Klaxon SLM-0001 Master Blaster 127dB 230V Industrial Alarm Siren Yellow

Up to 127 dB at 1m. Decibels (dB) measure sound pressure level, and at this figure the Klaxon SLM-0001 Master Blaster 127dB 230V Industrial Alarm Siren Yellow is a high-output sounder for areas where a strong audible warning is needed to deter intrusion or alert personnel.

What each spec means on the job

• 230V AC, motor-driven: it runs from a 230V alternating current (AC) mains supply.
• 12V DC trigger relay: your alarm control panel sends a 12V direct current (DC) signal to switch the siren on. The relay is internal to the unit.
• Continuous rating: it is rated to keep sounding in demanding industrial installations.
• -30°C to +45°C: the operating range covers internal or external positions.
• Surface bracket and 1m cable: the mounting bracket is supplied, and the siren arrives pre-wired with a 1m cable for connection.
• Yellow housing.

What else you need

1. A 230V AC mains supply to the siren.
2. An intruder alarm control panel or security signalling system that can provide the 12V DC trigger.

This is a supplementary sounder, not a complete alarm. It is commonly used in warehouses, factories, plant rooms and other industrial sites that need a high-volume audible signal.
