Changing the Motion Detector Sensitivity

The motion detector features Fast and Slow detection

modes, which are set on jumper J1. Jumper J1 is set at the

factory for the Fast detection mode. In a normal operating

environment, this setting provides the best detection.

In certain environments where rapid air movement,

heaters and other variables present problems, use Slow

detection mode to stabilize the detection.

Jumper "J1" is located in the bottom right corner of the

circuit board. To change the setting from Fast to Slow,

move the jumper over one pin, as shown in the diagram.

High Traffic Shutdown Mode

To prolong battery life, the motion detector uses a feature called High Traffic

Shutdown. When motion is detected, the device will transmit to the receiver

and will then shut down for six minutes. If motion is detected again during the

first six minute shutdown time, the unit will reset the shutdown timer to three

minutes. Each time the detector is tripped during the shutdown time, the timer

will be reset to three minutes again. The detector will thus remain in the shut

down mode until it does not detect motion for an entire six minute period.

The High Traffic Shutdown Mode affects testing the motion detector in two ways:

• When performing the module placement test, you must tamper the unit.

To do this, remove the detector from the backplate and then replace it.

Once the detector is replaced on the backplate the panel will show and/

or sound the result of the placement test at the keypad.

• When performing a system test, the unit must be left idle for six minutes

before testing can be performed. Once six minutes has passed, create

motion in front of the detector to see if the device is both detecting motion

and transmitting to the receiver.

Motion Detector Transmission Delay

A motion detector transmission is always delayed by five seconds. This is

necessary to prevent false alarms caused by a motion sensor transmitting

before a delay zone has a chance to report. This five-second delay cannot

be altered or disabled.

Walk Test Mode

The motion detector has a walk test mode which will activate an LED for

testing purposes. During normal operation, the LED will not turn on.

To put the detector in walk test mode, create a tamper by removing the

detector from its backplate and then replacing it. Each time the detector

senses motion, it will turn on the red LED. Five seconds after motion is

detected, the detector will send a signal to the receiver, and the LED will

flash rapidly 5 times. The detector will be in walk test mode until it has sent

10 transmissions.

NOTE: The Walk Test Mode will override the High Traffic Shutdown Mode.
