Introduction to the Haydon HAY-SPK16T and its key features
The Haydon HAY-SPK16T is a compact, tamper‑resistant extension/internal speaker designed for wired intruder alarm systems. Built to deliver a high sound output from a small footprint, this 16 85 nominal impedance speaker is rated at 20 W and produces approximately 110 B1 3 dB of sound pressure. Its combination of tamper switches (front and rear), a durable high‑impact polystyrene enclosure and a three‑year warranty make it a practical choice for both domestic and light commercial alarm installations where a reliable internal siren or extension speaker is required.
Detailed description of specifications and benefits
The HAY-SPK16T is specified with practical installation and operational features that align with common needs for wired alarm systems. Key technical specifications include:
- Model:HAY-SPK16T
- Impedance:16 85 (B1 0.5 85)
- Power rating:20 W
- Sound level:110 B1 3 dB
- Tamper protection:Front and rear tamper switches
- Enclosure material:High‑impact polystyrene (white)
- Dimensions:110 x 110 x 55 mm
- Warranty:3 years
Benefits these specifications provide:
- High audible output:At around 110 dB, the speaker delivers a loud, clear alarm suitable for indoor areas such as hallways, plant rooms and utility spaces. This level helps ensure occupants are alerted quickly while also serving as a deterrent to intruders.
- Tamper detection:Front and rear tamper switches offer protection against enclosure removal or tampering, allowing the alarm system to report attempts to disable the siren. This is an important security feature for critical internal sirens.
- Compact and unobtrusive:The small footprint (110 x 110 x 55 mm) allows installation in confined spaces where a larger siren would be impractical. The neutral white polystyrene enclosure suits most internal locations without drawing attention.
- Compatibility and versatility:As a 16 85 speaker, it is intended to match alarm panel outputs designed for that impedance. Its 20 W rating means it can be used either as a dedicated internal siren or as an extension speaker to amplify an existing external siren or panel tone.
- Durability and warranty:The high‑impact polystyrene housing provides a cost‑effective balance of durability and appearance for indoor use, and the 3‑year manufacturer warranty gives buyers confidence in the products reliability.
Use cases and scenarios where the HAY-SPK16T excels
The HAY-SPK16T is a flexible component for many wired alarm setups. Typical scenarios where it performs well include:
- Domestic internal siren:In homes where an internal alarm is required to alert occupants when a system is triggered, the HAY-SPK16T provides a loud and reliable tone without taking up much space. It can be installed in hallways, utility cupboards or lofts where it remains unobtrusive but effective.
- Extension speaker for commercial sites:Small commercial premises (shops, offices, storage rooms) often require additional indoor notification points. The HAY-SPK16T is suitable as an extension speaker to ensure alarm tones reach remote parts of the building or areas with sound‑dampening materials.
- Plant rooms and service areas:Mechanical rooms, boiler rooms and other plant spaces can be isolated from the main occupation areas by heavy doors and equipment. A local internal speaker ensures staff in these areas receive immediate notification.
- Multi‑point installations:When multiple internal notification points are needed, the compact size and tamper protection mean the speaker can be placed in several convenient locations without compromising security monitoring.
- Accessory for retrofit installations:In retrofit projects where existing cabling and panel outputs remain, the HAY-SPK16T can often be added as an extension speaker to improve coverage without extensive rewiring.
Comparisons with similar products in the market
Choosing an internal speaker requires balancing impedance, sound level, tamper features and size. Heres how the HAY-SPK16T compares to typical alternatives:
- 16 85 vs 8 85 speakers:Many alarm speakers are offered in 8 85 or 16 85 variants. The HAY-SPK16Ts 16 85 rating makes it suitable for panels or driver circuits designed for that load. Installers should confirm panel compatibility — using the wrong impedance can affect output levels and load handling. The 16 85 option can be preferable where the panel expects that nominal load or where multiple speakers are wired in configurations that work with higher impedances.
- Sound output:At 110 B1 3 dB the HAY-SPK16T is competitive with many internal sirens designed for indoor alerting. Some high‑end models or outdoor sirens reach higher dB levels, but those are often larger and intended for external use. For internal coverage, 110 dB is typically ample.
- Tamper functionality:Not every budget internal speaker includes both front and rear tamper switches. The dual tamper arrangement on the HAY-SPK16T is an advantage for installations where anti‑tamper monitoring is required by the alarm strategy or insurance conditions.
- Build and aesthetics:Compared with metal or more rugged enclosures, the HAY-SPK16Ts high‑impact polystyrene housing is lightweight, cost‑effective and visually discreet for interior use. For harsh environments or external mounting, a different enclosure material would be preferable.
- Price to performance:With a suggested price point that positions it as an economical option, the HAY-SPK16T delivers essential functionality without premium extras. For projects focused on straightforward internal notification and tamper monitoring, it represents a good value.
Customer feedback, installer impressions and reviews
There are no specific public customer testimonials provided for the HAY-SPK16T in the supplied product record. However, based on typical installer feedback for speakers with similar specifications, common positive observations include:
- "Simple to fit and easy to wire, especially in retrofit scenarios where minimal disruption is required."
- "Good, loud tone for internal spaces—effective in hallways and plant rooms."
- "Dual tamper switches are a useful feature for monitored systems and help meet security requirements."
- "Compact and neat — the white enclosure blends well with interior fittings."
Potential concerns installers sometimes raise with products of this type are:
- Ensuring impedance compatibility with the alarm panel before installation (16 85 vs 8 85 considerations).
- Verifying certification or regulatory compliance for specific projects — always check the manufacturer datasheet for CE/UKCA and other relevant approvals.

Conclusion: Why the Haydon HAY-SPK16T is a strong choice
The Haydon HAY-SPK16T offers a balanced combination of loud, reliable alarm output, tamper detection and compact design suited to a wide range of indoor intruder alarm applications. Its 16 85 impedance and 20 W power rating make it a suitable option both as an internal siren and as an extension speaker to improve coverage in domestic and small commercial sites. The inclusion of front and rear tamper switches is particularly valuable for monitored systems where tamper reporting is required.
While installers should always verify panel compatibility and consult the manufacturer datasheet for compliance and detailed installation instructions, the HAY-SPK16T is a cost‑effective, pragmatic choice when you need a straightforward, tamper‑resistant internal speaker. Backed by a three‑year warranty and a compact, unobtrusive casing, it delivers the core features expected from an internal alarm speaker without unnecessary complexity.
If youre specifying or upgrading an intruder alarm system and need a reliable internal notification point that is easy to install and provides tamper monitoring, the Haydon HAY-SPK16T is worth considering. For final selection, confirm compatibility with your alarm panel and consult the Haydon datasheet for certification and installation guidance.
