Abstract:

Each thermostat as submitted was set up in this laboratory in a standard Navy fire alarm circuit and closely observed for accuracy of operation while under test for conformance with Navy Department Specifications SGS-(65)-25, modified by schedule 9947. The object of this test was to determine the suitability of the thermostats for fire alarm equipment for Naval vessels and compliance with Navy Department specifications. These thermostats as at present manufactured by the H.B. Instrument Company and covered by this report, are not considered satisfactory for installation in Naval fire alarm systems due to their failure to comply with the specifications.
