AMX Radia RE-DM6, Operation/Reference Manual

Page: 35 / 104

Installation
29 RE-DM4 and RE-DM6 RADIA Eclipse Dimmer Modules
Dry Closures
The RE-DM4 and RE-DM6 have two dry closure inputs via a 4-pin mini-phoenix connector. The inputs
are an open collector pulled up to 5 VDC. The status is normally open, channel Off, with the closure
released. When an input is pulled low to ground and falls below 3 VDC, the AMX Lighting system sees
the action as an input closure, the AXLink channel is turned On, and a push sent to the Axcess Central
Controller.
Connecting dry closures
AMX Lighting controller modules contain four connections for two dry contact closure inputs, and one
common reference point. The Radia has two (2) contact closure inputs dedicated to special purposes:
Failsafe and Emergency.
Failsafe Input
The failsafe input is provided to facilitate limited stand-alone operation in the event that the AXLink
master is no longer functioning. The failsafe input shall function regardless of whether AXLink is
working properly or not (i.e. there is no lockout of control).
Operationally, when the failsafe input contact closure is closed (i.e. ON), preset 128 will be recalled.
When the failsafe input contact closure is opened, preset 127 will be recalled. Both of these preset recalls
occur on the edge of the transition from opened-to-closed to closed-to-opened.
Emergency Input
The emergency input is provided to interface to an alarm system (such as a fire alarm) to set the lighting
to an appropriate state for an emergency (e.g. light the path to the exit). The expected operation of the
alarm system is to hold (close) the contact closure as long as the alarm is active and release (open) the
closure when the alarm is cleared.
Operationally, when the emergency input contact closure is closed (i.e. ON), preset 126 will be recalled.
In addition, all other controls of the lighting functions will be disabled as long as the emergency input is
closed. When the emergency input contact closure is opened, normal operation of the Radia will resume.
