ENCLOSURE FOR A SUMP PUMP ALARM |
摘要 |
A sump pump has a float operated alarm switch mounted on the top end of the pump housing for activating an alarm when water rises above a normal operating level. The alarm is in a remote enclosure with the pump power plug so that plugging in the unit automatically positions the alarm in a desirable location to be heard. The power cord and alarm switch wire extend through a flexible corrugated tube that is attached to the pump housing and the alarm enclosure by strain relief connections that do not compressively crush the tube.
