Model 630 / 631

Page Boss Paging Telephones

Our Multiguard is a simple and low cost monitoring device which is used  to provide an audible alarm on a paging circuit when a pump, fan,  power center,  etc.,  fails to operate properly.  This unit comes in  two  models  - Model 630 with a handset and Model 631 without a handset.

The MULTIGUARD is activated by any type of non-energized switch closure that is connected to the signal input binding posts. The MULTIGUARD will identify the malfunctioning  equipment by transmitting a warbling alarm tone followed by a preset number of beeps on the page phone system.
