Input Channels

2.3 Input Channels
The 411/411UD digital communicator has three (411) or four (411UD) channel inputs. Each chan-
nel is a Style B (Class B) Initiating Device Circuit designed to accept any normally-open contact
device. Since channels do not latch, a reset switch is not provided by the 411/411UD. The commu-
nicator transmissions to a central station track the state of the inputs. Refer to Figure 2.2, "Style B
Channel Connections" on page 18 for information on wiring Style B circuits.
Note: The monitor module input, which is being
used to monitor the 411/411UD Relay Output
(programmed for DACT Trouble), must be
programmed as 'DACT Trouble' at the FACP

Each input channel monitors a normally open device and may be programmed as follows:
• fire alarm
• host control panel trouble
• fire supervisory
• AC Loss
Programming the input channel automatically programs the transmitted event code, however, the
event code can be changed since it is fully programmable. Event code transmissions can be tailored
to the specific application and requirements of the Central Station.
AC Loss Reporting - 411: Any channel programmed for AC Loss, will transmit a specific AC loss
signal only if the assigned Normally Open contact provides this function. Some panels provide an
option that will automatically delay the trigger of their system trouble relays upon loss of AC. If
this is provided by the host panel, program no additional delay in the 411. Be certain to verify the
method employed by the host panel to be monitored.
AC Loss Reporting - 411UD: Channel 4 which is defaulted to AC Loss on the 411UD, or any chan-
nel programmed for AC Loss, will transmit a specific AC loss signal only if the assigned Normally
Open contact provides this function. Some panels provide an option that will automatically delay
the trigger of their system trouble relays upon loss of AC. If this is provided by the host panel, use
Channel 2. Be certain to verify the method employed by the host panel to be monitored.
