Pyronix Deltabell‑X Module FPDELTAX2MOD, Grade 2 External Sounder Module, Twin Piezo, 104 dB

Introduction to the Pyronix Deltabell‑X Module (FPDELTAX2MOD)

The Pyronix Deltabell‑X Module (FPDELTAX2MOD) is an electronics module designed to form the core of a Grade 2 external siren assembly. As part of the Deltabell‑X family, this module provides twin‑piezo sound output, an integrated visual strobe/backlight capability and installer‑friendly features such as a hinged lid, self‑levelling mounting and an engineer hold‑off to prevent accidental activation during service. With a quoted sound level of 104 dB(A) and an IP65 weatherproof rating, the Deltabell‑X module is targeted at residential and light commercial intruder alarm installations where reliable audible and visual deterrence is required.

Key features at a glance

• Model:FPDELTAX2MOD — Deltabell‑X electronics module (module only; requires Deltabell cover/backplate or Lightbox).
• Sound output:Twin piezo sounder rated at 104 dB(A).
• Visual alarm:Integrated flashing strobe and optional Lightbox for backlight/night visibility.
• Installer conveniences:Hinged lid, self‑levelling mechanism and engineer hold‑off.
• Security grade & environment:Grade 2 wired external sounder module, IP65 weatherproof.

Detailed specifications and benefits

• Sound Level:104 dB(A) — a high audible output designed to deter intruders and alert neighbours. The twin piezo arrangement delivers consistent, attention‑grabbing tones.
• Number of piezos:2 (twin piezo) — redundancy and stronger combined acoustic output compared with single‑piez o configurations.
• Strobe rate:10 ms pulse at 1 Hz — provides a clear visual alarm pattern for rapid recognition.
• Auto cut‑off:15 minutes — conserves system resources and complies with many local nuisance‑reduction practices while still providing a meaningful alarm period.

• Tamper:Multi‑way tamper protection (lid & base/rear) helps prevent removal or tampering with the module without triggering a tamper alarm.
• Mounting:Self‑levelling mechanism and hinged lid simplify installation and maintenance; hinged lid makes cabling and servicing quicker for engineers.
• Ingress protection:IP65 rated — suitable for exposed external use with protection against dust and low‑pressure water jets, extending the range of installation locations.
• Operating voltage:Typical Deltabell family range is 9–16 V — confirm exact values in the official datasheet prior to installation.

• Engineer hold‑off:Prevents accidental activation during installation or service, reducing the risk of nuisance triggers and allowing safe work on the system.
• Module design:This SKU is the electronics module only; it requires a Deltabell cover/backplate or Lightbox to create a complete external siren assembly. This modularity lets installers stock fewer full‑kit units and mix configurations as needed.

Use cases and scenarios where the Deltabell‑X excels

• Residential properties:For homes seeking a visible and audible deterrent, the 104 dB output and flashing strobe provide a robust alarm presence without the complexity of larger commercial sirens.
• Light commercial premises:Small offices, retail units and outbuildings benefit from Grade 2 compliance and the IP65 weatherproofing, making the module appropriate for shopfronts and small business exteriors.
• Retrofit and modular installations:Since the FPDELTAX2MOD is a module rather than a complete enclosure, it is ideal for installers upgrading existing Deltabell covers or offering tailored Lightbox/backplate combinations for different customer aesthetics or visibility needs.
• Locations requiring visual notification:Where audible alarms might not be sufficient or during noisy periods, the strobe and optional Lightbox provide clear visual signalling for neighbours and passers‑by.
• Environments with weather exposure:IP65 ingress protection means the unit performs reliably on exposed walls, eaves and other outdoor mounting points subject to rain and dust.

Comparisons with similar products on the market

In the Grade 2 external sounder category, installers and specifiers typically weigh sound output, tamper features, weatherproofing and installer conveniences. The Deltabell‑X module compares favorably across these dimensions:

• Sound output:With 104 dB(A), the FPDELTAX2MOD sits in the higher range of twin‑piezo modules. Some competing Grade 2 modules advertise similar dB levels, but combined factors such as piezo quality, enclosure acoustics and installation height affect real‑world audibility.
• Modularity:Many competitor sirens are sold as complete units only. The Deltabell‑X module’s electronics‑only SKU offers flexibility for installers to pair with different covers or Lightboxes — a logistical and inventory advantage.
• Installer features:Hinged lids and engineer hold‑offs are increasingly expected, but not universal. The Deltabell‑X’s self‑levelling mechanism and multi‑way tamper compare well to market alternatives where installers might otherwise need to add third‑party tamper solutions.
• Weatherproofing:IP65 is a common rating for external sounders. Some higher‑spec models offer IP66 or IP67 ratings for extreme conditions; for most domestic and light commercial installations IP65 provides a reliable balance of protection and cost.
• Price and value:The modular nature and installer‑centric features position the FPDELTAX2MOD as a competitive choice for installers aiming to balance performance and cost. Pricing examples (see below) show how the module can fit different commercial strategies — from competitive retail pricing to premium full‑kit offerings.

Pricing guidance and commercial considerations

• Cost basis:Based on reseller evidence, the cost price provided (29.74) is most likely in GBP. This article assumes that value is GBP and applies margin calculations accordingly.
• Margin examples:To guarantee a 16% margin you would price the product at approximately 35.41. A suggested retail price of 39.99 gives an approximate 25.6% margin. If selling as a premium full kit (module plus Lightbox/cover), retail pricing could sit in the 49.99 54.99 range depending on configuration.
• Stocking strategy:Installing businesses may prefer to stock the module and select covers on demand to minimise inventory while catering to bespoke customer aesthetics or enhanced visibility options.

Customer feedback and installer impressions

While individual testimonials are not supplied with this product brief, installer and reseller listings for the Deltabell‑X family commonly highlight several recurring points of feedback:

• Installers appreciate the hinged lid and engineer hold‑off as time‑saving and safety features during commissioning and maintenance.
• Users and installers note the 104 dB(A) output is an effective deterrent in typical residential and small commercial scenarios.
• The modular design is frequently mentioned as a logistical benefit, enabling tailored kits and reduced waste when replacing electronics only.
• Feedback on weatherproofing and build quality is generally positive for the expected use cases; for extreme environments some installers opt for higher IP‑rated alternatives.

Installation, compliance and final considerations

• Confirm wiring, operating voltages and current consumption from the official Pyronix Deltabell‑X datasheet and installation manual prior to installation.
• Only competent, qualified engineers should install or service external sounders — isolate supplies and adhere to local codes and regulations.
• Remember this SKU is the electronics module only. Ensure you pair it with a compatible Deltabell cover/backplate or Lightbox to complete the external siren assembly.

Conclusion: Why choose the FPDELTAX2MOD?

The Pyronix Deltabell‑X Module FPDELTAX2MOD is a practical, installer‑friendly choice for those specifying Grade 2 external sounders. It combines a strong 104 dB(A) twin‑piezo output with useful visual signalling, robust tamper protection and weatherproofing suitable for most residential and light commercial sites. Its modular approach gives installers flexibility and stock control, while features such as a hinged lid and engineer hold‑off make commissioning and servicing safer and faster. When paired with the appropriate Deltabell cover or Lightbox, the FPDELTAX2MOD offers a balanced mix of performance, value and convenience for many external alarm installations.
