Frequently Asked Questions - SG1250 ABUS

How to install the SG1250 siren?

Fix the siren to the wall using the provided mounting points. Connect the 12V DC power supply to the +12V terminal. Connect the -Hi or -Lo terminal to ground (0V) to activate the siren. Make sure to integrate the Tamper contact into your system's tamper monitoring.

What type of signal should be used to trigger the siren?

The siren is triggered by a negative signal (0V) applied to the -Hi terminal (maximum volume, 110 dB) or -Lo terminal (reduced volume, 90 dB). The signal must be maintained for the entire duration of the alarm.

What is the difference between the -Hi and -Lo terminals?

The -Hi terminal activates the siren at 110 dB, while the -Lo terminal activates it at 90 dB. Use -Hi for a powerful alarm and -Lo for a less intense alert.

How to activate the built-in LED?

The LED is activated by applying a negative signal (0V) to the -LED terminal. This can be used, for example, to simulate presence or indicate system activation.

What to do if the siren does not work?

First check the 12V DC power supply and connections to the terminals. Ensure the trigger signal is 0V. Also check the Tamper contact (anti-tamper) which must be closed. If the problem persists, contact ABUS after-sales service.

Can I use the siren outdoors?

No, the SG1250 siren is designed only for indoor use. Its IP54 protection rating does not guarantee protection against prolonged exposure to rain or humidity. Outdoor use could damage it.

What are the dimensions of the siren?

The dimensions are 155 mm height, 100 mm width, and 48 mm depth. It is compact and can be easily installed in a discreet corner.

Is the siren compatible with all alarm systems?

Yes, the SG1250 siren is compatible with any alarm system providing a negative trigger signal (0V) and 12V DC power supply. It can be used as an additional indoor siren.

How to test the tamper contact?

The Tamper contact is a normally closed (NC) switch. To test it, measure continuity between the two terminals: it should be zero. When the siren cover is opened, the contact opens, which can trigger an alarm if your system monitors it.

Where can I find the declaration of conformity?

The declaration of conformity is available from the manufacturer ABUS. It certifies that the product complies with European Directive 1995/5/EC (R&TTE). You can request it via customer service.
