  Linear Supervised 8-Channel Solid State Relay Receiver DXSR-1508 | | Linear Supervised 8-Channel Solid State Relay Receiver DXSR-1508The Model DXSR-1508 Supervised 8-Channel Receiver is a eight channel supervised digital receiver with solid state outputs designed for use
with Linear's DX and DXS Format transmitters. This receiver can be used in a variety of security and remote control applications. When the
receiver detects a signal from a transmitter programmed into its memory, the appropriate channel output activates. The channel outputs have
three optional configurations; momentary, toggle on/off, and latch until restored. Status and low battery outputs are for supervisory
indications. Cutting jumpers select which channels require supervisory status reports from transmitters.
The Model DXSR-1508
incorporates a dual high-sensitivity superheterodyne diversity receiver with two whip antennas. This type of receiver provides superior
performance by preventing loss of signal due to multi-path interference.
In a typical installation, the receiver is connected to an
alarm control panel, door strike, camera, high current relay or some other devices. Transmitters are used to activate or control the devices.
The receiver should be mounted indoors or inside a weather resistant non-metallic housing for outdoor use.

RECEIVER
OPERATING PARAMETERS
|
Status
Supervision: |
Monitored on each channel for hourly status transmissions, reports status
exception if no transmissions received within last 8-hour time period; one
common status output provided for all channels; 7-segment display indicates
channel where violation occurred; exception set and cleared by channel |
|
Enable Options: |
Status supervision enabled per channel;status enabled by cutting proper
jumper per channel;factory default disabled; Note: with status supervision
monitoring, it is not recommended to have more than one transmitter learned
per channel |
Low Battery
Supervision: |
Monitors each transmitter for low battery alarm; reports if any learned
transmitter low battery signal received; one common low battery output for
all transmitters; 7-segment display indicates channel where low battery
occurred; low battery set and cleared by individual transmitters; transmitter
that sends low battery report must send a good battery signal to clear low
battery condition |
|
Program Mode: |
Enabled by program jumper; remove to enter program mode |
Transmitter
Learn: |
Momentary press and release desired channel learn button; activate transmitter
with five seconds to learn it into desired channel |
|
Memory Erase: |
Hold appropriate channel learn button for more than 10 seconds and release;
transmitters learned into that channel will be erased from receiver memory |
Memory
Interrogation: |
Hold appropriate channel learn button for more than five and less than 10
seconds; alarm LED will flash the number of transmitters learned into selected
channels |
