Manual Call Points
Overview SIGI-271 Fire Alarm Call Points are part of GE’s Signature Series sys-tem. These integrated assemblies feature the familiar KAC Installers’ Series Call Point packaged with Signature Series intelligent address-able/ analogue interface electronics.
In all 271 Series Call Points, the switch is held off by the edge of the glass. When the glass is broken by pressing directly on it, the switch is released and an alarm sent to the Signature loop controller. A protective plastic coating on the glass prevents operator injury and inhibits the release of glass fragments.
Each Signature Series Call Point constantly runs self-checks to provide important maintenance information. The results of the self-check are automatically updated and permanently stored in the Call Point’s non-volatile memory. This information is accessible for review any time at the control panel, PC, or by using the SIGA-PRO Signature Program/Service Tool.
The information stored in the Call Point’s memory includes:
· Call Point serial number, address, type code.
· Manufacture date, hours of operation, last maintenance date.
· Number of recorded troubles, alarms, time and date of last alarm.
· Up to 24 possible trouble codes that may be used to specifically diagnose faults.
The Signature loop controller learns where each device’s serial number address is installed relative to other Signature devices on the circuit. The loop controller
Intelligent Device with Integral Microprocessor
All decisions are made at the Call Point to allow lower communi-cation speed. Lower communication speeds are less sensitive to line noise; twisted or shielded wire is not required.
Automatic Device Mapping
Each Call Point transmits wiring information regarding its loca-tion with respect to other Signature devices on the circuit. Electronic Addressing
Addresses are downloaded from a PC, or the SIGA-PRO Signature Program/Service Tool. There are no switches or dials to set.
Permanently stores serial number, type of device, and job num-ber. Automatically updated with historic information. Stand-alone Operation
Call Point can input an alarm even if the loop controller’s polling interrogation stops.
Alarm LED Red led flashes to show “alarm” state.
