Installation
Single-stage Signature Series fire alarm manual pull stations mount to North American 2½ inch (64 mm) deep 1-gang boxes.
Two stage presignal (270P) models require 1½ inch (38 mm) deep 4-inch square boxes with 1-gang, ½-inch raised covers. Openings
must be angular. Rounded openings are not acceptable. Recommended box: Steel City Model 52-C-13; in Canada, use Iberville Model CI-
52-C-49-1/2.
All models include terminals are suited for #12 to #18 AWG (2.5 mm
2
to 0.75 mm
2
) wire size. EDWARDS recommends that these fire
alarm stations be installed according to latest recognized edition of national and local fire alarm codes.
Electronic Addressing: The loop controller electronically addresses each manual station, saving valuable time during system com-
missioning. Setting complicated switches or dials is not required. Each station has its own unique serial number stored in its on-board
memory. The loop controller identifies each device on the loop and assigns a “soft” address to each serial number. If desired, the stations
can be addressed using the SIGA-PRO Signature Program/Service Tool.
