3. M1 INSTALLATION

STATUS
The M1 module controls all of the alarm reporting operations. An
exception exists following a system failure when the communication
modules change to autonomous mode and perform a basic callout (to
announce the system failure). Communications and power to the
expanders is taken through the mating connectors on the top and bottom of
the modules.
Connectors - Power and Signal
Refer to Figure 7 for details of the connector pinouts and Figure 8 for
details of the serial cable required for programming.
Power
Input voltage is connected to the M1 module only. Attach the ground
lead of the external supply to the GND terminal and the positive lead
to the +PWR terminal. Note that the chassis of the Link system is
connected to ground. The Link System requires a power supply
voltage of 10-30 VDC, 2.8A Max. The power supply used should be a
safety approved Class 2 power supply source, current limited using a
3A in-line slow-blow fuse.
Total system power will depend on the number and type of modules
that are in operation. Each module draws a maximum of 150 mA with
all indicators on. The W1 and W2 modules are exceptions drawing 300
mA and 650 mA respectively when transmitting at maximum power
and all indicators on.
Input power is monitored as an analog value by the M1 module and
can be programmed as an alarm.
Local Acknowledge Input
If an external acknowledge pushbutton is to be used with the system it
should be connected between the ACK terminal and ground; do not
apply voltage to the ACK input. The pushbutton must be a normally
open type. The circuit for ACK and PFAIL is shown in Figure 6.
