sensor and alarm output is required.

## Long description

Atlo ATLO-AH-SL523 is a compact motion detector combining a passive infrared (PIR) sensor with an integrated alarm siren. The device senses changes in infrared radiation caused by moving people or animals and triggers a built-in audible siren to provide immediate local alerting. Designed for straightforward installation, this combined motion sensor and siren is intended for basic intruder detection and perimeter monitoring in homes, offices and small commercial spaces where an on-site alarm tone is sufficient for initial deterrence or notification.
Advantages
The integrated siren eliminates the need for a separate alarm sounder, reducing cabling and installation complexity. The PIR sensor offers reliable detection of human movement while minimizing false alarms from static heat sources. Its compact housing and simple mounting options allow flexible placement on walls or corners. The unit is suitable for standalone use or as part of a broader security setup where a local audible alert is required.
Suitable for
 Basic intruder detection in residential rooms and entrances
 Perimeter monitoring of small offices and retail spaces
 Temporary or rental properties requiring minimal wiring
 Auxiliary local alarm signaling where visual confirmation or rapid response is available
Key specifications
 Detection technology: passive infrared (PIR) motion sensing
 Integrated audible output: built-in siren for local alerts
 Coverage: designed for typical indoor room and corridor monitoring (manufacturer-recommended placement)
 Mounting: wall or corner mounting with compact housing
 Power: low-voltage power supply or battery operation depending on installation (refer to installation manual)
How to use
Install the detector at the recommended height and orientation to cover the intended area, avoiding direct exposure to heating vents or windows that may cause false triggers. Connect the unit to the power source and any alarm control panel or leave as standalone according to the installation method. After powering the device, allow the PIR sensor warm-up time as specified in the manual before testing. Perform a walk-test to confirm coverage and adjust positioning to reduce blind spots. Follow local electrical and safety regulations during installation.
Usage recommendations
Place the detector at a height and angle that maximizes cross-traffic detection rather than directly facing expected motion routes. Regularly test the siren and sensor functionality, and keep the device free from dust and obstructions for reliable operation.
