5.11.3.1 The Expansion
By referring to the Figure 54 - AS500/RPT Board, the functions of the terminals, LEDs, and buttons dedicated to the Expansion are the
following:
Terminal board
Group
Description
Connection / Function
M1
Bus IN
+
Expansion power supply via bus
+D
BUS Data transmission/reception
D
─
Expansion power supply via bus
M2
Outputs
+V1
Power supply for output actuators (limited to 500 mA)
-V1
NC1
Relay output 1 – contact normally closed
NO1
Relay output 1 – contact normally open
C1
Relay output 1 – common (max. 1 A - 24 V⎓)
U2
Electric output 2 can be configured
(protected from short circuit - I max 10mA)
U3
Electric output 3 can be configured
(protected from short circuit - I max 10mA)
M3 / M4
Inputs
+V2
Power supply for detectors (limited to 500 mA)
-V2
IN1
Alarm input n. 1
IN2
Alarm input n. 2
IN3
Alarm input n. 3
IN4
Alarm input n. 4
IN5
Alarm input n. 5
IN6
Alarm input n. 6
IN7
Alarm input n. 7
IN8
Alarm input n. 8
SAB
24h input (for system self-protection), must always be
BALANCED and closed with a 15 kΩ balancing
resistor.
TAMPER
Tamper
Connector for connection of the tamper
JP1
Jumper for the exclusion of the tamper
(Jumper inserted = tamper excluded)
PROG
Button and
LED
Button and LED (yellow) for programming.
RUN
LED
Green LED to signal operation.
The electric outputs U2 and U3 can be individually configured as “positive reference” or “negative reference” via the JP2, and JP3
jumpers. The default configuration of the outputs is “Positive Reference”.
The electric outputs can be transformed into relay outputs – See Paragraph 5.12.6.2.
For details on connections (power supplies, inputs, outputs, bus, etc. …) see paragraph 5.12.2 Connecting the data Bus and
paragraphs 5.12.5 Connecting inputs and 5.12.6 Connecting outputs.
The expansion is always powered by the control panel via the bus connected to the M1 terminals. The power supply for the detectors
and the signalling devices connected to the M2 / M3 / M4 terminal boards always arrives from the control panel.
The expansion section also controls the functioning of the secondary bus. If an attempted tampering should be detected or merely a
malfunction should be detected, disconnect the secondary bus to prevent compromising the functioning of the entire system.
The MP500/8 or MP500/16 control panels receive information on the functioning of the supplementary power supply from the
expansion: black out, battery low, and power supply breakdown.
