A smoke detector is a device that senses smoke, typically as an indicator of fire. Commercial smoke detectors issue a signal to a fire alarm control panel .

• The Edwards SIGA-IM2 Insolator Module is part of GE Security's Signature Series system. This intelligent device enables part of the Signature data loop to continue operating should a short circuit occur. The module will be wired into a Class A data loop at any point. For example, if a fault occurs, the isolator cuts power to all devices beyond the isolator on the loop as follows:
• a short on the line critically causes all isolators to open within 23 msec.
• at 10 msec intervals, beginning on one side of the Class A circuit nearest the loop, the isolators close to providing the next isolator down the line with power.
• when the isolator next to the short closes, it reopens within 10 msec.

Once activated, the line fault isolator continuously checks the faulted side of the loop to determine if the short still exists. Also, when the fault is removed, is automatically restores the entire data loop to a normal condition. The microprocessor in every module gives at least three important benefits Self-diagnostics and History Log, Mapping, and Fast, Stable Communication

High quality loop powered device designed to alert building occupants of an emergency. Featuring fast and simple installation and control it is powered by the fire panel via the loop wiring. Control of the device is enabled using on-board switches or via the digital protocol using the control panel.

• The SIGA-278 series Manual Pull Stations are part of EST's Signature Series system. The SIGA-278 Fire Alarm Manual Pull Stations feature our very familiar teardrop shape. They are made from die-cast since and finished with red epoxy powder-coat paint complemented by aluminum colored striped 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.
