For best results when installing a sensor/transmitter to monitor vehicle activity, mount the sensor at 30 to 34 inches above the ground and angle it toward an oncoming car's radiator. Since the sensor uses infrared technology to detect activity, aiming the sensor to the hottest part of the car will insure maximum results.

Now Voice Alert can let users know when a door, window or gate opens or closes by using the sensor/transmitter as a wireless transmitter.

Move the PIR enable/disable switch to the OFF position and hardwire a trigger device into the contact closure on the sensor/transmitter. When the device is activated it will cause the transmitter to send a wireless signal to Voice Alert's Receiver/Speaker. Voice Alert's Receiver/Speaker will then play the recorded message designated for that zone.

Experts agree that people have about four minutes or less to escape a home after a fire alarm sounds.

Use the contact closure on a Voice Alert sensor/transmitter to tie into the smoke alarm's output. When the fire system triggers an alarm, the system issues an audio command that fire has been detected.

Hearing a voice message can help reduce confusion.

The Voice Alert Sensor/Transmitters are designed to work well outside regardless of the weather. The sensor's weatherproof housing offers protection from rain, wind and snow. When installed outside the Sensor/Transmitters do best when in a covered area and not facing directly into the sun. In very cold climates a lithium battery will provide better performance and longer use.

When placing a Voice Alert sensor in the mailbox to alert homeowners when the mail carrier has delivered the mail, consider placing the sensor on the mailbox flap. Placing the sensor at the back of a metal mailbox may restrict the wireless signal and the base unit will not be alerted. If the sensor is on the mailbox flap it can transmit through the air when the flap is opened by the mail carrier.

For customers looking for a way to broadcast their Voice Alert messages into additional rooms, combining Voice Alert with RadioShack's 4-channel 900MHz Wireless Intercom just might be the solution.

Simply connect the two systems together using Voice Alert's LINE OUT and RadioShack's auxiliary input. Then, when a Voice Alert sensor is triggered, the message will broadcast to any room with one of the wireless intercom speakers. Because both systems are wireless, it's a snap to install.

Of course another easy solution is to program additional Voice Alert Receiver / Speakers for each room you want to sound the messages. This is a particularly good option if your customer needs more than one Sensor / Transmitter so you can provide additional full systems.

When severe electrical storms strike during the summer, Voice Alert users occasionally may notice that their sensors don't respond immediately following the storm. The positive and negative charges floating through the air during the storm sometimes scramble the wireless signal from the sensor to the base unit. Re-programming the system will get both devices back in sync and only takes a few seconds to do. Here's how:

• Slide the switch on the front of the base unit from "Run" to "Program."
• Wave your hand in front of the Sensor, this will trigger the Sensor.
• The Setup LED on the top of the base unit will come on.
• Press the appropriate message button (1 - 6) on the front of the base unit associated with this Sensor. This registers (i.e. synchronizes) that particular Sensor to the chosen zone.
• Slide the switch back to the "Run" position.
