GENERAL DESCRIPTION
The input/output unit is designed to control and receive information from external devices for the fire
alarm system IFS 7000 in case of detecting fire conditions.
The input/output unit (fig.1) consists of a printed circuit board (pos.2) and an unit carrier (pos.4), fixed
in a plastic box with bottom (pos.1) and a cover (pos.3). The terminals for connecting the signal loop SL
(pos.3), the power loop PL (pos.4), potential free relay outputs OUT2, OUT3, OUT4, OUT5-1, OUT5-2
(pos.1), the controllable output OUT1 (pos.6), the inputs separated by means of electroplating IN1, IN2,
IN3 (pos.2) and constant current supply output 24VDC (pos.7) are located on the printed circuit board
(fig.2). Outputs OUT5-1 and OUT5-2 are switched over simultaneously and are controlled by one relay.
The unit is completed by terminating resistor R (pos.5) with value 5ê6.
The communication between the Fire Control Panel IFS 7002 and the input/output unit is completed
via the signal loop by the specialized data exchange protocol UniTALK. The input/output unit is power
supplied simultaneously by the power and the signal loops. Two built-in isolators are provided for short
circuit protection - one on the signal loop and one on the power loop.
