Manual

• GEN2 – Second generation classic sensors with standard operating range (100 ft). Requiring two (2) AAA batteries (not included), they are auto-addressable (up to 65,000+ possible IDs) and measure 3.25″ x 1.5″ x 0.5″. Foam mounting tape and screws are supplied. (GEN2 sensors do not store a permanent address and therefore must be initialized and re-registered whenever batteries are replaced.

• GEN3 – There are two available third generation sensors: mini and basic. Both feature a transmit range of 200 ft. The mini sensor operates on a single CR2032 lithium coin-cell (included). The basic sensor includes a CR123A cell. Each is pre-programmed with a unique, permanent address (over 16 million possible IDs). The mini sensor measures 2.2″H x 1″W x 0.25″D and includes foam mounting tape (no screws). The basic sensor measures 3-1/16”H x 1-9/16”W x 1-3/16”D and includes foam mounting tape and screws.

• Notes:

• • The two product generations are not cross-compatible as they operate on different radio frequencies. Therefore, a 2nd generation controller will not accept a 3rd generation sensor. Nor will a 3rd generation controller recognize a 2nd generation sensor.
  • G2-classic and G3-basic sensors provide wired contact screw terminals for optional external wired switch (N/C) or closed contact loop. Unless you plan to utilize this input, it must be disabled to avoid inadvertent trigger. To disable, simply apply a short jumper wire across the wiring terminals.
  • RF range values are based on ideal conditions in open space. Actual results will vary for every installation. In general, wireless signals can be diminished or impeded by RF interference, concrete walls, large appliances, etc.
