Warning Solutions That Uphold the Basics of Industrial Safety
SPK-N Series – The Most Practical Choice with the 5 Essential Signal Tones
Equipment failures often begin with small signs. However, industrial environments are typically noisy, and operators cannot continuously monitor control panels or tower lights.
For this reason, control panels require an audible alert device that can be recognized instantly.
The SPK-N is a panel-mount signal phone (electronic alarm sounder) designed to deliver equipment status through warning tones, melodies, or alarm sounds. It enables operators to quickly recognize abnormal conditions and respond faster on the production floor.
Key Features of the SPK-N
1. Clear alerts even in noisy environments
Provides a maximum sound output of 90 dB (at 1 m), ensuring reliable warning delivery in high-noise industrial settings.
2. Standard mounting hole for easy replacement and installation
Designed for the 62 × 62 mm standard panel cut-out, minimizing the need for panel layout modifications when replacing or adding units.
3. Rear volume adjustment without disassembly
The sound level can be conveniently adjusted from the rear side of the unit to suit on-site conditions.
4. Terminal block wiring for simplified installation
Equipped with a rear terminal block connection, allowing easier wiring management and maintenance.
5. Optimized sound selection (5 essential tones)
Instead of unnecessary multi-channel configurations, the SPK-N focuses on five commonly used alarm sounds in industrial environments, ensuring simple and practical operation.
· Fire alarm tone (Fire.A-ANG)
· Beeping alarm tone (Machinery Fault)
· Phone ring tone
· For Elise melody
· Stepping-stone melody
