Input Channels

411UD Document #50759 Rev. E 12/09/2008 P/N 50759:E
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: Channel 4, which is defaulted to 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 cer-
tain to verify the method employed by the host panel to be monitored.
The factory default programming for each channel is as follows:
Channel 1 - fire alarm
Channel 2 - host control panel trouble
Channel 3 - fire supervisory
Channel 4 - AC Loss
