Introduction to the AX Pro Wireless Internal Sounder
AX Pro Wireless Internal Sounder (DS-PS1-I-WE(B) — Red)is an indoor two-way wireless siren and strobe designed for AX Pro security systems. Built for installers and end-users who need a reliable audible and visual alarm accessory, this compact unit combines a loud internal buzzer (approximately 90–110 dB), selectable alarm tones (intrusion, panic, fire), front and rear tamper detection, and a red/blue strobe LED for immediate visual signalling. Communicating over 868 MHz Tri‑X two‑way protocol with frequency hopping and AES‑128 encryption, it offers secure, long-range wireless signalling suitable for both domestic and light commercial environments. With a suggested retail price of 74.99 (cost price 48.44), the DS-PS1-I-WE(B) is positioned as a practical, installer-friendly accessory for AX Pro wireless systems.
- 868 MHz Tri‑X two-way wireless with frequency hopping for reliable links and reduced interference risk.
- AES‑128 RF encryption to protect communication between the sounder and control panel.
- Selectable alarm sounds: intrusion, panic, fire.
- Adjustable maximum sound duration (up to 900 seconds per activation) to tailor response behaviour.
- Integrated red/blue strobe LED for visual alerting in noisy or sensitive areas.
- Front and rear tamper detection to protect against removal or panel interference.
- Battery powered (3 × CR123A) with a typical lifespan around 3 years under typical polling and trigger patterns.
- Compact PC+ABS housing (88 × 88 × 32 mm) for unobtrusive indoor wall mounting.
Detailed specifications and benefits
Knowing the technical specifications is essential when selecting a sounder for an intruder alarm installation. Below is a breakdown of the DS-PS1-I-WE(B) specifications and the practical benefits they deliver.
- Model:DS-PS1-I-WE(B) (Red LED). Compact profile suitable for indoor placement where visibility and audibility are required without bulk.
- Product type:Wireless internal sounder (AX Pro accessory). Designed to integrate seamlessly with AX Pro panels and the Hik-Connect ecosystem for remote configuration.
- Alarm sounds:Intrusion, panic, fire (selectable). Flexibility to configure the tone to match the type of alarm or the site policy reduces confusion and ensures appropriate action.
- Max sound duration:Up to 900 s (configurable). Useful where prolonged alarm signaling is required or where local regulations demand extended activation times.
- Certification/grade:EN 50131 referenced (Grade 2). Documentation references this standard; installers should follow local regulations and test installations accordingly.
- RF frequency:868 MHz (2GFSK). A commonly used frequency band in many regions that balances range and power consumption.
- Protocol:Tri‑X (two‑way, frequency hopping). Two-way communication allows supervision and acknowledgment between device and panel; frequency hopping improves reliability in crowded RF environments.
- RF security:AES‑128 encryption. Industry-standard encryption to reduce risk of spoofing or interception.
- Range (open area):Up to 1.6 km (line‑of‑sight). Real-world range will be lower in buildings but this indicates strong link capability for larger sites.
- Sound level:Approx. 90–110 dB. Loud enough to alert occupants and act as deterrent in many scenarios.
- Battery type:3 × CR123A. Readily available batteries that are easy to replace during maintenance.
- Battery life:Typical ≈ 3 years under typical polling/trigger patterns. Long-life operation reduces maintenance visits and operational costs.
- Dimensions & weight:88 × 88 × 32 mm, approx. 169.5 g. Small, light and discreet — suitable for apartments, offices and retail premises.
- Material:PC + ABS housing. Durable and suitable for indoor use.
- Operating environment:−10 °C to +55 °C; 10% to 90% non-condensing humidity. Meets the needs of most indoor installations.
- Secure two-way RF with AES‑128 reduces false or malicious activations and allows supervision messages for healthier system uptime.
- High sound levels combined with a strobe LED deliver both audible and visual deterrence, useful in busy or noisy environments and for occupants with hearing impairments.
- Battery operation simplifies installation where running mains cabling is impractical or costly and enables installation in rented properties where surface-mounted or wireless devices are preferred.
- Configurable sound duration and selectable tones give installers the flexibility to meet site-specific needs and local regulations.
Use cases and scenarios where the product excels
The DS-PS1-I-WE(B) suits a range of domestic and commercial scenarios. Its compact size, battery operation and strong RF design make it particularly useful in the following situations:
- Quick-to-deploy audible/visual alert without intrusive wiring works well in rented apartments or heritage properties where cable routing is limited.
- Selectable tones allow homeowners to differentiate between fire and intrusion alerts, so occupants can respond appropriately.
- Internal sounder provides immediate on-site alerting to staff and customers while a control panel or monitoring station handles notification and response.
- Discrete housing blends with interiors while providing a visible and audible deterrent to would-be intruders.
- Use as additional internal sounders in outbuildings, garages or remote rooms where the main panel’s siren may be less audible.
- Long line-of-sight RF range supports placement further from the panel in large properties, factories or warehouses (subject to site testing).
Comparisons with similar products in the market
When comparing the AX Pro DS-PS1-I-WE(B) to other internal wireless sounders, consider these key differentiators:
- Two-way vs one-way RF:Two-way devices (like this model) support supervision and acknowledgments, improving reliability over one-way devices that simply transmit events. Many lower-cost sounders offer one-way communication only.
- Encryption:AES‑128 encryption is an important security feature. Some budget competitors may lack encryption or use weaker methods, increasing risk in sensitive installations.
- Sound level and duration:With 90–110 dB output and configurable activation times up to 900 s, the DS-PS1-I-WE(B) is comparable to higher-end internal sirens. Cheaper units may offer lower dB levels and fixed durations.
- Battery life and maintenance:Use of CR123A cells and an efficient RF protocol leads to multi-year battery life. Competitors that use smaller coin cells or higher-power transmission may require more frequent replacements.
- Integration & app support:Seamless remote configuration via AX Pro / Hik‑Connect app simplifies commissioning. Non-proprietary sounders may require manual programming or offer limited integration.
In short, the DS-PS1-I-WE(B) sits between entry-level wireless sounders and high-end hardwired sirens: offering the convenience of wireless installation with professional features (two-way RF, encryption, tamper detection) suitable for residential and Grade 2 commercial applications.
