Description

This is a pre-owned Fire Watch 411UD 4 Channel Digital Alarm Communicator Transmitter in great condition. This was removed from a working environment where it was working properly.

The 411UD is a four input/channel, dual line, digital communicator which can be used as a slave communicator with UL listed fire and non-fire control panels.

The 411UD interface with the public switched telephone network and is compatible with most central station receivers. A total of fifteen popular 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.

Cost effective solution for applications that require a Fire Alarm control panel to transmit system status to an offsite monitoring facility for central or Remote Station compliance.
