·····•
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.
As the ALH-PIRMW is a combined technology (PIR & microwave)
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 ALARM 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.
Avoid The Following Locations:• Facing direct sunlight.• Facing areas
that may change temperature rapidly. • Areas where there are air ducts
or substantial airflows.
The ALH-PIRMW performs 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.
MOUNTING THE DETECTOR
1. Remove the front cover by unscrewing the holding screw (Fig. 2-11)
and gently raise the front cover. (Fig. 2 ·S)
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
fiat 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.
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 nat mounting only.
DETECTOR INSTALLATION
Terminal Block Connections (See Fig. 4)
Terminal 1- Marked"." (GND) Connect to the negative Voltage output
or ground of the control panel.
Terminal 2 •Marked"+" ( +12V) Connect to a positive Voltage output of
9.6·16VDC source. Use only a listed power limited source.
Terminals 3 & 4 • Marked 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.
Terminal 6 & 7 Marked RELAY· These terminals are the NC (Normally
Closed) output and COMMON output of ALARM relay.
SETTING· UP THE DETECTOR (Dipswitch Fig.5-2)
LED ENABLE/ DISABLE
Switch 1 ofdipswitch marked "LED" -LED's Enable/Disable
Position Up "ON" -LED's ENABLE The 3 LED's will be activating Red for
ALARM, Green for PIR detection, Yellow for MW detection.
Position Down "OFF" -LED's DISABLE The LED's are disabled.
NOTE: The state of the switch "LED" - does not affect the operation of
the relays. When an intrusion is detected, the alarm relays will switch
into alarm condition for 2
sec.
PIR SENSITIVITY ADJUSTMENT
Switch 2 of dipswitch marked "PIR" · provides sensitivity control of
PIR according to the environment.
Position Up"ON" · (Pulse=l)-High sensitivity for stable environments.
Position Down"OFF"-(Pulse=Auto)•Low sensitivity for harsh
environments.
MW SENSITIVITY ADJUSTMENT
Switch 3 of dipswitch marked "MW" -provides sensitivity control of
Microwave detection according to the environment.
Note: Brackets not included or supplied.

Coverage area: 50 ft x 50 ft (minimum sensitivity)
and 60 ft x 50 ft ( maximum sensitivity)

PET IMMUNITY SETTING
Switch 4 of dipswitch marked "PET" -provides setting for pet weight
15kg (33lbs) or25kg (55lbs)
Position Up "ON"• Immunity to an animals up to 15 kg (331bs)
Position Down "OFF"• Immunity to an animals up to 25kg (55lbs)
AND/OR FUNCTION SETTING
Switch 5 of dipswitch marked "A/0" • provides setting for ALARM
relay activation.
Position Up "ON" • OR mode • the ALARM relays will activate as a
function of PIR OR MW detection ( The first channel that detects will
activate the ALARM)
Position Down "AND"· AND mode· the ALARM relays will activate as a
function of both PIR AND MW detection.
NOTE: Detector must be restart by temporary remove power before the
new settings will take effect.
RANGE CALIBRATION
The "MW" potentiometer (Fig. 5-4) adjusts the MW detection range
between minimum and maximum (factory set to middle position).
The "PIR" potentiometer (Fig. 5-1) adjusts the PIR detection range
between Minimum and Maximum (factory set to Middle
Position).between Minimum and Maximum (factory set to Middle
Position).
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.
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
IMPORTANT NOTE: 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=l, 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 BK-04 wall mount or ceiling mount brackets to solve
placement problems. The brackets allow for horizontal positioning of
the detector.
