Manual for the Heath/Zenith DualBrite® Motion Sensor Light Control, Models SL-5312 and SL-5318.
Manual for the Heath/Zenith DualBrite® Motion Sensor Light Control, Models SL-5312 and SL-5318 — a motion-activated dusk-to-dawn floodlight control with adjustable range, ON-TIME, and DualBrite® half-bright timer.
Model 5318 meets ENERGY STAR® guidelines when the DualBrite® function is off, ON-TIME is set to 1 or 5 minutes, and bulbs used are 120W max.
| Mode | On-Time | Works |
|---|---|---|
| Test | 5 Seconds | Day & Night |
| Auto | 1, 5, or 20 Min | Night |
| Manual | To Dawn* | Night |
| Accent | 3, 6 Hr., to Dawn | Night |
* Manual mode resets to Auto Mode at dawn. Note: after first power-on, wait about 1½ minutes for the circuitry to calibrate.
Put the ON-TIME switch on the sensor bottom to TEST and the DualBrite® switch OFF.
Put the ON-TIME switch in the 1, 5, or 20 minute position.
Manual mode only works at night, since daylight returns the sensor to AUTO. Flip the light switch off for one second, then back on, to toggle between AUTO and MANUAL MODE. Manual mode only works with the ON-TIME switch in the 1, 5, or 20 minute position.
Mode Switching Summary — TEST: move ON-TIME switch to 1, 5, or 20 minutes. AUTO: default. MANUAL MODE: flip light switch off for one second, then back on. If you get confused, turn power off for one minute, then back on — after the calibration period the control returns to AUTO mode.
The light comes on at half bright for a selected time after dusk (Off, 3 hr., 6 hr., or until dawn). Selecting OFF disables this feature — normal motion-sensing continues to work as described. If motion is sensed, the light turns on full bright for the ON-TIME period (1, 5, or 20 minutes), then returns to dim mode.
For easy installation, select an existing light location with a wall switch for replacement. For best performance, mount the fixture about 8 ft. (2.4 m) above the ground — if mounted higher, aiming the sensor down will reduce coverage distance.
For under-eave installation, the sensor head must be rotated for proper operation and to avoid risk of electrical shock: swing the sensor head toward the clamp screw joint, then rotate it clockwise 180° so the controls face down. If the sensor pops out of the ball joint, loosen the clamp screw, push the sensor back into the ball joint, and re-tighten.
To avoid water damage and electrical shock, keep bulb holders 30° below horizontal. Keep bulbs at least 1" (25mm) from the sensor and do not let them block the lens.
Avoid aiming the sensor at objects that change temperature rapidly (heating vents, A/C), areas with heavy pet/vehicle traffic, or large light-colored reflective objects — these can cause false triggering. Do not point other lights at the sensor.
Warning — Risk of fire: Do not aim the bulbs at a combustible surface within 3 ft. (1 m).
| Spec | Value |
|---|---|
| Range | Up to 70 ft. (21m); 100 ft. (30.5m) with Range Boost (varies with temperature) |
| Sensing Angle | Up to 240° |
| Electrical Load | Up to 300W Max. Tungsten (up to 150W max. each bulb holder) |
| Power Requirements | 120VAC, 60Hz |
| Operating Modes | TEST, AUTO, MANUAL MODE |
| Time Delay | 1, 5, 20 minutes |
| DualBrite® Timer | 3, 6 hours, Dusk-to-Dawn |
| Symptom | Possible Cause | Solution |
|---|---|---|
| Lights will not come on | Switch off; bulb loose/burned out; blown fuse; daylight turn-off in effect; wiring error; control aimed wrong | Turn switch on, replace bulb, replace fuse/reset breaker, recheck after dark, verify wiring, re-aim control |
| Lights come on in daylight | Installed in a dark location, or in TEST mode | Normal in dark locations; set switch to 1, 5, or 20 minutes |
| Lights come on for no apparent reason | Sensing small animals/traffic; range set too high; DualBrite® timer active | Re-aim control; reduce range; normal operation with DualBrite® |
| Lights turn off too late in Dusk-to-Dawn setting | Installed in a dark location | Relocate control, or use 3 hr./6 hr. setting |
| Lights stay on continuously | Flood lamp too close/pointed at heat source; heat source in range; manual mode | Reposition lamp/objects; reduce range; switch to AUTO |
| Lights flash on and off | Heat/light feedback from flood lamps; reflected heat; TEST mode warming up; light leaking through reflectors | Reposition lamp/control; normal during warm-up; replace with quality PAR38 lamps with metal protectors |
| Lights flash once, then stay off in manual mode | Control is detecting its own lights | Reposition flood lamps to keep area below the control relatively dark |
