Bosch

Internal screamers produce a strong audible warning inside a home or business when the alarm output is activated. Their high-pitched sound can alert occupants and make the protected area uncomfortable for an intruder.

• WP05 flush-mounted piezo screamer – Designed for a neat, recessed indoor finish where the installation allows.
• WP08 top-hat piezo screamer – A compact surface-style option for internal audible warning.

Confirm the operating voltage, current draw, mounting depth, sound output and panel connection before replacing or adding an internal screamer.

An external alarm warning assembly may combine a weather-resistant cover, horn speaker, flashing strobe or LED and tamper protection. The exact components vary between products.

• HC-WPSC – Bosch plastic external siren cover with horn speaker and LED light, as stated in the product listing.
• WP16 – Hills Reliance external slimline siren combination with strobe.
• Secor slimline siren – Review the listing carefully to confirm which siren-box components are supplied.

Outdoor equipment must be positioned and sealed correctly. Confirm the environmental rating, tamper arrangement and cable entry before installation.

The collection includes Bosch alarm accessory kits such as K0007, K0011 and BOSCH7015/BOSCH7016 variants. Kit names can appear similar, but their internal screamer style, siren-box components and supplied accessories may differ.

• Check whether the selected option is flush-mounted or top-hat.
• Confirm whether an external cover, horn, strobe or LED is included.
• Check whether internal and external sounders are both supplied.
• Do not assume cable, backup battery, transformer or installation hardware is included unless listed.

Use the individual product’s inclusions list and selected variant as the final reference before ordering.

Many conventional wired alarm sounders can be used with a compatible Bosch alarm output, but suitability must be checked against the complete system design.

• Confirm the panel model and programmed output function.
• Check the required operating voltage and polarity.
• Add the current draw of every connected horn, screamer, strobe and relay.
• Confirm the panel output and auxiliary power limits are not exceeded.
• Use a suitable relay or separate power supply where required by the design.

Products should not be treated as universally compatible with every Solution 2000, Solution 3000 or Solution 6000 configuration.

This category is organised for Bosch alarm applications, but not every listed product is manufactured by Bosch.

• Bosch-branded products carry Bosch product naming or model information.
• Hills and Secor accessories may be used as compatible warning components when their electrical and installation requirements suit the Bosch system.
• Night Sabre PoE security lighting has separate power and integration requirements and should not be selected as a direct replacement for a conventional siren output.

Confirm the brand, model, intended function and compatibility shown on each product page before purchase.

• Install internal screamers where occupants can hear them without creating an avoidable hazard.
• Position external siren boxes for visibility, weather protection and service access.
• Protect wiring and use the required tamper circuit where supported.
• Program the correct alarm output behaviour and activation duration.
• Test the audible output, strobe, tamper and standby-battery operation after installation.

Professional installation is recommended. Loud sounders can present a hearing risk at close range, and incorrect wiring or excessive output load can damage equipment or reduce system reliability.

Complete the system with the correct compatible equipment:

• Bosch alarm accessories – Modules, receivers, power supplies, enclosures, PCB boards and other installation parts.
• Bosch motion detectors – Wired, wireless, PIR, Quad PIR, TriTech and specialist detection.
• Bosch code pads – User controls for compatible Bosch alarm panels.
• Bosch remote controls – Keyfobs and transmitters requiring the appropriate receiver and programming.
