Model 4WRM
Install a 4WRM into a 2WRLT or 2WRB base to function as a 4WRB as follows:
1.Remove resistors connected to terminals 2 to 3 and 3 to 4 if converting the 2WRLT base.
Remove the 2WRM if converting the 2WRB.
2.Insert the 4WRM into the base.
3.Secure into position by twisting clockwise as shown in Figure 7.
4.Wire the 4WRM and base according to Figure 5.
5.Secure the wire under terminals 3 and 4 shown in Figure 7.

MECHANICAL RETROFIT ADAPTER (MA 001)
The MA-001 (P/N 70-501000-003) is used to allow all old style Fenwal bases (Series 70 201000-XXX) to accept the CPD-705X, PSD-715X and THD-
705X detectors. No rewiring is required to retrofit the base. Install as follows:
1.Align the components as shown in Figure 8.
2.Mate the MA-001 to the existing base and twist clockwise to lock in.
3.Mate the new detector to the MA-001 and twist clockwise to secure.

DETECTOR TESTING AND SENSITIVITY METERING
FREQUENCY
Testing shall be performed upon installation of the detector and once a year thereafter as stated in NFPA-72 latest edition. Smoke Detector sensitivity
shall be metered within one year of installation and every alternative year thereafter as stated in NFPA 72.
The Authority having jurisdiction may
dictate which test to perform.
GO-NO GO TEST FOR SMOKE (CPD & PSD) DETECTORS
Equipment Required
Test Magnet P/N 06-117883-001, OR
Canned Smoke
Test Method
1.
Disengage Alarm Signal Devices, Releasing Devices and Extinguishing Systems prior to performing the following test.
2.Use extreme caution when using magnet in EDP Facilities.
To be safe, notify EDP management of the intent to use a magnet in their facilities.
3.After powering the detector head for approximately 1 minute, check to see that the indicator LEDs flash.
Failure to flash indicates a
nonfunctioning detector or faulty wiring. Recheck wiring and replace detector head if necessary.
