Valcom Failsafe Unit
1. - Introduction
Congratulations on the purchase of the
Valcom Failsafe unit, Series1620E-24VDC
this unit
was designed specifically for your System. Please follow the instructions outlined on these next
few pages to put your system on line.
In general a UPS (Uninterrupted Power Supply) or Failsafe unit delivers emergency power in the
event of regular source power failure or interruption. This Failsafe unit was designed to open or
close one or more actuators after a power failure, if more than one actuator is to be controlled by
this system the unit will remain ON until the last controlled actuator has reached the failsafe
position.
Your Failsafe unit is housed in a NEMA Enclosure, and is shipped with two complete sets of
drawings one set has been attached to the inside door and an extra set is supplied for your files.
Your Fail-safe unit features sophisticated electronic circuitry. It provides high peak power output
to start and run devices requiring high current for short duration. This high current is referred to
as
locked rotor amperage
. Once interfaced with your system, the unit will operate
automatically during power failure.
2. - Unpacking the Failsafe unit
Upon receiving your Failsafe unit, you should check the contents of your package. First inspect
the shipping container for any indications of mishandling. If there is any evidence of damage to
the container you should report it to your carrier, a representative of Valcom, or to Valcom
directly. Next inspect the control cabinet and the internal controls and if anything appears to be
abnormal or damaged report it at once.
