General The SIGA-270 and SIGA-278 series Manual Pull Stations are part of EST’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. EST’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. Features • Traditional familiar appearance SIGA-270 models feature our familiar teardrop design with simple positive pull action and sturdy die-cast metal body. • One stage (GA), two stage (pre-signal), and double action models SIGA-270 models are available for one or two stage alarm systems. The single stage double action SIGA-278 features a rugged Lexan housing with keyed reset mechanism. • Break glass operation An up-front visible glass rod on the SIGA-270 discourages tampering. • Intelligent device with integral microprocessor All decisions are made at the station allowing lower communication speed while substantially improving control panel response time. Less sensitive to line noise and loop wiring properties; twisted or shielded wire is not required. • ADA Compliant Meets ADA requirements for manual pull stations. • Electronic Addressing with Non-volatile memory Permanently stores programmable address, serial number, type of device, and job number. Automatically updates historic information including hours of operation, last maintenance date, number of alarms and troubles, and time and date of last alarm. • Automatic device mapping Each station transmits wiring information to the loop controller regarding its location with respect to other devices on the circuit. • Stand-alone operation The station inputs an alarm even if the loop controller’s polling interrogation stops. • Diagnostic LEDs Status LEDs; flashing GREEN shows normal polling; flashing RED shows alarm state. • Designed for high ambient temperature operation Install in ambient temperatures up to 120 °F (49 °C).
