Instruction Manual of A9056T I/O Module
----- Please read this Manual carefully before installing and using the product. -----
I. Overview
The A9056T I/O module (A9056T for short) is used with SEC3002 fire alarm control panel. It is mainly
used to realize an output control for fire linkage equipment (such as smoke dampers, blow valves and
fire dampers) and receive the feedback signals of the fire linkage equipment so that a judgment on
whether or not the fire linkage equipment is operating normally can be done.
III. Feature and technical parameters
1. Executive standard: EN54-18
2.Operation voltage: loop DC24V (polarity-insensitive);power DC24V(polarity-insensitive)
3. Quiescent current: loop current
＜
0.8mA; power current<2mA
4. Action current: loop current
＜
5mA; power current<15mA
5.Capacity of the output control contact: 1A@DC30V
6.Operation indicator: The inspection indicator will blink once about every 12 seconds in the inspection
status or remain lit in the output status; the input indicator will remain lit in the feedback status.

Terminal description (see Fig.2)
Terminal Name
Function
D1,D2
DC24V power input, non-polarized
L1,L2
Loop connection, non-polarized
TO+,TO-
Voltage-free Input, factory default mode is normally open. For normally closed
mode, Jumper JP4(see Fig1)
’
s Pin1 & Pin2 should be shorted.
NO1,NO2
Normally open contact. For voltage output, NO1 and NO2 should be connected
with DC24V positive and DC24V negative respective.
NC1,NC2
Normally closed contact.
COM1,COM2
Common contact contact.When set to voltage output, the controlled equipment
should be connected between COM1 and COM2.

2. Jumper setting and wiring method
1) For normally close input,short JP4
’
s Pin 1 & Pin2; for normally open input,short JP4
’
s Pin 2 & Pin3.
2) For project application, Jumper JP1,JP2,JP3
’
s Pin1 & Pin2 should be shorted(Pin2 & Pin3 are shorted
as factory default , only for production test) .
3) The ends of input and output circuit should correctly use a 47K
Ω
resistor (shown in Fig. 3) , so that the
I/O module can identify the short-circuit fault or open-circuit fault of the input and the output circuit.
4) For voltage output, NO1 and NO2 should be connected with DC24V positive and DC24V negative
