Heritage Med Call, Inc. in Tampa, Florida, US (United States)

HM-535 is a regulated DC power supply to provide low voltage to Sentry components. An external battery connects to supply voltage in the event of a power outage. 

UL listed fire, burglar and access control power supply (UL1481, UL603, UL294). NYC Department of Buildings Approved (MEA). 

INTELLIGENT POWER SUPPLY The Sentry System residences and common areas are powered by intelligent power supplies. During a power failure, the supplies are supported by batteries that are automatically charged when the power is restored. 

When possible, the power supply should be connected to the facilities emergency power to allow system operation for extended periods of commercial power outages. 

The Sentry Model HM-610 Utility Input Panel will monitor up to 12 separate contacts for indication on the Sentry Master Console. The twelve inputs can be wired to any remote, normally opened, normally closed, or open collector output device.
