DSC LC-103-PIMSK, LC-123-PIMSK - Dual-Tech Motion Sensor Manual

OVERVIEW

Fig. 1 Knockout holes

LC-L1ST accessory bracket Installation - Wall mount bracket (ceiling mount available)

The detector provides an analysis of environmental conditions through the entire movement speed frequency spectrum, allowing focus on intruders and eliminating environmental factors of false alarms. The spectrum analysis is embedded in the VLSI based electronics of the detector assuring high reliability and trouble free operation. Unique function-anti-mask-guarantees detector protection from non desirable approach and any kind of masking beginning from the distance 0.8m and closer.

As the LC-103-PIMSK / LC-123-PIMSK is a combined technology (PIR & microwave) an alarm signal relay activation occurs only when signals from both sensors (PIR & MW) are present at the same time. The effective detection range is the range of which the patterns (PIR & MW) are intersected. The GAIN potentiometer adjustment changes the MW signal intensity so that the effective pattern will be scaled. This Installation Manual shall be used in conjunction with the Installation Manual of the Control Panel.

TYPICAL INSTALLATION

Select mounting location
Choose a location most likely to intercept an intruder. (Our recommendation is a corner installation). See detection pattern (Fig.3). The quad-element high quality sensor detects motion crossing the beam; it is slightly less sensitive detecting motion toward the detector.

Fig. 3 Lens Pattern

Avoid The Following Locations:

• Facing direct sunlight.
• Facing areas that may change temperature rapidly.
• Areas where there are air ducts or substantial airflows. The LC-103-PIMSK / LC-123-PIMSK perform better when provided with a constant and stable environment.

This detector shall be installed and used within an environment that provides the pollution degree max 2 and overvoltages category II, NON HAZARDOUS LOCATIONS, indoor only. The detector is designed to be installed by service persons only.

NOTE: The anti-mask detection output will open for a minimum of 30 seconds and will close only if a signal is received from the PIR after the initial 30 second period.

MOUNTING THE DETECTOR

Fig. 2 Detector Installation

1. Remove the front cover by unscrewing the holding screw (Fig. 2-11) and gently raise the front cover. (Fig. 2-5)
2. Remove the PC board by unscrewing the holding screw located on the board.(Fig. 2-9)
3. Break out the desired holes for proper installation (Fig. 1–2) for flat mount or Fig. 1-3 for corner mount) Use 4 screws type 3x30mm.
4. The circular and rectangular indentations at the bottom base (Fig. 1-1, Fig. 1-4) are the knockout holes for wire entry.
5. Mount the detector base to the wall or corner.
6. For optional LC-L1ST accessory bracket installation open hole Fig. 1-6 for the bracket screw and install Bracket wall adapter (Fig. 2-1&3) or Bracket ceiling adapter (Fig. 2-2&3)
7. Reinstall the PC board by fully tightening the holding screw.
8. Connect wire to terminal block.(Fig. 4)
9. Replace the cover by inserting it back in the appropriate closing pins and screw in the holding screw.

If back tamper is assembled (Fig.1-6) there is no bracket option and the detector must be installed in flat mounting only

DETECTOR INSTALLATION

Terminal Block Connections (See Fig. 4)

Fig. 4 Terminal block

Terminals 1 & 2 - Marked "T1, T2" (TAMPER) Connect these terminals to a 24-hour normally closed protective zone in the control unit. If the front cover of the detector is opened, an immediate alarm signal will be sent to the control unit.

Terminals 3 & 4 - Marked "AM: NC, C" This is the alarm output relay of AntiMask detection.

Terminal 5 Marked "NC" - This is the NC (Normally Closed) output of ALARM relay. (This contact is functional on LC-103-PIMSK and LC-123-PIMSK)

Terminal 6 Marked "C" - This is the COMMON output of ALARM relay.

Terminal 7 Marked "NO" - This is the NO (Normally Open) of ALARM relay (This contact is functional on LC-123-PIMSK only).

Terminal 8 - Marked " - " (GND) Connect to the negative Voltage output or ground of the control panel.

Terminal 9 - Marked " + " (+12V) Connect to a positive Voltage output of 9.6-16VDC source. Use only a listed power limited source.

Note: The detector shall be provided with minimum of 4 hours of standby power from either a listed compatible control unit or power supply.

SETTING - UP THE DETECTOR

(Dipswitch Fig.5-2)

LED ENABLE / DISABLE

Switch 1. Used for Setting "LED"

Position Up "ON" - LED ENABLE The RED LED will activate when the detector is in alarm condition. (Factory Settings)

Position Down "OFF" - LED DISABLE The LED's are disabled.

NOTE: The state of the switch "LED" - does not affect the operation of the relay. When an intrusion is detected, the alarm relay will switch into alarm condition for 2 sec. In AM alarm condition all 3 LED's blink together regardless of the LED switch position.

ANTI MASK FUNCTION

Switch 2. Used for Setting "AM" - Anti Mask function

Position Up "ON" - protection against masking the detector from 0.4m and closer. (Factory Settings)

Position Down "OFF" - protection against masking the detector from 0.8m and closer.

PIR SENSITIVITY ADJUSTMENT

Switch 3. Used for Setting "PIR" - provides sensitivity control of PIR according to the environment.

Position Up "ON" - (Pulse=1) - High sensitivity for stable environments. (Factory Setting)

Position Down "OFF" Position - (Pulse=Auto) - Low sensitivity for harsh environments. For ULC Installations use this position

PET IMMUNITY SETTING

Switch 4. Used for Settings "PET" 15kg-25kg(33lbs-55lbs)

Position Up "ON" - Immunity to an animal up to 15 kg (33lbs)

Position Down "OFF" - Immunity to an animal up to 25 kg (55lbs) (Factory Settings)

Note: Pet immunity feature has not been tested by UL.

NOTE: Detector must be restart by temporary remove power before the new settings will take effect.

RANGE CALIBRATION

(Fig. 5.1 and 5.4)

The "MW" potentiometer adjusts the detection Range of MW between Minimum and Maximum (factory set to Middle Position).

The "PIR" potentiometer adjusts the detection Range between Minimum and Maximum (factory set to Middle Position).

Fig. 5 PCB Layout
Note: The "MW" and "PIR" pots may need to be adjusted to the Maximum positions in order to achieve maximum area of coverage as indicated in Fig. 3.

NOTE: The "MW" and "PIR" potentiometer may need to be adjusted to the Maximum positions in order to achieve maximum area of coverage as indicated in Fig. 3.

Coverage area: 50 ft x 50 ft (minimum sensitivity) and 60 ft x 50 ft (maximum sensitivity
For ULC Installations use sensitivity settings between MIN and MID positions and PIR pulse count set to AUTO. (DIP 3 is OFF)

WIRE SIZE REQUIREMENTS

Use #22 AWG (0.5 mm) or wires with a larger diameter. Use the following table to determine required wire gauge (diameter) and length of wire between the detector and the control panel.

WALK TESTING

Upon installation, the unit should be thoroughly tested to verify proper operation. The end user should be instructed on how to perform a walk test weekly.

Make sure detector has been set up: Pulse=1, LED=ON and protected area cleared of all people. Create motion in the entire area where coverage is desired, observe the Green LED for PIR detection, and Yellow LED for MW detection. Should the coverage be incomplete, readjust Range or relocate the detector.

Once coverage is as required, the alarm LED may be disabled.

Use the optional LC-L1ST wall mount / ceiling mount brackets to solve placement problems.

The brackets allow for horizontal positioning of the detector.

Note: For UL installations the detector shall be tested annually.
