Edwards EST SIGA-270 / SIGA-278 Manual Call Points

The SIGA-270 and SIGA-278 series Manual Pull Stations are part of EDWARDS’s Signature Series system. The SIGA-270 Fire Alarm Manual Pull Stations feature our very familiar teardrop shape. They are made from die-cast zinc and finished with red epoxy powdercoat paint complemented by aluminum colored stripes and markings. With positive pull-lever operation, one pull on the station handle breaks the glass rod and turns in a positive alarm, ensuring protection plus fool-proof operation. Presignal models (SIGA-270P) are equipped with a general alarm (GA) keyswitch for applications
where two stage operation is required. The up-front highly visible glass rod discourages tampering, but is not required for proper operation.
