Get the best fire alarm systems from McLennan

All the systems we install are ‘Open Protocol’ which gives full control and ownership to the customer. This allows the owner and users to choose who maintains their system, rather than being forced to stay with manufacturers of closed protocol systems

Wireless systems can also be installed for areas with decorative sensitivity or access restrictions.

For installations within noisy environments we can also install Visual Alert Equipment which works along-side the audible devices as standard.



If your Fire alarm is not covered by a maintenance regime it does not comply with BS 5839 Part 1

The standard recommends that your fire alarm is serviced 4 times per year, or not less than twice a year dependent on the size of the system.

The (Fire Safety) Order 2005 (FSO) applies to all non-domestic premises in England and Wales, including the common parts of blocks of flats and houses in multiple occupations.
