Pyronix DELTA/MOD‑WE2 Deltabell‑WE Wireless External Bellbox, 100 dB, 868 MHz, 4×CR123A

Introduction: Pyronix Deltabell WE2 Wireless External Bellbox and its key features

Pyronix DELTA/MOD‑WE2 (Deltabell‑WE)is a purpose‑built wireless external bellbox designed to work with Pyronix Enforcer intruder alarm systems. It combines a high‑output sounder, a bright visual strobe and multiple tamper protections in a weather‑resistant polycarbonate enclosure. With two‑way 868 MHz Enforcer radio communications (including SSI, anti‑jamming and encrypted rolling codes), selectable comfort LED, removable covers for neat installation and support for both battery and external 12 V DC power, the Deltabell WE2 is intended to be an installer‑friendly deterrent for domestic and light commercial sites.

Key highlights at a glance:

• High output alarm:Manufacturer specifies 100 dB(A) at 1 metre.
• Two‑way wireless:868 MHz Enforcer protocol with signal strength indication and anti‑jamming measures.
• Robust construction:Weather‑resistant polycarbonate housing with rotatable fixing dogs and levelling aid.
• Comprehensive tamper protection:Lid, base and power tamper monitoring.
• Flexible power options:4 × CR123A user‑replaceable batteries (manufacturer recommends BATT‑VARTA‑CR123A) or external 12 V DC input.

The Deltabell WE2 is engineered with the practical needs of installers and end users in mind. Below are the most relevant technical details and the benefits they deliver in real installations.

• Sound output:Rated at 100 dB(A) @ 1 m (manufacturer). This level provides a strong audible deterrent for intruders and gives neighbours or passersby a clear alarm cue. Note that some reseller documentation may list a lower figure (e.g. 94 dB(A)); always confirm the sound rating on the supplied datasheet.
• Sounder cut‑off:Configurable cut‑off up to 15 minutes maximum, helping to balance deterrence with nuisance reduction and local regulations.
• Strobe & LED indicators:A flashing LED strobe (10 ms pulse at 1 Hz) provides a visual alarm signal, and a selectable comfort LED may be enabled or disabled based on site preference.
• Wireless communications:Enforcer 868 MHz FM transceiver with encrypted rolling code, SSI (signal strength indication) and anti‑jamming features. Two‑way communication helps confirm status and improves reliability compared with simple one‑way devices.
• Range:Up to approximately 300 m open‑air range — sufficient for typical domestic and many commercial layouts. Walls, metalwork or other RF obstacles will reduce this range; careful site surveying during installation is recommended.
• Power:Uses 4 × CR123A batteries (user‑replaceable) with an expected life of up to around two years depending on usage patterns. The option for an external 12 V DC input gives installers a hard‑wired power fallback where desired.
• Tamper protection:Lid, base and power tamper monitoring add protection against casual or determined attempts to disable or remove the unit.
• Build & installation features:Weather‑resistant polycarbonate construction, rotatable fixing dogs for easier mounting, integral levelling aid and removable covers for neat cable routing and tidy installation finish.
• Certifications:Listed as Security Grade 2 with IMQ/EN certifications per the manufacturer's datasheet; install in accordance with the Pyronix guide to maintain warranty and compliance.

The Deltabell WE2 is particularly well suited to situations where a visible and audible external deterrent is required but running signal or power cabling would be costly or impractical. Typical use cases include:

• Domestic properties:Detached and semi‑detached homes benefit from an external siren that alerts neighbours and deters opportunistic intruders. The strobe and 100 dB sound output make the presence of an alarm obvious.
• Retrofit installations:When upgrading older systems to a Pyronix Enforcer panel, the wireless Deltabell lets installers add a high‑performance external bellbox without chasing external wiring or disturbing finishes.
• Light commercial sites:Small shops, offices and workshops where cabling costs or landlord constraints make wired sounders difficult. Tamper monitoring suits premises where vandalism is a risk.
• Remote or temporary sites:Buildings or locations with intermittent occupancy (holiday homes, temporary sites) where battery operation and wireless communications simplify deployment.
• Properties with challenging access:Where routing conduit or cabling externally is restricted by architectural features or conservation requirements, the wireless and battery options reduce the need for invasive work.

When assessing the Deltabell WE2, it helps to compare it to two broad alternatives: wired external bellboxes and other wireless external sirens.

• Wired external bellboxes:Wired units typically offer a permanently powered connection which can provide continuous readiness and avoid battery replacement. They may offer higher continuous output options and simplified supervision via hardwired fault circuits. However, installation cost and visual impact of conduit and trunking can be significant — especially on retrofit projects. The Deltabell WE2 shines where cabling is a barrier, offering almost the same functionality with wireless supervision and tamper protection.
• Other wireless external sirens:Competing wireless sirens from other manufacturers vary by sound output, radio protocol and tamper features. Some affordable units advertise sound levels around 94 dB(A), which is still audible but noticeably lower than the Deltabell’s 100 dB(A) manufacturer rating. Differences to consider:Radio reliability: Pyronix Enforcer two‑way communication with SSI and anti‑jamming gives installers diagnostic confidence. Other systems may use one‑way transmitters or less robust telemetry.Battery life and power options: The use of CR123A cells is common; the Deltabell also accepts external 12 V DC, which some competing battery‑only units lack.Certification and security grade: The Deltabell’s Grade 2 listing is relevant for insurance and specification; verify competitor certification if this matters for the installation.

Publicly available reviews for specific model numbers can vary by reseller and site — where professional installer feedback is available it tends to highlight the following recurring themes. The quotes below are illustrative of common, anonymised comments from installers and end users rather than verbatim sourced testimonials.

• "Quick to mount and commission with Enforcer panels — the SSI and signal reporting make it easy to position for reliable links." — Installer feedback
• "Effective deterrent: neighbours commented on how loud and visible the alarm was during testing." — Homeowner observation
• "Battery life has been good over the first year, and the option to use external 12 V is handy for sites where mains power was later added." — Small business owner

If you're specifying the unit for a client, ask for site‑specific references or seek demonstration units from distributors to validate fit and performance on your particular properties.

To get the best results from a Deltabell WE2 installation:

• Survey radio coverage during initial site visits — place the bellbox where the panel reports a strong SSI level to avoid intermittent alarm issues.
• Respect the recommended battery type and monitor battery status via the Enforcer system; using the recommended CR123A brand can help achieve expected life.
• Consider sightlines for the strobe — placing the unit where it’s visible from the street maximises visual deterrence.
• Observe local noise ordinances and configure sounder cut‑off appropriately to balance deterrence with nuisance management.
• Follow Pyronix installation guidance to maintain certification and ensure tamper circuits are correctly connected and tested.

The Pyronix DELTA/MOD‑WE2 Deltabell‑WE offers an attractive mix of features for installers and end users seeking a wireless external deterrent for Pyronix Enforcer systems. Its high‑output sounder, bright strobe, robust tamper protections and two‑way Enforcer radio make it a reliable option for homes and small commercial sites where running external cabling is undesirable or impractical. The flexibility of battery operation combined with external 12 V input, installer‑friendly mounting features and Grade 2 certification contribute to a competitive package.

For projects that prioritise ease of installation, visible deterrence and strong wireless supervision, the Deltabell WE2 is a practical choice. As with any security equipment, verify the supplied datasheet for the definitive technical figures (noting the occasional discrepancy in reseller specs), carry out a radio survey on site and follow the manufacturer’s installation guidance to ensure optimal performance and compliance.
