1.0 Introduction to the PWE-6FT Enclosure, continued
1.2 Optional Features, continued
STH (Storm Hood Kit)
Enclosures equipped with the optional Storm Hood Kit offer additional protection from possible
dirt and snow ingress. If the enclosure is equipped with Storm Hoods, Alpha recommends the
use of the ECF (Enclosure Cooling Fan).
TMPR SW (Tamper Switch)
The Tamper Switch provides a magnetic door switch which plugs into the USM option for XM
power supplies and the USM2 for XM Series 2 power supplies. Most status monitoring systems
provide an alarm if the enclosure door is opened. Tamper Switches are available either as
normally open (NO) or normally closed (NC).
