Test mode 2 (t2) Force alarms over secondary path.
For test purposes an installer can set the unit to send all alarms over the secondary path. This
is achieved by accessing the t2 menu and setting the value to 1. There is no need to save the
change on the unit, simply use the Set (S) button to toggle the t2 value to 1 and then press
mode (M) to return to the t2 main menu option. Test mode 2 is now active and all new alarms
will be sent over PSTN on a PSTN/GPRS configured unit, or GPRS on an IP/GPRS configured
unit.
When test mode 2 is on, then incoming polls on the disabled path will still be responded to by
the unit. Therefore the platform will not normally report a communications failure because of
test mode 2 being active.
Test mode 2 will automatically exit after 20 minutes.
Test mode 2 can manually be set back to 0 (off) at any time by the installer.
At any time the configuration mode can be exited by holding down M for 5 seconds.
Example – to set test mode 2 on. All alarms sent over secondary path:-
Access the button config menu by holding M for 3 seconds.
Repeatedly Press M until t2 is displayed.
Press S – the display now shows the current t2 state. Where =0 is Off, and =1 is On.
Press S to toggle the mode off and on. Where =0 is Off, and =1 is On.
Press M to return to the t2 menu. (The test mode is now active)
At any time the configuration mode can be exited by holding down M for 5 seconds.
Pin Polarity (P1 & P2)
The polarity of the pins can manually be configured by the installer. This is additional to the pin
learn function described earlier. (P1 = pins 1 to 8 and P2 = pins 9 to 16)
By accessing the config menu by holding (M) for 3 seconds, and then stepping with (M) to the
P1 menu option, pressing set will enter the pin 1-8 sub menu.
Polarity of pin 1 is displayed, and can be toggled with the (S) button.
Further presses of (M) will step through all pins 1-8 showing their current polarity and allowing
each to be toggled to pos applied or pos removed with the (S) button. Once all 8 pins are set
as desired then (M) will return to the main menu (P1). Note that any changes are not saved
until the ?? option is accessed and (S) is pressed twice.
Pins 9 – 16 can be checked or changed in a similar way be accessing the P2 menu.
Note that the dot on the left display is on to distinguish pins 9-16 from 1-8. i.e. P2 menu has
the left dot lit, while the P1 menu does not.
The unit will reboot after the changes are saved at the ?? menu.
