56 Installation—Installing the FC-2000
The 911A Digital Alarm Communicator Transmitter (DACT ) is a
3-channel digital communicator designed to provide off-premises
monitoring of a fire alarm control panel. For standalone application, use
the 911AC kit that includes a transformer and enclosure(s) for both the
911A and the transformer. The 911A is triggered by the alarm, trouble
and/or supervisory contacts received from the control panel and converts
them into digital transmission format. It communicates with a digital
receiver by means of one of two transmission formats; BFSK or Pulsed
Fast Single Round.
Install the 911A Digital Communicator in accordance with the 911A
Installation Manual, shipped with the 911A. Connections between the
control panel and the digital communicator are illustrated in Figure 40.
Power Requirements:
● 26 VDC, 30 mA in Normal
● 138 mA while communicating
● 166.8 mA with alarm and trouble relays while communicating
Retard time and Reset time must be programmed for zero seconds when
connecting the alarm initiating circuit to an existing control panel.
For more detailed instructions refer to the 911A Installation Manual.
Note: The 911A is not FM-approved.
