Frequently Asked Questions - LC151 DSC

What is the detection range of the DSC LC151 detector?

The detection range is 15 meters maximum (15 to 49 ft) when the detector is installed at a height of 2.4 m. It can be adjusted between 5 and 15 m using the LC-B1-15X outdoor mounting bracket.

How to adjust the sensitivity of the LC151?

Sensitivity is adjusted via a potentiometer (position '-' to '+') and a microwave intensity jumper (H for high, L for low). Adjust according to the environment: low risk: potentiometer at position 5, jumper H; high risk: position 4-5, jumper L; very noisy area: position 1, jumper L.

Is the LC151 weather resistant?

Yes, it is designed for outdoor use with a sealed plastic weatherproof housing. It withstands direct sunlight, wind up to 30 m/s, snow, and rain.

Can it ignore pets?

Yes, without a special lens, it ignores pets up to 15 kg (33 lb). With the LC-F1-15X filter, immunity increases to 36 kg (80 lb).

How to test the proper functioning of the detector?

After installation, wait for the 30-second warm-up period. Set the LEDs to ON. Walk perpendicular to the detection zone: the green, yellow, and red LEDs should light up simultaneously in case of alarm. Allow 5 seconds between each test. An annual test by the installer and a weekly test by the user are recommended.

What cables to use for connection?

Use a wire gauge of AWG 22 (0.5 mm²) or larger. The maximum length depends on the gauge: for example, 205 m for AWG 22, up to 3400 ft for AWG 16.

What to do in case of false alarms?

First check the location and environmental conditions. Adjust the PIR sensitivity via the potentiometer and reduce the microwave intensity (jumper to L). Eliminate sources of heat, reflective surfaces, or obstacles in the detection zone. Consult the adjustment table in the manual according to the noise level.

Does the detector have tamper protection?

Yes, two tamper switches: one opens if the top cover is removed, the other if the detector is detached from the wall. The TAMPER terminals (3 & 4) connect to a 24-hour zone of the control panel.

What installation height do you recommend?

The recommended height is 2.1 m, with an allowable range of 1.8 to 2.4 m. Mounting on a solid, level wall is essential for optimal detection.

How to power the LC151?

The required power supply is 9.6 to 16 VDC. Connect terminal 1 (+) to positive voltage and terminal 2 (-) to ground. Use an approved limited power source. The detector must receive at least 4 hours of standby power before use.

4 Detection Pattern

The LC-151 has a 90° top view PIR and MW detection pattern with over 15m (49 ft) detection distance (when installed at 2.4m (7.8 ft) above the ground surface).

EN

Standard Lens

TOP VIEW

SIDE VIEW

The LC-151 can differentiate between pets and human bodies and alert accordingly by utilizing microwave movement detection combined with a PIR detection beam.

An intrusion is defined by the PIR detection beam being crossed and a microwave detection occurring, causing an alarm.

No alarm will be generated if only the PIR detection beam is crossed or if only a microwave detection occurs.

5 Selecting mounting location

The installation of the LC-151 requires a solid, level base for the mounting bracket and must be located in a manner that when the detector is mounted, it is facing the center of the

desired detection zone.

It is recommended that the detector will face a solid border limiting the detection area, such as the building structure or fencing wall, to avoid undesired detection range.

The protected area must be free from obstacles like walls, fences, trees, ditches and other microwave detectors.

EN

Choose a location most likely to intercept an intruder according to detection pattern on page 5.

Avoid the following Installation Locations:

• Facing direct sunlight.
• Facing areas subject to rapid temperature changes.
• Mounted at more than 10^ from the vertical or horizontal plane.
• Facing metal doors.
• Near direct sources of heat or airflow.
• Clear all physical obstacles from the detection area (e.g. plants, laundry, etc.)
• Clear all light reflecting surfaces from the detection area, including puddles or other standing water.

- Avoid installation on the following types of ground: Thick vegetation, Grass (un-mown), Water, Sand and Metal.

NOTES:

• Recommended installation height is 2.1m (6.8 ft).
• The PIR sensor detects motion crossing the beam; it is less sensitive detecting motion towards the detector.
• The LC-151 performs best when provided with a constant and stable environment.
• In order to ensure suitable operation of the LC-151, the type of ground should be one of the following: Asphalt concrete, Cement, Soil, Clay, Gravel or Grass (mown).
• Sensitivity adjustment may be required upon extreme temperature changes.

Extremely high temperature will reduce detection range. Extremely low temperature will increase detection range.

Choose proper installation location to avoid resetting.

6 Detector Installation

Important! Prior to installation, read both "Operation" and "Selecting the mounting location" sections carefully.

