6.2.9.3 Connecting Wired Zones
The Takeover Module determines the presence and status of each zone based on the
zone’s loop resistance. Each wired zone is supplied with a 5.1K Ohm resistor installed.
Before using the prewired zone, close all the contacts in the zone and confirm that the
zone resistance is between 2.2K and 6K Ohms.
1. Remove AC power from the existing wired panel
2. Remove leads from battery on existing wired panel
3. With power removed, disconnect the hardwired zones from the existing panel
4. Remove the supplied resistor from the zone(s) connector to be used.
5. Each hardwired zone wire pair goes to a pair of connectors in the Takeover
Module. (See Figure 67.)

6.2.9.4 Powering the 915MHz Two-Way Keypad
The Takeover Module can be used to power the 915MHz Two-Way Keypad. This is
done by using an existing pair of wires to the previous wired keypad location.
To power the two-way keypad using the takeover module, do the following:
1. Remove AC power from the existing wired panel
