Product Description
CHAPTER 1 Product Description
The 411UDAC is a fire alarm communicator with four input/channels and dual telephone lines. The four inputs use
conventional input devices. The 411UDAC accepts waterflow devices, two-wire smoke detectors, four-wire smoke
detectors, pull stations and other normally-open contact devices. The unit also supervises AC voltage, telephone line
input voltage/current, battery level and battery charger operation.
Outputs include one supplementary NAC (Notification Appliance Circuit), two programmable Form-C relays and 12
VDC resettable special application power. The 411UDAC interfaces with the public switched telephone network and
is compatible with most central station receivers. A total of fifteen popular communications formats are supported,
including the industry standard Ademco Contact ID. The communicator also contains a unique DACT option that
eliminates 'dialer runaway'. It restricts the transmission of any intermittent nuisance fault to 10 attempts in a 24 hour
period.
Accessories include the Fire-Watch 411 Series DACT Programmer (Model PRO-411) as well as the PK-411UD
