Remote Inputs
The E-969 may be activated from two
remote inputs. The typical remote input
circuit is shown. A contact closure to
ground or a low sequence signal, capable
of sinking more than 5 mA, will activate the
E-969. The closure must remain active for
a minimum of 1/2 a second.
The remote input may be programmed two different ways. It may activate a predefined Call Key or it may
be set for an individual command and address.
Precheck
Precheck is a Whelen High Power Voice and Siren System function which allows the user some flexibility
in operating their warning system. Certain Whelen product, such as, the System Status Map, use the
Precheck digit to preview a command without actually activating any sirens. Refer to other Whelen product
manuals, or contact the factory, for additional information on the use of the Precheck function.
Note that in the E-969 Keypad Programming mode, the
PRECHECK
key acts like a personal computer
“Enter” button.
Programming
The E-969 encoder has eight call keys. Four of those call keys can be accessed from the “C” keys located
on the keypad (labeled C1, C2, C3 and C4). The other four call keys (C5, C6, C7 and C8) can only be
accessed by way of the two “Remote Inputs” and two “Time of Day” activations.
The intended use of a Call Key is to simplify and minimize the users time when siren system activation is
required.
Call Keys C1 – C4 require direct user selection. Once one of these keys is selected, the user must press
the “Send” button in order start the call key sequence of activations. This makes this a two button
operation.
The two “Remote Inputs” can be programmed for any one call key (C1, C2, C3, C4, C5, C6, C7 or C8).
Additionally, the “Remote Inputs” can be programmed as a “One Shot” single command activation without
the use of a call key. To initiate a “Remote Input” activation, a single momentary 500ms dry contact closure
must be made between the selected “Remote Input” and the E-969 ground point. This makes for a one
button operation. A remote momentary push button can be located away from the E-969. If this button will
be located in a different building away from the E-969, then an isolation relay should be used.
The two “Time of Day” functions can be programmed to activate any one call key (C1, C2, C3, C4, C5, C6,
C7 or C8). Additionally, the “Time of Day” functions can be programmed to activate a single command
without the use of a call key. The “Time of Day” Function can only be programmed for a repeating seven
day calendar.
