Details should be clearly documented and then communicated to the relevant workforce. It should be clear that all use of emergency accounts is closely monitored. A periodic review and retraining of staff should be done to make sure the break–glass procedure continues to be relevant.

Auditing should be enabled if available, to log details of the account usage and details of the work carried out while using the account. Some systems may recognize emergency accounts and raise the system auditing level or increase audit logging of only the emergency accounts. For indoor and outdoor environments, the Universal Manual Call Point is a solid choice as it is weatherproof, its cover can be replaced easily after use, and it has a vivid and eye-catching red colour. Automatic fire door holds will listen out for the sound of a fire alarm, and automatically close the fire door after a few seconds of a fire alarm going off. They enable you to safely and legally hold fire doors open, by allowing the door to close thus preventing the spread of smoke and fire. Forgetting to document – providing written evidence of which call point you tested and when you tested it is important for the authorities and health and safety officials. Due to their use for life inherent purposes, radio receivers used in such systems should be of Category 1 [8] standard.

They are usually connected to a central fire alarm control panel which is in turn linked to the building's alarm system.
