Test mode: Dialling FF (hex) on the code switches and pressing “Reset” enables a test mode where the red “OFF” LED
shows the PIR input state, and the Green LED above it (normally On or Video) follows the Aux input state. As you
walk around the room, the LED shows the area covered, and the mount angles can be adjusted to the normally occupied
area.
Note: This function can be used without the PIR, just as an OFF-timer. When the timer is about the close the
system down, the current channel LED and the OFF LED flash alternately for 30 seconds before closedown.
Pressing the current channel key will cancel the timer and restore operation for a further timer preset period. If
using without a PIR, the PIR screw terminal must be shorted to the Gnd screw terminal via a short piece of wire.
OPT3: AUX/PIR input for remote enable/start/stop mode setting for key/timer/PIR in
There is a number stored in Constant:C which is used to determine the mode for external control inputs into
Connector J3’s Aux input is for auxiliary inputs, e.g. a card swipe reader, key switch, a programmable timer or a simple
“Push-to-start” customer push button for system enabling or starting (and optionally, stopping) Constant:C also controls
use of the PIR input to Connector J3 to automatically start projector operation (and optionally continue it, if there are
repeated PIR pulses).
NOTE: These functions are only enabled when OPT3 switch is turned ON.
If this switch is turned OFF, the T440 ON keys(s) can be used, allowing easy setup of default channels and other
testing. Then turn OPT3 switch ON to engage these control functions (and disable the ON key(s)). After an Aux/PIR
initiated turn-on, the starting channel is the saved, (last used) one before turnoff.
The value set into Constant:C determines these remote enabling and control functions (only with OPT3 = ON):
•Constant:C = 00: (Default): Switch-ON mode, either a keyboard ON key or an external push button to AUX:
This modes allows an external contact closure wired into the J3:AUX terminal to operate exactly the same as
pressing the “ON” keyboard key. This could be a customer “Push-to-start-show” switch.
The projector turns OFF when either the OFF button is pressed or, if used, the PIR and the internal Closedown
timer (set at Constant:8) times out.
•Constant:C = 01: Switch-ON/OFF mode, either keyboard ON/OFF keys or external push buttons to AUX
and PIR: Same as 00 above, except OFF can be either keyboard OFF key or contact close on PIR input;
•Constant:C = 02: Switch-ON mode, no keyboard ON allowed (eg security card reader):
This modes allows an external contact closure wired into the J3:AUX terminal to operate exactly the same as
pressing the “ON” keyboard key. This could be a customer “Push-to-start-show” switch, a contact closure from a
RFID, a Swipe-card reader or a Dallas security key/button scanner or a key-operated switch (in the mode where
operating the switch momentarily “ON” starts the projector. (Input sources can be changed on the keyboard when
the projector is running.)
The key/switch input can be turned OFF and removed and the projector does NOT turn OFF immediately, in this
mode. The projector turns OFF when either the OFF button is pressed or, if used, the PIR and the internal
Closedown timer (set at Constant:8) times out;
•Constant:C = 03: Switch-Enable mode: This mode allows an external contact closure wired into the J3:AUX
terminal to ENABLE the “ON” keyboard button(s). (The J3:AUX contact can be turned OFF after the ON button(s)
press, (i.e. the external key can be turned OFF and removed) and the projector does NOT turn OFF immediately in
this mode.) The OFF LED blinks off momentarily every 5 seconds in this mode while disabled, and has no blinks
in the enabled state.
The key/switch input can be turned OFF and removed and the projector does NOT turn OFF immediately, in this
mode. The projector turns OFF when either the OFF button is pressed or, if used, the PIR and the internal
Closedown timer (set at Constant:8) times out;
•Constant:C = 04: Switch/Timer On/Off mode: This mode controls both the ON and the OFF from the J3:AUX
terminal. Typically this allows a remote switch (e.g. the output contact of a small LCD timer such as the JED
“460-Timer-12V” unit) or an external ON/OFF switch to control the whole ON and OFF operation, not just the
ON function. The PIR input and the internal Closedown timer does NOT operate in this mode.
The T440 keyboard is still operational (even with OPT3 ON), so pressing ON in the OFF-state will turn the
projector ON manually, and the OFF key will turn it OFF manually. If a programmed ON cycle occurs when it is
already ON, it remains ON, but will turn OFF automatically if the timer turns it OFF before it is manually turned
OFF. If the timer had turned it ON, the OFF key will turn it OFF, terminating a cycle. It will stay OFF until the
