An emergency illumination lamp (DC lamp) can be mounted
for buildings with frequent power failure. Battery room must
be equipped with anti-explosion lamps and the light needs not
to be too intense.
In addition, direct sunshine must be avoided. To this aim, pa-
per or paint can be used on external window.
� Atmospheric pressure
Working: 108000Pa~51000Pa
Storage: 108000Pa~12000Pa
� Air Pollution
The product must not be exposed in corrosive gases such as
sulfured hydrogen, sulfur dioxide and ammonia oxide, and
