Control Panel Features
The control panels benefit from the following features.
Network Ports
The network ports enable additional devices to be connected to the control panel for system
expansion. The number of networks and the devices available for networking depend on the
control panel used.
Transistor Outputs
Each control panel contains programmable transistor outputs, which provide control for
external equipment:
Depending on panel type, one or two outputs are switched negative. These switch from
12Vdc to 0V on activation, and in this mode can sink up to 500mA from a 12Vdc source.
One output is switched positive. This switches from 0V to 12Vdc on activation, and can
deliver up to 500mA to an external load.
Relay Outputs
Relay outputs provide voltage-free changeover contacts, which can be programmed to
switch external equipment on or off. Depending on panel type, there are one or two relay
outputs.
Digital Communicator Outputs
These outputs are normally connected to a digital communicator – a device that transmits the
status of each output to an Alarm Receiving Centre. The panel provides 8 or 16
programmable outputs, depending on panel type. Each output can be programmed as
required, e.g. to indicate a zone alarm.
If required, the outputs may alternatively be used to drive low-power devices such as LEDs.
By default, each output is switched negative, i.e. normally at +12Vdc and switches to 0V
when active. When at 0V, up to 100mA can flow into the output from an external source.
If required, the sense can be reversed during system configuration, i.e. normally at +0V and
switches to 12Vdc when active. In this case, when switching to +12Vdc, each output can
deliver up to 5mA to an external load.
USB and Serial PC Ports
Optionally, a PC running the Downloader software can be connected to the control panel for
system configuration and data uploading. The PC can connect to the panel's USB port, or
optionally on an M1000, via the Serial (RS232) port.
On-Board Modem
On all models except the M550 and M750, an on-board modem allows the control panel to
be connected to a remote PC running the Downloader software, and alarm status information
to be transmitted to an Alarm Receiving Centre (ARC).
The control panel can be easily connected to the telephone network using the on-board RJ11
telecom socket. Alternatively, a PSTN terminal block is provided for optional wired connection.
