Multi-Station Relay Adapters For

DASDEC™
EAS Encoder-Decoders

MSRA MSRA-RM

The Multi Station Relay Adapters (MSRA & MSRA-RM) are a microprocessor based, three stereo channel accessory for the DASDEC™ EAS/CAP encoder-decoder, allowing a single unit to expand the number of individually controlled stations from a one to up to a total of four. All commands and EAS audio are supplied by the DASDEC™, and the MSRA interprets these commands to select the appropriate station (or stations) for EAS broadcast.

The MSRA is compatible with all of the DASDEC™ models with the appropriate software upgrade (V2.5-x or higher). The required DASDEC™ upgrade is available on a limited basis until the next full system release. The upgrade is free for registered DASDEC™ users who have installed a Plus Package, or MultiStation™-2 or MultiStation™-5 keys to their systems. More information about the required upgrade is available from the factory at sales@digitalalertsystems.com, or by calling Digital Alert Systems at 585-765-1155.

The MSRA connects to the DASDEC™ rear panel via the supplied RS232/audio cable along with the EAS audio from the “Auxiliary Audio Output” connection. The MSRA provides a multi-turn recessed front panel “ Input Gain” trim potentiometer and multi-turn individual “Station Gain” controls for controlling the active stereo distribution amplifier sections with balanced output levels capable of greater than +12dBm into a 600 ohm load impedance. A recessed front panel “Test” switch provides a handy aid for setting audio levels.

An optically isolated open collector “Tally” output for user control applications is provided and is active when any or all of the 3 MSRA controlled stations are activated, and remains active until the end of the EAS activation.

The MSRA is transparent to program audio due to it’s loop-through design, and uses 6 high quality bifurcated gold over silver nickel contact sealed relays, one relay for each left and each right channel circuit. The MSRA also is designed to remain transparent to program audio during any power failure condition.

All station inputs and outputs are connected using large 5mm Eurostyle screw type pluggable connectors for wiring ease and connection reliability. The internal power supplies, precision regulators, precision audio distribution amplifier sections and quality components throughout assure long life and trouble free operation of the MSRA. No external power supplies (wall warts) are required. Front panel LED indicators are provided for “Power” and “Station” left and right audio relay activation during an EAS event.

Both 2U rack mount systems (MSRA-RM) and table top units (MSRA) are available.

For units providing activation of relay contacts only for control of AES and Ethernet switchers or routers please check out the Multi-Station Expander (MSRE) below.

Multi-Station Relay Expander
for control of AES or Ethernet Switches
and Routers

for the DASDEC™
EAS Encoder-Decoder

MSRE
MSRE-RM

The Multi Station Relay Expander (MSRE & MSRE-RM) is a microprocessor based, six form "C" relay output accessory for the DASDEC™/CAP EAS encoder-decoder. Primarily designed to control AES Digital Routing Switches and Ethernet Switches or Routers for digital audio control from your DASDEC™, and expands the number of individually controlled stations from a single DASDEC™ to up to a total of four stations. While there are two relays for each station assignment, they may be programmed to operate individually if desired. The DASDEC™ and MSRE work together to select the appropriate relays for control of the external switching or routing devices.

The MSRE is compatible with all of the DASDEC™ models with the appropriate software (V2.5-x or higher). The required DASDEC™ upgrade is available on a limited basis until the next full system release. The upgrade is free for registered DASDEC™ users who have installed a Plus Package, or MultiStation™-2 or MultiStation™-5 keys to their systems. More information about the required upgrade is available from the factory at sales@digitalalertsystems.com, or by calling Digital Alert Systems at 585-765-1155.

The MSRE connects to the DASDEC™ rear panel via a supplied RS232 cable. A recessed front panel “Test” switch provides a handy aid for system setup and testing.

The MSRE uses 6 high quality bifurcated gold over silver nickel contact sealed relays, one relay for each left and each right channel circuit, and is also designed to remain transparent during any power failure condition.

All outputs are connected using large 5mm Eurostyle screw type pluggable connectors for wiring ease and connection reliability. Included are a 9VDC 500Ma power module, a 7' Data cable, and rack mounting screws for the MSRE-RM.

F
ront panel LED indicators are provided for “Power” and “Station” left and right relay activation during an EAS event.

1U rack mount systems (MSRE-RM) and table top units (MSRE) are both available.
