What are alarm signals?

Signallers (syrenes) are a key element of any alarm system. Their task is loud and/or visual warning of threat — such as burglary, fire or sabotage. After receiving a signal from the control panel, they trigger an audible alarm, flashing light or both forms at once, increasing the effectiveness of the reaction.

Types of signals

• Sound signals: They emit loud sound (syrena) → often 100–120 dB. :contentReference[oaicite:0]{index=0}
• Optical signalling devices: The flashing light (LED, stroboscope) warns visually and attractively deters intruders. {index=1}
• Optical-acoustic signalling devices: They combine sound and light → very effective in SSWiN alarms. {index=2}

Where do I put the signals?

• External: Mounted on the facade of the building. They must be resistant to atmospheric conditions, have a plastic or metal housing and anti-sabotage protection. {index=3}
• Internal: Installed, for example, in the control room or corridor to warn the residents, but also confuse the intruder. {index=4}

How do I get the right signal?

• Volume (dB): Depending on the size and character of the object → in large objects, the very loud sirens will be better. {index=5}
• Power supply: Typical signals require 12 VDCs. :contentReference[oaicite:6]{index=6}
• Degree of protection: IP-class relevant for external installation (e.g. IP54, IP65). {index=7}
• Anti-sabotage: A good signal has a housing opening detector or a separation detector from the ground. {index=8}

Most common questions (FAQ)

Can the signal function after the power cut?

Yes — many external sirens have their own emergency power supply or battery support.

Can I use an internal signal instead of an external one?

This depends on the purpose — an internal signal will warn the residents, but it may not deter the intruder as strongly as the outside with a large siren.

How many signals can I connect to the control panel?

It depends on the control panel and its output power (AUX), and the siren power consumption — it is worth consulting the installer.
