Overview
SIGI-271 Fire Alarm Call Points are part of Edwards’s Signature Series system. These integrated assemblies feature the familiar KAC Installers’ Series Call Point packaged with Signature Series
intelligent addressable/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 con- troller. 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 keeps a “map” of the Signature Series devices connected to it.

Standard Features
• Intelligent Device with Integral Microprocessor

All decisions are made at the Call Point to allow lower commu-
nication 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 location 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 dialsto set. 

• Non-volatile Memory

Permanently stores serial number, type of device, and job number. 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.

• Designed For High Ambient Temperature Operation

Install in ambient temperatures up to 120 °F (49 °C).

• Flush or Surface Mount

• Optional Markings Available

Glass inserts with multiple languages are available.

• Designed To ISO 9001 Standard
Manufactured to strict international quality standards.
