10 411UDAC Manual — P/N 51073:E 9/20/2013
Section 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, four-
wire smoke detectors, pull stations and other normally-open contact devices. The unit also super-
vises 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 Windows
®
-based remote site programming software. The 411UDAC is supplied with
a compact metal cabinet.
The digital communicator can be programmed or interrogated off-site via the public switched tele-
phone network. Any IBM compatible personal computer with Windows
® XP or greater, with a
1200 baud Hayes
®
compatible modem and Upload/Download software P/N PK-411UD, may serve
as a service terminal.
