Linear dxsr-1508 receiver

• The 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 OUTPUTS
  DXSR-1508:	8-Channel alarm outputs, one common low battery output, and one common status output
  Type:	Open collector
  Mode:	Factory set to normally open; can be globally selected as normally closed by internal jumper
  Current Rating:	100 mA maximum per output point
  CHANNEL OUTPUT OPTIONS
  Momentary:	1-second minimum, momentary closure on alarm
  Toggle:	Alternate alarm action (toggle on, toggle off)
  Latch:	Requires manual reset at receiver, or operates as a follower with door/window transmitters; latches "on" with open (alarm) condition; latches "off" with closed (restore) condition
  DISPLAY OUTPUT
  Channel Display:	One 7-segment LED indicator; displays flashing center dash in power on an standby; displays channel ID during alarm condition along with alarm condition LED; automatically clears when alarm output restores; displays "P" and channel ID during programming mode
  RF Activity:	Indicated by decimal point on 7-segment display; indicates radio receiver activity; flashes with received data
  Alarm Condition:	Three LED indicators - alarm, low battery, and status; displays conditions with corresponding channel ID
  Operating Voltage:	10.2 to 14.4 VDC or 12 to 16 VAC
  OPERATING CURRENT
  Standby:	30 mA
  Alarm:	Up to 120 mA
  Operating Temperature:	32° to 140° F (0° to 60° C)
  Dimensions:	7.25 in L x 1 in W x 5 in H (185 x 25.4 x 127 mm)
  Space Required for Installation:	7.5 in L x 14.0 in H
  Antenna:	Two, 9-1/2 in wire whip antennae (supplied)
  Mounting Hardware:	Four #6 x 1 1/4 in wood screws (supplied)
  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
