2 DS9400M AddressiFire Fire Alarm Control Panel

Smoke detector alarm verification

Should an alarm occur, the DS9400M may be programmed to perform an automatic reset on the smoke detectors. If a second alarm on any smoke input point occurs within the verification window, an immediate fire alarm results. This reduces potential false alarms, while still providing fast response to an alarm.

Flexible digital communication

The communicator will work with most alarm receivers that are in use today. It supports SIA (110 or 300 Baud), Contact ID, BFSK, and 4/2 Tone burst digital communicator formats.

EE Memory

The panel uses EEPROM technology, thereby allowing it to retain all program memory through a total power failure. None of the system programming or user codes will be lost.

Three telephone numbers

The systems supports two 20-digit telephone numbers with a three- or four-digit account code for each. Each phone line’s dialing type can be configured for either pulse or tone dialing. The communication format for each phone number can also be set. The third phone number is reserved for remote programming.

Event history buffer

A 500 event history buffer, which can be read at the built-in or DS9447 keypads, keeps track of events by time and date.

Commercial Fire

Type Service: Auxiliary, Local, Central Station, and Remote

Station.

Type Initiating: Automatic, Manual, Sprinkler Supervisory

and Waterflow.

Installation/Configuration Notes

Keypads:

Up to four keypads may be used in the system with a maximum wire length of 300 m (1000 ft.) each.

Note	No more than two keypads per 300 m (1000 ft.)
	run.

Wiring:

The maximum wire length total in the system is 1220 m (4000 ft.) using 0.8 mm (#22 AWG) or 1.0 mm (#18 AWG) 4-conductor cable.
