Project the alarm outside! The Remote Siren & Strobe allows you to place the warning right where you want it. Direct police anywhere on your site to shorten response time. This accessory is triggered when the tattletale's siren and strobe go off. Constructed of strong rust-free die cast aluminum and is gasketed to provide weather resistance. Must be plugged into A/C power.
When a base station and accessories are bought individually they are not programmed to work with each other.
You need to purchase the programmer: 7T-PROGRAMME - http://www.internet-security-inc.com/catalog/product_info.php?products_id=941499
The programmer connects to the transmitters in the sensors, or other accessory – comes with instructions
Then, you must call tattletale with the serial number on the base unit to obtain the “house code” for that unit…
You then need to enter the house code into the programmer to program the accessory to match the base unit.
