MODEL 1582-725 RF Switch 1.0 General 1.1 Equipment Description - The 1582-725 RF Switch has two independent switches (A and B) in a single 1 3/4” chassis. Each switch provides Auto, Manual, or Remote relay switching between CH1 and CH2. Alarm conditions on CH1 and CH2 are detected if a contact closure (to ground or an open, selectable) occurs. Switching logic can be selected as follows: 1) CH1 Prime Mode - Switches from CH1 to CH2 only if CH1 alarms and CH2 is good.

2.4 PC Board Settings 2.4.1 On-Card Jumpers NOTE: Dot position means jumper goes from center pin to the pin nearest the dot on the PCB. Also the first jumper designation is for switch A (J1) and the second is for switch B (J101). JP1, JP101 - 3-pin jumper that works with JP3, JP103 In the dot position when channel 1 alarms the 1582-14 will switch to channel 2 until channel 2 alarms. At this point, if channel 1 is still in alarm, the switch will stay on channel 2.
JP10, JP110 - DO NOT ADJUST THESE! JP15, JP16, JP17, JP18 - DO NOT ADJUST THESE! JP25,JP125 - DO NOT ADJUST THESE! JP26,JP126 - DO NOT ADJUST THESE! 2.4.2 On-Card Switches S3, S103 - Initial Channel Select (ICS) Mode- 4-position DIP switch Selects the Initial Channel Select mode when JP1,2,3, JP101,102,103,in Dot and JP4, JP104 in Non-dot. S3, S103 positions 1,2,3,4 to ON - ICS is enabled.

2.6 Switch Mode Setup - The following gives the switch mode settings of the on board controls that can be changed in the field: SWITCH A JP1, JP2, JP3, JP4; S3; SWITCH B - JP101, JP102, JP103, JP104, S103 (Section 2.3, 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.
