5. Setup and Installation
5.1 Compatibility and Connection
The WOS501S siren is an accessory for your Daewoo alarm system (e.g., DAEWOO SA501 alarms). It does not operate independently. Ensure your Daewoo alarm system supports RF433 Mhz communication for proper pairing.
The siren communicates with your alarm system via RF433 Mhz radio frequency, ensuring secure data transmission. It can be installed at a maximum distance of 90 meters (in an open area) from your main alarm unit.
5.2 Mounting Location
Choose an outdoor location that receives ample sunlight for the solar panel to charge effectively. The siren is designed to withstand various weather conditions, so it does not require placement under a roof or shelter. It can be mounted on any type of wall.

5.3 Wall Mounting Steps
- Select Location: Identify a suitable outdoor wall location with good sun exposure and within 90 meters of your Daewoo alarm panel.
- Mark Drilling Points: Use the siren's mounting holes as a template to mark the drilling points on the wall.
- Drill Holes: Drill holes at the marked points using an appropriate drill bit for your wall type. Insert the wall plugs.
- Secure Siren: Align the siren with the drilled holes and secure it using the provided mounting screws. Ensure it is firmly attached.

5.4 Pairing with Daewoo Alarm System
Refer to your main Daewoo alarm system's user manual for specific instructions on how to add a new wireless siren. Generally, this involves putting the alarm panel into 'pairing mode' and then activating the siren (e.g., by pressing a pairing button inside the siren or triggering it) to establish the connection.
6. Operating Instructions
Once successfully paired with your Daewoo alarm system, the WOS501S siren will operate in conjunction with it.
- Alarm Activation: In the event of a breach detected by your Daewoo alarm system, the WOS501S outdoor siren will automatically activate. It will emit a loud 100 dB alert sound and a bright flashing light. This serves to alert the immediate vicinity and deter potential intruders.
- Disarming: When your main Daewoo alarm system is disarmed (e.g., via remote control or keypad), the outdoor siren will cease its alert.
7. Maintenance
- Solar Panel Cleaning: Periodically clean the solar panel surface with a soft, damp cloth to ensure optimal charging efficiency. Dust, dirt, or debris can reduce its performance.
- Battery Life: The wireless siren is charged by the sun. The internal Lithium Polymer battery can last for approximately one month without any activation if there is no sunlight. If activated twice a day, the battery can last for about 20 days without sunlight. Regular sun exposure will maintain the battery charge.
- Weather Resistance: The siren is specifically designed to withstand various weather conditions. No special shelter is required.

8. Troubleshooting
- Siren Not Activating:
- Ensure the siren is properly paired with your Daewoo alarm system. Refer to Section 5.4.
- Check the distance between the siren and the main alarm panel. It should be within 90 meters in an open area. Obstructions can reduce range.
- Verify that the main alarm system is functioning correctly and detecting breaches.
- Weak Siren Sound or Flash:
- The battery might be low. Ensure the solar panel receives sufficient sunlight for charging. Clean the solar panel if it's dirty.
- Allow several days of good sunlight for the battery to fully charge.
- Siren Not Charging:
- Ensure the solar panel is clean and free from obstructions (e.g., leaves, snow).
- Relocate the siren to an area with more direct sunlight exposure.
