CHAPTER 1 Product Description
The 411 is a three input/channel, dual line, digital alarm communicator transmitter which can be used as a slave com-
municator with UL listed fire and nonfire control panels. The three inputs are compatible with normally open relay
contacts, require End-Of-Line (EOL) resistors, are supervised and are fully programmable. The 411 interfaces with
the public switched telephone network and is compatible with most central station receivers. A total of fifteen popu-
lar communications formats are supported, including Ademco Contact ID. The communicator also contains a unique
DACT option that eliminates 'dialer runaway'. It restricts the transmission of any trouble event to 10 attempts in a 24
hour period. Power supplied must be 12 or 24 volts, filtered and nonresettable. The Fire-Watch 411 Series DACT
Programmer is available for 411 programming. The 411 comes in a small 6.841" (17.376 cm) X 4.595" (11.671 cm)
X 1.00" (2.54 cm) metal enclosure, providing a variety of mounting options.
