INSTALLATION HINTS

Avoid direct sunlight.
Avoid mounting detector where movement of Fans or Air Conditioning Fans can be detected.
Avoid vapor or high humidity that can cause condensation.
Avoid Curtain, Screen, etc. blocking detection area.
Do not install outdoors.

Never repair or modify product. It may cause accident, fire hazard or electric shock.

When damage has occured to the product, i.e. water logged, abnormal things inside product, overheating or smoking, strange smells etc., immediately stop using product and contact your supplier. Otherwise, continued use in such condition may cause electric shock or fire hazard.

Mount securely. A falling product may cause injury.

DETECTION AREA

**ATTENTION**
The specified detection area can be achieved by mounting the unit at a height of 8ft.(2.4m). Mounting at a lower or higher height may reduce the area of coverage.

DESCRIPTION AND OPERATION

INSTALLATION

Loosen fastening screw and remove cover.
Lead in wires through knockouts along the wiring guide on the rear side of base. Mount base with supplied screws. When using a bracket, check matching knockout position before opening mounting holes. Wire accordingly.

When you remove the PCB, push down on the hook under PCB and remove it from its base. Attachment of PCB is the reverse of removal.
Remove the screw fixed the lens holder(CX-702V Only), open the cover's hook and then lens cover can be removed.
Remove lens holder carefully. Select wide angle or long range according to Section 6-2. (Note: Factory default is WIDE ANGLE.)
Check to confirm that the lens is in the desires position. Press down the lens holder until it clicks into place along the guide of cover. Fix the screw at the end.
Conduct a walktest and make adjustments. Fit cover using fastening screw.

WIRING

Power wires should not exceed the following lengths.

	CX-702		CX-702V
WIRE SIZE	12V	14V	12V	14V
AWG 22 (0.33mm²)	1700ft. (520m)	3700ft. (1130m)	3700ft. (360m)	2520ft. (770m)
AWG 20 (0.52mm²)	2690ft. (820m)	5830ft. (1780m)	1830ft. (560m)	4000ft (1220m)
AWG 18 (0.83mm²)	4290ft. (1310m).	9350ft (2850m)	2950ft. (900m)	6430ft. (1960m)

When using two or more units on one wire, the maximum length is obtained by dividing the maximum wire length listed above by the number of units used.

* UL requires CX-702 to be connected to a UL listed power supply capable of providing a nominal input of 12VDC 11mA(max.) and battery standby time of 4 hours.
* For UL Listed systems, do not connect field wiring more than 25ft. to Alarm Memory, and DL terminals.
* The equipment shall be installed in accordance with the National Electrical Code, NFPA 70.

ADJUSTMENTS FOR REQUIRED AREA PATTERN

The CX-702 is designed to provide ideal detection areas for different patterns ranging from 40ft.(12m) to 70ft.(21m) Wide Angle, and 80ft.(24m) to 150ft.(45m) Long Range. The following adjustments will provide ideal detection areas for each of these requirements.

DETERMINE THE AREA PATTERN
Before making adjustments, determine the pattern area, detection range mounting height.
SELECTING WIDE ANGLE OR LONG RANGE DETECTION
1. Inverting the lens will select either the Wide Angle or Long Range detection patterns.
2. Please note markings "W(Wide Angle)" and "L(Long Range)", on each side of lens.
3. For Wide Angle, "W" will be on top of lens.
4. For Long Range, "L" will be on top of lens.
VERTICAL ADJUSTMENT OF DETECTION AREA
Adjust the vertical angle accrding to the desired detection range and mounting height.

Set the upper edge of the lens at either the "A", "B" or "C" position.
The following chart illustrates the different position setting.
Confirm the detection area by conducting a walktest.

FUNCTIONS

Always conduct a walktest after changing the position of this switch to ensure the detector is still providing optimum coverage.

LED ON / OFF
Jumper Pin Switch The Alarm LED indicator can be switched either "ON" or "OFF".
D.L. terminal (CX-702V Only) LED can be enabled or disabled remotely from control panel by D.L. terminal.
1. Place Jumper Pin Switch in OFF position.
2. LED"ON": Connect DL terminal to common ground with detector.(0~1VDC, grounded) LED"OFF": No Connection to the DL terminal.(OPEN or +5~16VDC)

PULSE COUNT
The Detection Mode can be switched to either "2" or "4" mode depending on the environmental conditions of the installation.
2: For normal applications.

4: For use in hostile areas where there may be movement of small animals or other objects such as fax machines or curtains.

When the "4" is selected, the detector's sensitivity may seem sluggish. It is therefore important to always conduct a walktest to ensure that the desired coverage is given.

Do not use pulse count 4 for Long Range detection.

ALARM MEMORY ( CX-702V Only )
Alarm Memory
This function is used to indicate if the detector was activated while the panel was armed. It will cause the red LED on the Detector to illuminate once the panel has been disarmed. Compatible Control Panel is required for Alarm memory.
Connect A.M. terminal to Control Panel's Control Voltage Signal terminal (System Arming Status Voltage Output).

CONTROL VOLTAGE SIGNAL

	POSITIVE	NEGATIVE
System Armed	OPEN or +5~16VDC	0~1VDC(grounded)
System Disarmed	0~1VDC(grounded)	OPEN or +5~16VDC

Operation
If the unit triggered during armed period, when the system is disarmed, LED will remain lit to confirm that it reported an alarm.

Alarm Memory will operate even when LED is switched OFF.
Alarm Memory will not operate while system is disarmed.
After Alarm Memory latches, Alarm Output and LED operate normaly during armed period.

Reset
Alarm Memory resets automatically when system is re-armed.

POSITIVE : Leave AM Jumper as it is.
NEGATIVE : Cut AM Jumper as shown.

TROUBLE SHOOTING

PROBLEM	PROBABLE CAUSE	REMEDY
LED does not light.	Improper power supply voltage (disconnection, low voltage).	Correct supply voltage to 9.5 - 16V DC.
	Improper detection area.
	LED switch is OFF.	Turn on the switch.
	Improper polarity to detector.	Switch positive and negative at terminal.
LED lights even though no person within area.	Moving object within area (curtain, wall hanging, etc.).	Remove the souces from the detection area.
LED lights even though no person within area.	Temperature of object within area changing rapidly (heater, air conditioning, etc.).	Remove object from the detection area.
LED lights but signal is not sent.	Relay contact is stuck or damaged due to overloading.	Check load of output. The unit needs repair or replacement.
LED continues to light	Faulty wiring.	Wire correctly.
	Poor connection of alarm memory.	Reconnect wire.
	Wrong control voltage from panel.	Must be 0-1V DC(grounded)
