1. Introduction
Thank you for choosing the Denver ASA-50 Motion Detector. This device is designed to enhance the security of your premises by detecting movement and integrating seamlessly with the Denver HSA 120 Alarm System. This manual provides essential information for the proper installation, operation, and maintenance of your motion detector to ensure optimal performance and reliability.
2. Product Overview
The Denver ASA-50 is a passive infrared (PIR) motion detector, designed to sense changes in infrared radiation caused by moving objects, such as people. Its compact design and wireless capability make it suitable for various indoor security applications.
Figure 1: Front view of the Denver ASA-50 Motion Detector. This image shows the white rectangular casing with the PIR sensor lens prominently displayed on the front. A small indicator light is visible above the sensor lens.
Key Components:
- PIR Sensor Lens: Detects infrared changes caused by movement.
- LED Indicator: Provides status feedback (e.g., motion detected, low battery).
- Battery Compartment: Located on the rear, for AA batteries.
- Mounting Bracket: For wall installation.
3. Safety Information
- Do not expose the device to direct sunlight, high humidity, or extreme temperatures.
- Keep the device away from strong electromagnetic fields.
- Use only specified AA batteries. Do not mix old and new batteries or different types of batteries.
- Dispose of batteries according to local regulations.
- This device is for indoor use only.
4. Package Contents
- 1 x Denver ASA-50 Motion Detector
- Mounting Screws and Wall Plugs
- User Manual
Note: AA batteries are not included and must be purchased separately.
5. Setup
5.1 Battery Installation
- Open the battery compartment cover on the back of the motion detector.
- Insert the required AA batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
5.2 Mounting the Detector
The Denver ASA-50 is designed for wall mounting. Choose a location that provides optimal coverage of the area you wish to monitor, typically in a corner or on a wall facing the entry point.
- Select a suitable mounting height, usually between 2.0 to 2.4 meters (6.5 to 8 feet) from the floor.
- Use the mounting bracket as a template to mark the screw positions on the wall.
- Drill pilot holes and insert wall plugs if necessary.
- Secure the mounting bracket to the wall using the provided screws.
- Attach the motion detector to the mounting bracket, ensuring it clicks securely into place.
5.3 Pairing with HSA 120 Alarm System
To integrate the ASA-50 with your Denver HSA 120 Alarm System, follow the pairing instructions provided in your HSA 120 main unit manual. Typically, this involves putting the alarm system into 'learning' or 'pairing' mode and then activating the motion detector (e.g., by pressing a test button or triggering motion) to register it with the system.
6. Operating Instructions
Once installed and paired, the Denver ASA-50 Motion Detector operates automatically. When the HSA 120 Alarm System is armed, the motion detector will monitor its detection area for movement.
- Motion Detection: Upon detecting movement within its 12-meter range, the detector will transmit a signal to the HSA 120 Alarm System.
- LED Indicator: The LED indicator typically flashes briefly when motion is detected. It may also indicate low battery status (refer to HSA 120 manual for specific LED patterns).
- Detection Range: The detector has a maximum range of 12 meters. Ensure there are no obstructions blocking the sensor's field of view.
7. Maintenance
7.1 Cleaning
To maintain optimal performance, periodically clean the sensor lens and the device casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
7.2 Battery Replacement
The typical battery life is approximately 0.5 years (6 months). When the batteries are low, the HSA 120 Alarm System will usually indicate a low battery warning for the ASA-50. Replace all AA batteries simultaneously to ensure consistent performance.
- Disarm your alarm system before replacing batteries.
- Open the battery compartment cover.
- Remove the old batteries and dispose of them properly.
- Insert new AA batteries, observing correct polarity.
- Close the battery compartment cover.
- Test the detector to ensure it is functioning correctly and communicating with the alarm system.
8. Troubleshooting
- Detector not responding: Check battery installation and ensure batteries are fresh. Verify the detector is properly paired with the HSA 120 system.
- False alarms: Ensure the detector is not facing direct sunlight, heat sources, or moving objects like curtains or pets. Adjust mounting location if necessary.
- Limited detection range: Check for obstructions in the sensor's field of view. Ensure the mounting height is appropriate.
- Low battery warning: Replace batteries as described in Section 7.2.
