Introduction to the Twin Alert Internal Sounder (FP10800) and its key features
The Twin Alert Internal Sounder (model FP10800) is a compact combined internal sounder and speaker designed for wired intruder alarm systems. Built to deliver clear keypad tones and a powerful local siren, the unit pairs a dedicated speaker for system status with a 100 dB(A) internal siren that overrides the speaker when an alarm is triggered. With tamper protection, an engineer hold-off facility for servicing, and a compact footprint that supports wall or ceiling mounting, the Twin Alert is aimed at domestic and small commercial installations where reliable audible signalling and ease of installation matter.
Detailed description of specifications and benefits
The Twin Alert FP10800 balances small size with practical features that installers and end users will appreciate. Key specifications include:
- Model:FP10800 (Twin Alert internal sounder)
- Loudness:100 dB @ 1 m — loud enough to provide a clear local alarm for most domestic and small commercial premises.
- Electrical:Operating voltage 9–14.5 V (13.5 V nominal). Alarm current approximately 160 mA and quiescent current approximately 30 mA @ 12 V, which keeps standby power draw modest on typical alarm system power supplies.
- Physical:Compact dimensions of 90 × 90 × 46 mm and a lightweight design (≈100 g) make the unit simple to fit on walls or ceilings with minimal intrusion into interior spaces.
- Security & safety:Tamper protection is included, along with an engineer hold-off facility to disable tamper trips during servicing. The product is certified to standards including EN50131 and PD6662 and is rated Security Grade 2, with CE and UKCA declarations available.
- Durability:Environmental ratings give storage temperature range from −20 °C to +60 °C and operating range from −10 °C to +40 °C, suitable for internal environments across most climates.
- Warranty:2-year manufacturer warranty for added peace of mind.
Benefits of these specifications translate into practical advantages on site. The 100 dB siren provides an authoritative local alert to deter intruders and alert occupants or neighbours. Having a combined speaker and siren reduces the need for separate devices, saving space and simplifying wiring. The modest quiescent current helps preserve battery-backed power systems, and the engineer hold-off makes routine maintenance less disruptive. Finally, the Grade 2 certification confirms the product meets recognised security standards for many residential and small-business applications.
Use cases and scenarios where the Twin Alert excels
The Twin Alert internal sounder is particularly well suited to several common installation scenarios:
- Domestic homes:For houses and apartments where a discreet but powerful internal alarm is required, the small size and combined speaker/siren design allow placement in hallways, living rooms, or utility areas without major visual impact.
- Small commercial premises:Retail shops, small offices, salons and cafes can benefit from a Grade 2 certified internal sounder that provides local signalling and tamper protection without the scale or expense of larger commercial sirens.
- Supplementary internal signalling:In larger systems, the Twin Alert can be used as an additional internal unit to ensure audible coverage in specific rooms, such as server rooms, storage areas, or managers' offices.
- Installer-friendly service points:The engineer hold-off option simplifies servicing. When engineers need to perform tests or maintenance without tripping tamper alerts or generating unnecessary alarms, the hold-off reduces callbacks and nuisance alarms.
- DIY or basic professional installs:With straightforward wiring and low weight, the Twin Alert is suitable for experienced DIYers and professional installers who need a reliable, compact internal alarm device.
Because it is rated for internal use and has a moderate environmental range, the Twin Alert should be installed indoors where it is protected from water and extreme temperatures. It is optimized for scenarios where local audible signalling is required rather than loud external warning for wide-area deterrence.
Comparisons with similar products on the market
When choosing an internal alarm sounder, key factors to weigh include loudness, feature set (such as combined speaker and siren, tamper contacts, and service modes), certification, size, and power consumption. The Twin Alert offers a competitive blend of these characteristics.
- Combined speaker + siren vs separate devices:Many installers use separate keypad speakers and sirens. The Twin Alert consolidates both functions into one compact housing, simplifying wiring and saving wall space compared with a separate siren and speaker pair.
- 100 dB output vs higher-power sirens:Some external or larger internal sirens offer higher dB ratings (110–120 dB) suitable for external deterrence. For most internal applications the Twin Alert's 100 dB is ample—providing a loud, attention-grabbing tone without the overbearing volume of large external sirens designed for outdoor use.
- Security grade and standards:The Grade 2 rating and EN50131 compliance position the Twin Alert alongside other quality internal sounders intended for residential and small commercial installations. Higher-grade devices (Grade 3 or 4) are aimed at higher-risk premises and typically come with additional features and certification costs that may be unnecessary for typical houses and small businesses.
- Power consumption:With alarm current ≈160 mA and quiescent ≈30 mA, the Twin Alert is economical enough for battery-backed systems. Some alternative sounders have higher standby draws, which can impact battery sizing for alarm panels.
Overall, its compact footprint, combined functionality, and certification make the Twin Alert a practical choice in its class. Installers choosing between options should consider whether they need higher outdoor output, additional features such as built-in strobes, or a higher security grade before selecting a different model.
