Siren - Announcement Systems are known for having a wide sound range and a variety of different siren tones. These systems are designed to be used in various emergency or special situations. High volume and clearly understandable announcement feature make these systems effective and remarkable.
Siren - Announcement Systems are ideal for police, fire, emergency medical services and other security services. ARMAS manufactures these systems with high quality materials and superior craftsmanship, thus ensuring that users are safe and under control in all situations.
Specifying a Siren and PA System for Your Fleet
A siren amplifier produces the warning tones a vehicle projects, while its public address (PA) function lets the crew give spoken instructions through a microphone — two distinct jobs handled by a single unit. When drafting a specification, begin with the vehicle's electrical architecture: passenger cars typically run on 12V, while trucks and buses mostly use 24V, and the amplifier must match. Then define how the operator will control the system while driving, whether PA capability is required, and how much console space is available. The e-SRN family and the EXPERT series address different installation and control preferences; exact figures for each model are published in the specification table on its product page. An amplifier performs only as well as the speaker it drives, and most fleet projects pair it with visual warning equipment for a complete package. ARMAS has manufactured warning electronics in Ankara since 2005, exporting worldwide with ISO 9001 and ISO 13485 certified processes and an in-house R&D center.
| Project Requirement | Why It Matters | What to Check |
|---|---|---|
| Supply voltage | The amplifier must match the vehicle's 12V or 24V system | Confirm the electrical system of every vehicle type in the fleet before ordering |
| PA capability | Spoken instructions for traffic and crowd management | Specify a microphone-equipped model where verbal guidance is part of the mission |
| Operator ergonomics | Controls must be reachable without leaving the road unattended | Compare panel, handheld and button-based control layouts on the product pages |
| Fleet standardization | Mixed vehicle types complicate training and spares | Select model families that cover the whole fleet with a common control logic |
Frequently Asked Questions
What is the difference between the siren and the PA function?
The siren draws attention with predefined warning tones, while the PA function transmits the operator's voice through the same speaker. In emergency vehicles both are usually combined in one amplifier.
Can sirens be fitted to any vehicle?
The use of audible and visual warning equipment is governed by traffic regulations, which differ from country to country. Please verify the rules that apply to your vehicle with the relevant local authority.
How do I confirm compatibility between amplifier and speaker?
Power and impedance values must match. Compare the specification tables on both product pages, or ask our team to validate your configuration before purchase.
Do you supply OEM and government fleet projects?
ARMAS works with vehicle manufacturers including BMC, Otokar, Toyota and Ford, and its references include Turkish public institutions such as the Police, Gendarmerie and Ministry of Health. Reach us via the contact page for project support.
