recording devices, AC power in, DC power in, remote reset as well as relay logic and power terminations for the multiple alarm relay circuit. Form C relay outputs may be discreet, zoned or common by gold plated jumper tabs located on the controller mother board. Form C dry contacts; common, normally open and normally closed, are provided for 3 alarms; High, Low and Fault. Contacts are rated at .6 amp @125 VAC / 2 amp @ 30 VDC.
1.2 MULTIPLE ALARM RELAY CIRCUIT A multiple alarm relay circuit (figure 2) mounted on the controller mother board is provided with each Detcon Model 610A-FB. The alarm circuit consists of 4 interposing relays (contacts are rated 8 amp @ 117 VAC / 5 amp @ 30 VDC) with 24VDC coils as standard. Other coil voltage ratings must be specified at time of order. The alarm circuit can be configured to output Form C dry contacts (common, normally open and normally closed), AC power or DC power.

1.4 REMOTE RESET A remote mounted normally open momentary switch may be used to reset all Model 10A controllers. The reset function is effective when the Model 10A's respective alarms have been programmed in the latching position and alarm conditions have passed. Each Model 10A controller has its own alarm reset switch which is discussed further in section 2.0. 1.5 INSTALLATION Step 1. Securely mount the 610A-FB enclosure (see figure 4). Figure 4 - Dimensions/Mounting Detail .31" DIA. MOUNTING HOLE .
Step 5. Refer to installation and wiring detail of remote mount sensor assemblies as detailed in section 3.0. Terminate field wiring from sensors to Model 610A-FB lugless terminal strips located on the controller mother board as shown in figure 1. Note: Based on the application and use of relay contact outputs, complete all wiring terminations prior to application of power. Shut-in controls may be omitted until system test is complete. 1.
