Public Address Systems (Hazardous Atmospheres) - Zone 1

Prior to the availability of the Spector Hazardous Area PAGA there was always a requirement for a classified "safe" area on the installation for central equipment.

However in the event of ingress of potentially explosive gas the only recourse is to disconnect uncertified equipment thereby disabling critical parts of the PAGA at the very time when vital emergency instructions or alarm tones need to be broadcast. If the central equipment is located in a safe area this would mean loss of the entire PAGA broadcast system.

Spector Lumenex has removed this serious deficiency by ensuring all parts of PAGA, including central equipment can continue to operate safely in the presence of hazardous atmospheres, thus achieving the highest safety levels possible. Two such schemes are available -

• Ex 'd' Explosionproof - recognised by Lloyds Register of Shipping
• Ex 'p' Purged or Pressurised
