Police Response List

Changes to Police policy have been made to reduce response levels to false alarm activations. The ACPO (Association of Chief Police Officers) Security Systems Policy 2000 now leaves monitored business premises under attack. Avoid removal from the police response list through false activations by having your company's alarm response and keyholding responsibility assessed now, before it’s too late.
