- Internal Alarm Warning: The 110dB high tone provides strong audible alarm warning inside the protected premises.
- Entry and Exit Notification: The 90dB low tone is ideal for entry and exit tone notification where a lower sound level is preferred.
- Tamper-Monitored Sites: Useful where the internal sounder must include wall and cover tamper protection.
- Professional Internal Fit-Outs: Practical for offices, retail stores, clinics, service areas, warehouses, corridors and commercial alarm projects.
Why Choose the SOINT2/WH/HI-LO
Choose the CQR SOINT2/WH/HI-LO when the installation requires a Grade 3 internal sounder with selectable high and low sound output. The high 110dB tone is suited to internal alarm activation, while the lower 90dB tone is useful for entry and exit notification where a less intense local tone is required. Its wall and cover tamper protection, independent LED status notification, Mylar cone sounder type and low-profile white housing make it suitable for professional alarm fit-outs where supervision and clean presentation are both important. This model, supplied by Security Wholesalers, is a practical option for compatible 12VDC intruder alarm systems requiring a white hi-lo internal sounder.
Buyer Decision Tips
Buyer Tip: Confirm the alarm system requires a Grade 3 internal sounder and can support the 12VDC operating requirement and 300mA sound-only current draw.
Buyer Tip: Use the 110dB high tone for alarm warning and the lower 90dB tone for entry and exit notification where a less intense sound is preferred.

Choosing the Right Model
- Choose this model if: You need a white Grade 3 internal sounder with selectable 110dB high tone, 90dB low tone, LED status notification and wall/cover tamper.
- Choose a basic internal screamer if: The installation only needs a simple internal alarm sounder without Grade 3 requirements, selectable hi-lo output or tamper supervision.
- Choose an external siren/strobe if: The site requires outdoor warning presence, weatherproof housing or visual deterrence outside the protected premises.
- Choose a passive speaker if: The alarm panel provides a siren driver output and the installation requires a passive speaker rather than an electronically driven sounder.
- Check before installation: Confirm Grade 3 requirements, 12VDC compatibility, 300mA current capacity, tamper wiring, LED status wiring, mounting position and required sound level.
FAQs
- What is the CQR SOINT2/WH/HI-LO used for?
The CQR SOINT2/WH/HI-LO is used as a Grade 3 internal sounder for compatible intruder alarm systems. It provides selectable high and low sound outputs, making it useful for both internal alarm warning and lower-level entry or exit tone notification. - How loud is the SOINT2/WH/HI-LO?
The sounder offers selectable output with a high alarm tone rated at 110dB and a low alarm tone rated at 90dB. The higher tone is suited to alarm activation, while the lower tone is ideal for entry and exit notification where a less intense sound is preferred. - Is this sounder Grade 3?
Yes. The SOINT2/WH/HI-LO is listed as EN50131-4 Grade 3. The installer should still confirm that the full alarm system design, panel programming, tamper wiring and installation method meet the site’s required grading and compliance expectations. - Does it have tamper protection?
Yes. The CQR SOINT2/WH/HI-LO includes wall and cover tamper protection. This allows a compatible alarm system to monitor the internal sounder for removal, cover opening or interference, depending on how the tamper circuit is connected. - Can it be used for entry and exit tones?
Yes. The lower 90dB selectable tone is ideal for entry and exit tone notification. This allows the sounder to provide a more suitable notification tone during normal entry or exit periods without using the full 110dB alarm tone. - Does it include LED status notification?
Yes. The SOINT2/WH/HI-LO includes independent LED status notification with a white LED cover. The final indication behaviour depends on how the installer connects and configures the device with the compatible alarm system. - Is this an internal or external sounder?
This model is an internal sounder with low-profile plastic housing and an IP4X rating. If the installation requires outdoor warning, weatherproof construction, external strobe indication or a visible deterrent box, choose a suitable external siren or siren/strobe instead. - What should I check before buying the SOINT2/WH/HI-LO?
Before buying the SOINT2/WH/HI-LO, confirm that your alarm system requires a Grade 3 internal sounder, supports 12VDC operation, can provide 300mA for sound-only operation, and can use the tamper and LED status functions as intended. This model is available through Security Wholesalers for compatible professional alarm installations.
