SECO-LARM ENFORCER E-931-S50RRGQ 50ft Reflective Beam Sensor — Manual

Complete installation, wiring, and alignment manual for the SECO-LARM ENFORCER E-931-S50RRGQ 50ft Reflective Photoelectric Beam Sensor — a weatherproof gate/driveway/perimeter beam sensor with a Form C relay output.

Overview & Features

• Up to 50ft (15m) sensing range, reflective photoelectric beam sensor (single-unit sensor + reflector, not a transmitter/receiver pair)
• Weatherproof (IP55) with anti-condensation housing
• Operating voltage: 12-30V DC/AC 60Hz, 100mA (polarity does not matter for power input)
• Form C relay output: 0.5A @ 30VAC/VDC; N.C. tamper switch: 500mA @ 30VAC/VDC
• Beam status LED and 10ms response time
• Operating temperature: -13°F to 140°F (-25°C to 60°C)

Specifications

Parts List

• 1x Sensor, 1x Reflector, 1x Mounting bracket, 1x Sensor hood
• 4x Cover screws, 2x Mounting screws, 1x Reflector mounting screw
• 1x Rubber ring, 1x Cable connector, 1x Removable terminal block, 1x 10KΩ resistor, 1x Manual

Wiring

Polarity does not matter for the power input (12-30V DC/AC, 60Hz, 100mA). Terminal block provides Relay N.C./N.O./COM outputs and a Tamper N.C. output. Connect the N.C. tamper terminal to the tamper circuit of an alarm control panel.

Note: Depending on the monitoring system used by the gate motor, it may be necessary to use either the N.C. output or connect the included 10kΩ resistor to the N.O. or N.C. output — refer to the gate operator manual/manufacturer for the preferred monitoring method.

Mounting

1. Unscrew the four cover screws and remove the cover.
2. Loosen the captive screw and remove the sensor from the mounting plate.
3. Using the included mounting screws, mount the mounting plate to the wall.
4. Use the cable breakout and cable connector at the bottom or rear of the sensor to run the wires.
5. Hang the sensor back on the plate and use the captive screw to secure it in place.
6. Re-attach the cover, replace the four screws, and attach the hood to the top of the sensor.

Wiring for the Bottom Cable Breakout

1. Puncture the cable breakout located at the bottom of the sensor using a screwdriver or other object.
2. Insert the short end side of the cable connector into the cable breakout hole and use the nut to secure it, tightening with a wrench as needed.
3. Run the wires through the end cap and cable connector.
4. Screw the end cap into the external side of the cable connector to prevent water from entering the unit.

Alignment

1. Mount the sensor and reflector so that they face each other (horizontal adjustment ±90°, vertical adjustment ±5°).
2. Connect power to the sensor; the LED will light as indicated in the LED chart below.
3. Unscrew the four cover screws and remove the cover.
4. Slowly turn the lens assembly left and right to find correct horizontal alignment.
5. Loosen the vertical adjustment screw to adjust the vertical angle.
6. Place the hood on the sensor by sliding the hood's ridges into the slots on the sides of the sensor.
7. Re-attach the cover, replace the four screws, and attach the hood to the top of the sensor.

Sample Applications

Garage door monitoring, gate monitoring, vehicle detection, and assembly-line/production line beam interruption sensing.

Optional Accessory & Compatible Sensors

Reflector Hood (E-931ACC-HR1Q) provides extra protection for the reflector; compatible with the E-931-S50RRGQ, E-931-S35RRQ, and E-931-S33PRGQ reflective photoelectric beam sensor models. Other beam sensor types are also available (dual/quad beam, curtain and barrier beam).

Troubleshooting

Warranty

Warranted against defects in material and workmanship for one (1) year from the date of sale to the original consumer customer, limited to repair or replacement. Void if damage is caused by acts of God, misuse/abuse, neglect, unauthorized repair/alteration, or faulty installation.
