The Simplex 2004FS fire alarm control unit (FACU) delivers flexible initiating circuit monitoring for areas requiring one to four initiating zones. Figure 1: 2004FS FACU

The DACT must be electrically in series with, and ahead of, all other equipment attached to the same telephone line. Proper installation is depicted in Figure 1.

DACT (digital alarm communicator transmitter)-— Provides transmis- sion through phone lines to a monitoring station. Digital alarm radio system (DARS) — Sends a radio signal from a digital radio transmitter located at the protected premises to a monitoring station.

The 2250FS is an addressable 250 point fire alarm control unit (FACU) that is suitable for both new and retrofit applications. Duct detector. Available in the future. Reports up to ten events …

Use the built-in Digital Alarm Communications Transmitter (DACT) for remote station or central station monitoring.

The SA-DACT transmits system status changes (events) to compatible digital alarm communicator receivers over the public switched telephone network. The SA-DACT queues messages and transmits them based on priority (alarm, supervisory, trouble, disable, test, monitor, and system).

Fire alarm control unit (FACU) is powered up and clear of alarms, supervisory signals, and trouble conditions. Have ground fault put on any alarm initiating or notification appliance (horn-strobe) circuit.