1. Install the detector in such manner that the intruder is most likely to cross the detection area from side to side.

1. The detector is to be installed at height of 1.8 to 2.4 meters (5.9 to 7.8 ft), ideally 2.1m (6.8 ft)

1. Make sure to attach the metal bracket to a leveled straight and firm wall, leaving 10cm (3.9 inches) from the top and 10cm (3.9 inches) from both sides, for easy installation and maintenance.

1. Placing the detector on perpendicular wall is required for guarding a side window opening. Alternately the LC-B1-15X Outdoor Mounting bracket can be installed on the same wall, allowing the detector beam to be rotated towards the window.

Terminal 1 - Marked “+” (+12V) - Connect to a positive Voltage of 9.6 -16Vdc source (usually from the control panel)

Terminal 2 - Marked “-” (GND) - Connect to the ground of the control panel.

Terminals 3 & 4 - Marked "TAMPER" - If a Tamper function is required connect these Terminals to a normally closed 24-Hour Tamper Zone on the control panel.

If the top cover of the detector is opened or the detector is detached from installation wall, an immediate alarm signal will be sent to the control panel.

Terminal 5 - Marked "EOL" - End of line – optional terminal for end of line resistors connections.

Terminals 6, 7 & 8 - Marked “NC / C / NO” - These are the output relay contacts of the detector. Connect to a zone input on the control panel. When an intruder is detected, alarm relays (N.C. and N.O.) will switch for 1.8 sec.

7.1 Wire Size Requirements

Use #22 AWG or larger wires. Use the following table to determine required wire gauge and length.

Wire Length [m]	205	310	510	870
Wire Length [ft.]	800	1200	2000	3400
Wire Gauge [#]	22	20	18	16

8 Settings & Adjustments

8.1 Detection beam direction

The LC-151 detection beam direction is fixed. As a result, it is recommended to face the intrusion area with the detector.

8.2 Detection beam range setting

The detection range may be set by tilting the detector while installed using the LC-B1-15X Outdoor Mounting Bracket. The range may vary between 5 and 15m (16ft to 49ft).

8.3 Sensitivity Adjustment

The calibration of detector sensitivity is performed by a single sensitivity potentiometer and a Microwave intensity jumper. Changing the PIR sensitivity and microwave intensity affects immunity to environmental noises and allows the detector to operate without nuisance alarms in noisier environments. The microwave intensity jumper is marked with "H" (high) and "L" (low) settings. The sensitivity potentiometer is marked with "-" to "+". Position "-" is the minimum sensitivity and position "+" is the maximum sensitivity. The PIR sensitivity and microwave intensity must be adjusted according to environmental conditions as follows:

• Low risk: very stable environment without interference from parking garages, parking space, playgrounds, football fields, service roads, etc.
• Risk: Stable environment with some trees, bushes, flowerpots, planters, etc.
• High risk: Unstable environment with different types of vegetation and grass and puddles.
• Very high risk: Unstable environment with winds and small pets, rats, mice, birds.
• Noisy area: Unstable environment with vegetation and water sources like swimming pool, lake, canal, weeds as well as small pets like cats and rabbits.
• Extremely Noisy are very unstable environment subjected to wind, snow, rain, with vegetation, water and large pets like dogs.

For Example:

If the detector is used in a space which contains several bushes and a swimming pool the environmental conditions should be considered a "Noisy Area"

8.4 Indications setting

The LC-151 has 3 LEDs that each points at different indication:

1. Green LED indicates PIR detection.
2. Yellow LED indicates Microwave detection.
3. Red LED – Indicates an alarm (logic AND of both Mircowave and PIR).

When the LED jumper is in the "ON" position the LEDs will be active. When the LED jumper is in the "OFF" position, the LEDs will not activate.

• If the LEDs are enabled, they will sequentially flash from left to right for the duration of the 30 seconds warm up period.
• Once the warm up period is complete, the detector is ready for use.

10 Test procedure

Walk Test

IMPORTANT NOTE: Once installed, the unit should be thoroughly tested to verify proper operation and coverage. After installation, the unit should be tested annually by the installer. The end user should be instructed on how to perform a weekly walk test.

Make sure LEDs control is set to "ON"

Ensure the detector has completed the 30 second warm up period before walk testing.

Make sure that the protected area is cleared of all people.

Create motion in the entire area where coverage is desired by walking perpendicular to the detection pattern.

Look at the LEDs whenever motion is detected - all LEDs are turned ON.

Allow 5 sec. between each test for the detector to stabilize.

Walk across the entire area where coverage is desired. Should the coverage be incomplete, readjust sensitivity or relocate the detector.

Once coverage is as desired the LEDs should be disabled.
