Fischer FS1200-Siren system with control cabinet


Opt for our siren system with installation and maintenance by the professionals from Fischer Siren Construction + Alarm Systems!

In addition to the “classic” siren function, the new system is also suitable for giving voice instructions. Law enforcement agencies can use it for targeted announcements to crowds, for example to disperse gatherings or prevent mass panic.

The system can be specifically positioned at relevant points – be it at a station forecourt as in the city of Cologne or similar locations. Of course, it is also conceivable to address assembled groups in their own language in order to prevent crimes in advance.

In addition, police and other emergency forces can still be brought to the scene of an incident by means of voice announcements, even if communication via other channels is not possible.

With our system, if necessary in combination with video surveillance, you always have full control over what is happening and can intervene in a targeted manner from the control centre or operations centre at any time.

Here you can listen to the siren tone of our electronic siren as an audio file:

Open for extensions

On request, our siren systems are available in combination with 360-degree video cameras for outdoor use, which can record high-resolution video in HD quality – even without an existing network connection. Each camera is then triggered by radio from the control centre, and a USB data carrier with the recordings can be removed later for evaluation.

If a network connection via router is available, “real-time” HD video transmission via live stream is of course also possible.

Telecontrol receiver

Reliably operating remote control receivers are indispensable for the greatest possible alarm security. For the radio triggering of sirens, Fischer therefore only supplies BOS-tested devices that comply with all relevant guidelines according to TR-BOS, TR-ETS and VDE.

Our radio receivers operate in the 4 m, 2 m or 70 cm frequency range and are available for both analogue and digital radio networks.

Special filtering enables high signal sensitivity even with poor network quality. No wonder, then, that numerous government agencies such as the police, fire brigade and rescue services rely on these high-quality devices. The sophisticated design and compact construction of the telecontrol receivers we offer allow for uncomplicated installation, configuration and maintenance.

Not only siren signals and voice announcements can be triggered via telecontrol receivers: By combining them with additional relays, you can control house alarms, gates or lighting by radio.
