MODEL 1582-71/72 RF Switch 1.0 General 1.1 Equipment Description The 1582-71 provides Auto, Manual or Remote relay switching between CH1 and CH2 RF signals. Alarm conditions on CH1 and CH2 are either a contact closure to ground or an open (selectable). The logic controls two separate RF switches, X and Y. The 1582-72 has two independent switches. Switching logic can be selected as follows: 1) CH1 Prime Mode - Switches from CH1 to the CH2 only if CH1 alarms and CH2 is good.

2.0 Installation 2.1 Mechanical The 1582-71/72 consists of one RF/Controller PCB and one smaller PCB containing the RF inputs and outputs. It is housed in a 1 RU (1.75 inch high) by 12 inch deep chassis. Redundant switching power supplies provide power for the assembly. The 1582-71/72 can be secured to a rack using the 4 holes on the front panel.

2.3.1 PC Board Settings NOTE: Dot position means jumper goes from pins 1-2; non-dot means jumper goes from pins 2-3 JP1 - 3-pin jumper - 3-pin jumper that works with JP3 In the dotted position when CH1 alarms the 1582-71 will switch to CH2 until CH2 alarms. At this point, if CH1 is still in alarm, the switch will stay on CH2. When the CH1 alarm clears if CH2 is still in alarm, the switch will switch to CH1.
remotely if both channel alarms are clear or both channels are in alarm. The initial channel can also be selected if both channel alarms are clear or both channels are in alarm. S4 positions 1,2,3,4 to OFF - ICS disabled (Minimum Auto switching, Return to Last State Mode) The 1582-71 goes to the last state (CH1 or CH2) it was in when in AUTO after manually or remotely switching and returning to AUTO. Auto switching occurs only if current channel alarms and the other channel is clear.
2.5 Switch Mode Setup The following gives the switch mode settings of the on board controls that can be changed in the field with JP1, JP2, JP3, JP4; S4. ( Figure 2.3). All shown with external alarm = ground. 1) CH1 Prime Mode - Switches from CH1 to the CH2 only if CH1 alarms and CH2 is good. Switches back to CH1 when it is no longer in alarm or when both CH1 and CH2 are in alarm Non-dot JP1, JP3, JP4; Dot - JP2; S4 - ALL TO OFF. 2) Latch to CH2 Mode - Switches from CH1 to CH2 if CH1 alarms and CH2 is good.
