Regular maintenance of smoke detectors is crucial to ensure correct operation. Elekmark has the experience and knowledge necessary to test all detection and alarm systems and ensure correct placement.

Other rooms are also susceptible, with coil space heaters and fan heaters in bedrooms and living rooms also known to cause dangerous fires that can quickly get out of control.
