Product SKU: S9001
Product Overview
The DAS S9001 Internal Piezo Screamer is a hardwired indoor alarm sounder designed to provide strong audible warning for compatible intrusion alarm systems. It uses an electronic driver with a 12VDC rated input, ABS plastic housing and a white internal enclosure measuring 115(W) x 160(H) x 40(D)mm. With a listed sound pressure level of 105–115dB at 1m and current consumption ranging from 100–250mA depending on operating conditions, the S9001 is suitable for homes, shops, offices, garages, staff areas, stockrooms, workshops and light commercial premises where a dedicated internal screamer is required. It also includes a tamper switch loop using two yellow wires, making it more suitable for alarm installations where internal sounder tamper monitoring is required.
Key Capabilities
High Output Internal Screamer
The S9001 provides a strong internal piezo alarm tone rated between 105–115dB at 1m, helping alert occupants and deter intruders during alarm activation.
Electronic Driver Type
The electronic driver design is intended for compatible hardwired alarm systems requiring a dedicated internal piezo sounder.
12VDC Alarm Integration
The screamer is rated for 12VDC and supports a 6–12VDC voltage range, making it suitable for many compatible low-voltage alarm panel sounder outputs.
Tamper Switch Loop
Two yellow wires provide the tamper switch loop, allowing compatible systems to monitor the internal sounder for interference when connected correctly.
ABS Plastic Housing
The white ABS plastic enclosure provides a practical indoor finish for alarm sounder installations in residential and light commercial spaces.
Clear Wire Identification
Red and black power wires support straightforward connection, while the two yellow wires are used for the tamper switch loop.
Best For
- Home Alarm Systems: Suitable for internal alarm warning in hallways, garages, utility rooms and living areas.
- Small Business Security: A practical option for shops, offices, clinics, salons and other light commercial premises.
- Secondary Internal Sounding: Useful alongside an external siren or siren/strobe where extra internal alarm sound is required.
- Tamper-Monitored Sounder Installations: Suitable where the internal screamer should be connected with a tamper switch loop.
- Alarm Replacement Jobs: Useful when replacing an older internal piezo screamer in a compatible hardwired alarm system.
Why Choose the S9001
Choose the DAS S9001 when the alarm installation needs a dedicated internal piezo screamer with strong sound output, 12VDC operation and tamper loop wiring. Its 105–115dB output range makes it suitable for indoor alarm warning, while the ABS plastic housing and clear wire connections support straightforward installation in compatible alarm systems. Compared with a basic internal sounder without tamper wiring, the S9001 gives installers a more complete internal screamer option for alarm systems that need tamper monitoring. This model, supplied by Security Wholesalers, is a practical choice for residential and light commercial security installations requiring a high-output internal sounder.
Buyer Decision Tips
Buyer Tip: Confirm the alarm panel output voltage and current capacity before installation. The S9001 is rated for 12VDC operation, supports a 6–12VDC voltage range and can draw 100–250mA depending on operating conditions.
Buyer Tip: Wire the tamper loop correctly if tamper monitoring is required. The red and black wires are for power, while the two yellow wires are for the tamper switch loop.

Choosing the Right Model
- Choose this model if: You need a DAS internal piezo screamer with ABS housing, 12VDC operation, high sound output and tamper switch loop wiring.
- Choose a combo siren/strobe if: The installation also requires visual alarm indication or a combined audible and strobe warning device.
- Choose an external siren/strobe if: The installation requires outdoor warning presence, weatherproof housing or external visual deterrence.
- Check before installation: Confirm output voltage, current capacity, polarity, tamper loop wiring, mounting position, cable route and total sounder load.
FAQs
- What is the DAS S9001 used for?
The DAS S9001 is used as an internal piezo screamer for compatible hardwired alarm systems. It provides a loud internal alarm tone for homes, offices, shops, garages, staff areas and other indoor spaces where additional audible alarm warning is required. - What voltage does the S9001 require?
The S9001 is rated for 12VDC operation and supports a 6–12VDC voltage range. The installer should confirm that the alarm panel or auxiliary output is suitable before connection, especially if multiple internal sounders are being powered from the same output. - How loud is the S9001?
The S9001 is listed with a sound pressure level of 105–115dB at 1m, with another listed range of 105–110dB. Actual perceived loudness depends on mounting position, room size, doors, walls, building layout and background noise. - Does the S9001 include tamper wiring?
Yes. The S9001 includes two yellow wires for the tamper switch loop, with the tamper switch loop listed at 2Ω maximum. The tamper loop should be connected according to the alarm panel’s zone or tamper monitoring requirements. - How is the S9001 wired?
The red wire is used for power positive and the black wire is used for power negative. The two yellow wires are used for the tamper switch loop. Wiring should be completed by a qualified installer according to the alarm panel design and site requirements. - Is the S9001 suitable for outdoor installation?
No. The S9001 is an internal piezo screamer and should be installed indoors or in a protected internal location. If the installation requires external alarm warning, use a weatherproof external siren/strobe designed for outdoor mounting. - What are the dimensions of the S9001?
The S9001 measures 115(W) x 160(H) x 40(D)mm and uses a white ABS plastic housing. This size makes it suitable for wall mounting in internal areas where a clearly audible alarm sounder is required. - What should I check before buying the S9001?
Before buying the S9001, confirm that your alarm system supports a 12VDC internal sounder, the current draw is suitable, and the tamper loop wiring can be connected if required. This model is available through Security Wholesalers for compatible hardwired alarm installations needing a high-output internal piezo screamer.
