Consider providing extra resilience for your utilities.

- Fire alarm panels and suppression systems
- BMS/Fire communications equipment
- Building access and security systems
How regularly are you testing your fire alarm panel or BMS? Do they have internal batteries to safeguard against power cuts? Does a power cut disrupt communication between your various systems despite some components having an internal battery?
If a power cut occurs because of a fire you need to maintain control of your building. In 2017 the Fire Industry Association warned that as the UK’s Public Switched Telephone Network (PSTN) is phased out in the coming years in favour of VoIP and SIP, many systems will not be able to dial out to send emergency messages. They currently rely on the low voltage supply from the traditional telephone line. Ensure all parts of your fire alarm and BMS system are protected and perform regular testing hand in hand with mains fail testing.
Even modern self-contained emergency lighting units require a regular battery change after four or five years. Whether the emergency lighting units have internal batteries or not, you can still protect this circuit with a UPS or inverter system.
