How to Replace the Battery

1. Prep the System

Put your security system into Test Mode or notify your monitoring station to avoid triggering false alarms. Removing the cover will cause a tamper alert, which is completely normal.

2. Remove the Siren from the Wall

Locate the two slots or tabs at the bottom of the siren cover.

Insert a flathead screwdriver into these slots and gently pop the siren housing off its backplate.

3. Swap the Batteries

Disconnect the old battery packs from their connector plugs inside the siren.

Wait about 10 seconds before installing the new ones.

Plug in the two new battery packs using the wire connectors. Ensure the wires are seated neatly in the battery compartment to avoid them being pinched when closing the cover.

4. Close and Secure

Align the top of the cover with the backplate, then push the bottom end in until it clicks firmly into place.

5. Clear the Tamper Alert

Go to your system keypad or touchscreen.

Enter your User Code to clear the tamper alert/trouble condition and silence any beeping.

What You Will Need

You will need a replacement battery kit (often listed as DSC BATT-PGX901/X911), which contains two special 3.6V Lithium-thionyl chloride battery packs. You will also need a flathead screwdriver to release the casing.

Frequently Asked Questions

How do I know if my Wireless Indoor Siren is working?

You can usually confirm the siren is working when your system is tested by Grand Alarms or during a supported alarm event. Do not intentionally trigger your alarm without speaking to Grand Alarms first, especially if your system is monitored. If you are unsure whether the siren is working properly, contact Grand Alarms and we can help check the device status.

How do I test my Wireless Indoor Siren?

Contact Grand Alarms before testing your Wireless Indoor Siren. A technician or support representative can guide you through the proper test process and help prevent unnecessary alarm activity. If your system is monitored, testing should be done carefully so signals are handled properly.

How do I know if the siren battery is low?

Your Grand Alarms system may show a low battery alert when the Wireless Indoor Siren needs battery service. You may see a notification on the panel or receive an alert through the Grand Alarms Smart Home App, depending on your system setup. If you see a low battery message, contact Grand Alarms for support.

How can I stop the siren from sounding?

If the siren is sounding because of an alarm event, disarm your Grand Alarms security system using your panel, keypad, or Grand Alarms Smart Home App. The siren should stop once the system is properly disarmed and the event is cleared. If it continues sounding, contact Grand Alarms for support.

Why is my Wireless Indoor Siren beeping?

The Wireless Indoor Siren may beep for system activity such as entry delay, exit delay, or certain system alerts, depending on how your system is programmed. If the beeping is unexpected, check your alarm panel or Grand Alarms Smart Home App for alerts. Common causes include low battery, tamper alerts, or system trouble conditions.

How do I turn down the volume on the Wireless Indoor Siren?

The Wireless Indoor Siren is designed to provide a strong alarm alert, so volume adjustment may be limited or handled through system programming. Contact Grand Alarms if the siren is too loud for its location. A technician can review your setup and confirm what adjustment options are available.

Can I move the Wireless Indoor Siren to another room?

Do not move the Wireless Indoor Siren without contacting Grand Alarms first. The siren needs to maintain reliable wireless communication with your security system, and removing it from the wall may trigger a tamper alert. A technician can confirm whether the new location is suitable.

Where is the best place to install the Wireless Indoor Siren?

The best location depends on your property layout. Common locations include finished basements, second floor hallways, garage entry areas, home offices, workshops, and areas far from the main panel. Grand Alarms can recommend placement based on sound coverage, signal quality, and system design.

Does the Wireless Indoor Siren work during a power outage?

The Wireless Indoor Siren is battery powered, so it is designed to operate without being plugged into an outlet. Your overall system performance during a power outage depends on your alarm panel backup battery, system condition, and monitoring setup. If you have concerns, Grand Alarms can review your backup protection.

Can I add more than one Wireless Indoor Siren?

Yes, compatible systems can support multiple sirens. Some compatible systems can support up to 16 total sirens, depending on the alarm panel, system design, and installation requirements. Grand Alarms can confirm what is appropriate for your home or business.

What should I do if my Wireless Indoor Siren is not responding?

Check your alarm panel or Grand Alarms Smart Home App for trouble alerts, low battery messages, or tamper notifications. Do not remove or reset the siren without support. Contact Grand Alarms so we can help check the device status, signal condition, and next steps.
