The module may be switched into either mode and back again (as many times as desired) independent of which
mode it was initiated.
Recommended setting for SW3 is OFF.
______________________________________________________________________
SW4:
ON = Activate the system from ring detector.
(Note: system will also activate with trigger input when in this position, dependent on SW5.)
OFF = Activate the system with the trigger input ONLY (disable ring detector).
This switch controls the full-time ring detector. It DOES NOT control the "5-minute window after alarm activation" ring
detector. These are two separate modes and controlled separately.
If it is desired to have the system activate the ring detector, place this switch in the ON position.
If it is desired to have the system activate ONLY with the trigger input, then place the switch in the OFF position.
Recommended setting for SW4 is OFF.
_________________________________________________________________
SW5:
ON = Activate immediately with the trigger input (Line-hold mode).
OFF = Set up the ring detector to answer after one ring.
When SW5 is in the ON position, the system will activate immediately with the trigger input. (This occurs when the
digital communicator is shut down with a kiss-off from the Central Station.) A trip from the communicator/control
panel or an Eagle Model 1405 or 1406 activation module is required.
When SW5 is in the OFF position a trigger input will activate a five (5) minute window. The 1241 will answer the
phone line as soon as it sees one ring within this window. The system will ignore any invalid phone calls (see section
4.2). When the five minute window expires, the system will ignore any additional phone calls (unless programmed for
"call-back" mode with SW4).
Recommended setting for SW5 is ON.
________________________________________________________________
SW6:
ON = Positive edge trigger on trigger input.
OFF = Negative edge trigger on trigger input.
When SW6 is in the OFF position, the system will interface with digital communicators that provide a trigger input that
is at 1.5 VDC or less when NOT reporting and switch to 2.5 VDC or greater when reporting.
When SW6 is in the ON position, the system will interface with digital communicators that provide a trigger input that
is at 2.5 VDC or greater when NOT reporting and switch to 1.5 VDC or less when reporting.
SW6 is installation dependent. There is no recommended setting.
NOTE: This mode is independent of the full-time call back mode. If it is desired that the only time
the module is to answer is when the ring detector has been set up with the trigger input,
set SW4 OFF (trigger only).
NOTE: Before selecting this option, determine which type of trip will be used by measuring the DC
voltage at the trigger input when connected to the communicator. (Positive lead of the voltmeter
on Terminal TRIP of the 1241, negative lead of the voltmeter on Terminal GND on the 1241.)
