Caution!
Do not short-circuit the terminals of the plug-in transformer
!
Shorting the terminals causes permanent failure. Connect the plug-in transformer to the 16.5
VAC terminals of the B465 before plugging it into the power source.
Notice!
AC wiring can induce noise and low level voltage into adjacent wiring
Route telephone and input loop wiring away from any AC conductors, including the
transformer wire.
Notice!
Commercial Fire requirement
Commercial Fire application require that you install a D8004 Transformer Enclosure if you are
using either the D1640 or D1640-CA plug-in transformers.
DC operation
When the Primary Power Source is set to DC, the B465 makes a DC power failure event when
the voltage at the primary power (24 VDC or 16.5 VAC) terminals is not sufficient, or when the
polarity of the DC power source is reversed.
The Primary Power Fail Delay parameter sets the number of minutes without power before
B465 makes the DC power failure event. When power returns, the B465 uses the Primary
Power Fail Delay parameter to delay the DC power restoral event.
For example, if the Primary Power Fail Delay parameter is set to 3 minutes, the B465 waits 3
minutes before it makes a DC power failure event. After DC power restores, the B465 waits 3
minutes before it make a restoral event.
Install the negative voltage lead on the leftmost terminal. Install the positive voltage lead on
the terminal beween the the negative lead and the earth ground terminal.
Bosch Security Systems, Inc.
Connect the wire to the transformer.
Plug the transformer into an unswitched, 120 VAC, 60 Hz power outlet only.
