Installation <br />Single -stage Signature Series fire alarm manual pull stations mount to North American 2'/2 inch (64 mm) deep 1-gang boxes. <br />Two stage presignal (270P) models require 11/2 inch (38 mm) deep 4-inch square boxes with 1-gang, %cinch raised covers. Openings <br />must be angular. Rounded openings are not acceptable. Recommended box: Steel City Model 52-C-13; in Canada, use Iberville Model CI- <br />52-C-49-1/2. <br />All models include terminals are suited for #12 to #18 AWG (2.5 mm2 to 0.75 mm2) wire size. EDWARDS recommends that these fire <br />alarm stations be installed according to latest recognized edition of national and local fire alarm codes. <br />Electronic Addressing: The loop controller electronically addresses each manual station, saving valuable time during system com- <br />missioning. Setting complicated switches or dials is not required. Each station has its own unique serial number stored in its on -board <br />memory. The loop controller identifies each device on the loop and assigns a "soft' address to each serial number. If desired, the stations <br />can be addressed using the SIGA-PRO Signature Program/Service Tool. <br />Compatible Electrical Box <br />Key-Lotch <br />Cover Release <br />Compatible Electrical Box <br />- <br />Cover <br />v4 Release <br />Screw <br />Bank Back <br />Q Backup <br />A Plate <br />�ewe <br />9wkch Switch <br />.Op <br />Z <br />Glare Rod <br />Glass Rod <br />Releaee Lever <br />OPEN �6 <br />Figure 1.
