DNH supplies loudspeaker formats for buildings, industrial sites and marine environments. Match coverage and intelligibility to the location, then confirm the exact product approvals.
No. Select a listed model and check its declaration and certificate. Similar-looking variants may have different approvals.
What Does The MED Variant Mean?
The SAFE-10P-54T-MED is offered for marine applications. Check the marine approval documents for the exact model and installation.
How Do I Choose Between A Ceiling Speaker And A Horn?
Consider room geometry, background noise, coverage and mounting position. A horn can provide directional coverage; a ceiling speaker suits a different layout.
Is Loudness The Only Important Factor?
No. Emergency messages need to be understandable. Coverage, background noise and reverberation all affect intelligibility.
Can I Connect A Speaker To Any Voice Alarm Amplifier?
Check the line system, transformer taps, load, supervision and the amplifier manufacturer’s requirements before connecting equipment.
What Should I Send For A Speaker Layout Review?
Provide plans, mounting heights, ambient-noise information, the voice alarm system and any fire or marine approval requirements.
Can You Help Identify A Replacement?
Send the full part number and clear photographs of the equipment label. Include the system it connects to so the replacement can be checked.
What Should I Include In My Enquiry?
Include the model or project drawings, quantity, delivery country, required date and any specified approvals.
