Section 5 – Gateways5-11Notes for Figures 5-3a and 5-3b:1. Letter “G” on printed wiringboard indicates pin 1 header.2. Receptacle position on header isdetermined by whether or notsensor is system-powered.3. Electrical position of tamper,where used.4. For break-only contact, jumperPID header pins 3 and 5, low-side feed and low-side return,respectively.5. Where no tamper is used,connect yellow wire to sameterminal with black wire.6. 494468 branch cable must beused in ceilings that are air-handling plenums.7. Do not connect more than eight4-wire smoke detectors to asingle PID. Install supervisoryrelay and EOLR in same outletbox used for electrically lastsmoke detector. All smokedetectors on the one PID mustbe located in the same firepoint.8. Transfer contact ofindependently powered sensoris shown. Sensor is powered byseparate power supply (notshown).9. Separately ordered EOLR,except for 7187 type sensor,which has own resistor.10. Use 370320 Junction Box whererequired.11. Make butt splices (X) of wireswith 810955 Scotchlok typewire connectors.LOW SIDE FEEDHIGH SIDE FEEDLOW SIDE RETURNHIGH SIDE RETURNBLKREDYELBLUFIXED PROTECTION(SCREENS - FLOORMATS OR FOIL)1234561234EOLRESISTOR(NOTE 2)(NOTE 1)HEADER RECEPTACLEPID CABLECONNECTOR BASIC BA - FIXED ANDMOVABLE SENSORSORORBLKREDYELBLUMOVABLEPROTECTIONTA(NOTE 3)NONCBLKREDYELBLUMOVABLEPROTECTIONNC(NOTE 4)BA NORMALLY-CLOSED(BREAK-ONLY)CONTACTBLKREDYELBLU975306 RESISTOR3010 OHM, 1%, 1/2W123456NOT USED(NOTE 1)HEADER RECEPTACLEPID CABLECONNECTORBASIC FA1234+12VDC- 12VDC494466 OR 494468BRANCH CABLE(NOTE 5)4 3 2 1+POWERALARMCONTACTS4-WIRE SMOKEDETECTOR(NOTE 7)REDBLACKBROWN BROWN435243 POWERSUPERVISIONRELAYYELBLUWATER FLOW ORSUPERVISORY DEVICE(NOTE 5)BLKREDTA(NOTE 3)NOFigure 5-3a: Basic Sensor Connections to PIDBLKREDYELBLU123456NOT USED(NOTE 1)HEADER RECEPTACLEPID CABLECONNECTOR1234+12VDC- 12VDC(NOTE 2)XXXXXXCONTACT(NOTE 8) SYSTEM-POWEREDSENSORCONTACT(NOTE 8)CONTACT(NOTE 8)SYSTEM-POWEREDSENSOREOLR(NOTE 9)COMBINATION OF SYSTEM-POWERED ANDINDEPENDENTLY POWERED SENSORS ON SAME LOOPBLKREDYELBLUOR GRNHEADER RECEPTACLEPID CABLECONNECTOR1234123456EOLRESISTOR(NOTE 1)D6441-4B, 494466OR 494468 CABLE(NOTE 6)BLKREDYELGRNXX XXXXBLKREDYELBLUOR GRNBLKREDYELGRNXX XXXXBLKREDYELGRN370320 JUNCTION BOX(NOTE 10)370320 JUNCTION BOX(NOTE 10)DOOR CONTACTSDOOR CONTACTS DOOR CONTACTSD6441-4B CABLE223414 TERMINAL UNITWHERE REQUIRED(NOTE 11)BASIC BA MULTIPLESENSORS ON SINGLELOOP(NOTE 2)Figure 5-3b: Basic Sensor Connections to PID
