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 powder-coat paint complemented by aluminum colored stripes and mark-ings.  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.EDWARDS’s double action single stage SIGA-278 station is a contemporary style manual station made from durable red colored lexan.  To initiate an alarm, first lift the upper door marked “LIFT THEN PULL HANDLE”, then pull the alarm handle.

Application:
The operating characteristics of the fire alarm stations are deter-mined by their sub-type code or “Personality Code”. NORMALLY-OPEN ALARM - LATCHING (Pesonality Code 1) is assigned by the factory; no user configuration is required. The device is configured for Class B IDC operation. An ALARM signal is sent to the loop controller when the station’s pull lever is operated. The alarm con-dition is latched at the station.
