4.2 Use of input terminals
4.2.1 Input terminals on the master control board
Fig.4.1.1 Input Terminals on the Master Control Board
Purposes of the input terminals on the master control board:
No. Purpose
16 +24VK
17 Input of the MANUAL RELEASE button
18 Input of the MANUAL FIRE ALARM button
19 Input of the PAUSE switch
20 Input of the MANUAL/AUTO switch
21 Input of the MUTE button
22 Input of the RESET button
23 Pressure feedback input terminal for release confirmation
24 Input terminal for agent drop alarm
25 Input terminal of the second detection and alarm circuit
26 Input terminal of the first detection and alarm circuit
Note: It is not allowed to share the input circuit ground and the output circuit ground. The +24V
PGND has been connected with the output circuit ground in the control board.
4.2.2 Connection modes of input terminals
The local input signals include three kinds, namely that for the AGND short/open circuit switch, that for
the +24V short/open circuit switch and that for the detector circuits. The connection modes of the input
signals of different kinds are given in the table below.
