Input Type
The Input Type setting determines a key difference between the EMS acting as a pedestrian crosswalk system, a
24/7 flasher or a school zone flasher. Set Input Type according to the following options:
For RRFBs and crosswalk beacons, use the input type
bttn
(button) only. All other
options are non-compliant and not to be used.
“Pushbutton.” Used for pedestrian crosswalks (R920, R820). A pushbutton is wired to the
pushbutton input terminals of the EMS, and when the button is pushed, a momentary short-
circuit across the input terminals occurs, causing the fixtures to flash for the duration set in the
“Duration” setting. Carmanah default.
“Normally Open.” Used for School Zone Flashers (R829) or any application where the flashers
must activate on demand. The usual state of the pushbutton input terminals is to be open and
not have a short-circuit across them. While the terminals are open, fixtures do not flash. If a
short-circuit is applied across the terminals - provided by a time switch, override switch, or some
other device - the fixtures will begin to flash and will continue to flash for as long as the short-
circuit is applied.
“Normally Closed.” Used for 24/7 flashers (R247). The flashers will flash continuously, day and
night, unless a short-circuit is applied to the pushbutton input terminals. The override switch can
be used to turn the beacons off by short-circuiting the button input terminals.
“Dusk-to-Dawn.” Used for 24-hour beacon systems that are intended to flash (continuously) only
at night. This is controlled via a system-integrated ambient brightness sensor. Ambient light
levels are detected via a clear cover on the top of the solar engine.
If radio-enabled systems configured with different input types are within communication range of
one another, radio channel settings should be set appropriately to avoid unintended operation.
See Radio Channel section.
