OUTPUT 1 (RELAY 1)
Output 1 is a Form C dry contact relay rated at 30 VDC. 0.5 A.
Output 1 activates (energizes) when the B465 is powered and the microprocessor is operating
correctly. If the microprocessor stops operating correctly or the B465 loses power, Ouput 1
de-energizes. The default output function is System Trouble. When the B465 has a system
trouble event Output 1 de-energizes.
Using the default output function, System Trouble, Output 1 can be used to indicate a system
trouble on one of the connected control panel's inputs (zone or point). Depending on the
configuration required to create a system trouble on the control panel, use either the NO and
COM or the NC and COM terminals on the B465. Refer to the control panel manual for the
required configuration to obtain the proper response.
OUTPUT 2 (RELAY 2)
Output 2 is a Form A dry contact relay rated at 30 VDC, 0.1 A.
RELAY 2 is a normally open (NO) relay with contacts that close when the output function runs.
The default output function is Primary Power Fail.
OUTPUT 3 (RELAY 3)
Output 3 is a Form A dry contact relay rated at 30 VDC, 0.1 A.
RELAY 2 is a normally open (NO) relay with contacts that close when the output function runs.
The default output function is Battery Fail.

Primary power source wiring

You can configure the B465 to use 24 VDC from a UL listed fire control panel or power supply
as the primary power source. The default configures the B465 to use AC as the primary power
source. You can use a D1640 plug-in transformer, D1640-CA plug-in transformer, or
D1640-120WI wired-in transformer. These transformers have a rating of 16.5 VAC, 40 VA.
Earth ground connection first
To help prevent damage from electrostatic discharges or other transient electrical surges,
connect the system to earth ground before making other connections. The earth ground icon
indentifies the earth ground terminal. Recommended earth ground references are a grounding
rod or a cold water pipe. Make the connection using 14 AWG (1.8 mm) to 16 AWG (1.5 mm)
wire.
AC operation
When the Primary Power Source is set to AC, the B465 makes an AC power failure event when
the voltage at the primary power (24 VDC or 16.5 VAC) terminals is not sufficient.
The Primary Power Fail Delay parameter sets the number of minutes without power before
B465 makes the AC power failure event. When power returns, the B465 uses the Primary
Power Fail Delay parameter to delay the AC power restoral event.
For example, if the Primary Power Fail Delay parameter is set to 60 minutes, the B465 waits
60 minutes before it makes an AC power failure event. After AC power restores, the B465
waits 60 minutes before it make a restoral event.
Follow the steps below to install the 16.5 VAC transformer as the primary power source.

Battery Trouble
ALL Comm Fails
Ethernet Comm Fail
Cellular Comm Fail
Use 18 AWG (1.02 mm) wire minimum (12 AWG [2 mm] maximum) to connect the
transformer to the control panel. Make the wire length as short as possible. Do not
exceed 50 ft. (15 m). Maximum wire resistance should not exceed 0.65 ohms.
Connect the wire to the control panel.
