Installation and use MR16
Connecting inputs
Radio module MR16 is provided with inputs through which it can learn wired system status and receive
commands from the system. Input polarity (reference to either positive or negative polarisation) is defined
by DIP switch B6 (see paragraph
4.1.4 Configuration of radio module MR16
).
Below table shows connections to be made:
Input Description
S
This input must be connected to an output of wired control panel which follows
control panel status.
The value of voltage depends on input polarity chosen:
•
positive polarity
(DIP switch B6 = ON): by applying 12 V voltage, the module, if
armed, is disarmed; taking off the voltage, the module, if disarmed, is armed.
•
negative polarity
(DIP switch B6 = OFF): by applying 0 V voltage, the module, if
armed, is disarmed; taking off the voltage, the module, if disarmed, is armed.
BL
This input is used to drive wireless sirens, by acknowledging a voltage at its pin.
This input must be connected to an output of wired control panel which is armed
when the sirens are armed. By applying 12 V voltage to the pin, radio sirens are
silenced; taking off the voltage, the sirens ring.
