BASE OPTIONS
LOCKING FEATURE
The detector bases include a locking feature that prevents removal of the detector without using a tool. To eliminate this feature, break off the locking
tab shown in Figure 6, then install the detector. To remove the detector from the base once the locking feature has been activated, insert a small
screwdriver into the slot on the base to push the plastic tab while simultaneously turning the detector head counterclockwise (see Figure 6).
Use small bladed screwdriver

RELAY MODULES
Relay Modules are not recommended for stand-alone operation. The installation and allowable configurations of the 2-wire 2WRM and 4 wire 4WRM
are as follows:
Model 2WRM
Install a 2WRM into a 2WRLT base to function as a 2WRB as follows:
1.
Remove resistors connected to terminals 2 to 3 and 3 to 4 on the 2WRLT base.
2.Insert the 2WRM into the base.
3.Secure into position by twisting clockwise as shown in Figure 7.
4.Wire the 2WRM and base according to Figure 4.
5.Secure the wire under terminals 3 and 4 shown in Figure 7
