Activation
The IN1 and IN2 terminals are used to activate the system. The triggering polarity for each
input is independently selectable. It can be triggered by a voltage input or by a relay contact.
When a relay contact is used, it is used to apply a voltage to an input.
A positive voltage terminal is provided next to each input. When positive triggering is
selected, a normally open relay contact can be connected between an input and the
adjacent positive terminal. When the contact closes, the input voltage rises and the system
triggers. A normally closed contact can be used by selecting the negative triggering polarity.
When the contact opens, the voltage at the input drops and triggers the system.
Armed status input
The armed status of the control panel which is used with the Informa 300 can be determined
when the system is remotely interrogated. The armed status output from the control panel
is connected to the ARM IN terminal of the Informa 300. Either positive or negative arming
can be used. The polarity is selected during option programming.
Status outputs
The status outputs are driven by open collectors. They can be used to drive relays or they
can supply a logic voltage when used with pull-up resistors. When active, these outputs
pull low; they act like closed switches to ground. To drive a relay, one end of the relay coil
connects to a positive DC voltage; the voltage depends on the relay specifications. The
other end connects to a status output. The relay is energized when that status output is
active.
– CALL OK
Indicates at least one call was completed successfully.
– LINE FAIL
No voltage on the phone line possibly due to a break.
– COM FAIL
At least 1 call was unable to be completed.
– LOW BAT
Battery voltage (power supply) is below 85% of nominal.
– COM ON
The communicator is currently sending messages.
– PRG 1 & 2
Programmable outputs, used with optional beeper decoder.
Speaker
The speaker is used to listen to the recorded messages. When the 2-Way Voice board is
installed, it is also used with the microphone to allow the called party to converse with a
person near the Informa 300.
