The Control Relay Module and the Polarity Reversal Relay Module are part of the Signature Series system. They are intelligent analog addressable devices available in either plug-in (UIO) versions, or standard 1-gang mount versions.Control Relay Module provides a Form “C” dry relay contact to control external appliances such as door closers, fans, dampers etc. This device does not provide supervision of the state of the relay contact. Instead, the on-board microprocessor ensures that the relay is in the proper ON/OFF state. Upon command from the loop controller, the SIGA-CR/MCR relay activates the normally open or normally-closed contact.

The Edwards SIGA-IM2 Insolator Module is an addressable device that protects a signaling line circuit (SLC) from a to wire-to-wire short. The SIGA-IM2 module monitors line voltages and opens the data to detect a short, isolating the short between the two modules located closest to the short. The loop controller assigns an address to the SIGA-IM module. The module uses one detector address on the SLC.

• 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

Overview : 
The Signature Series SIGA-PHD detector brings advanced multisensor technology to a practical design that increases efficiency, saves installation time, cuts costs, and extends life safety and property protection capabilities. Continuous self-diagnostics ensures reliability over the long-haul, while environmental compensation helps reduce maintenance costs. The SIGA-PHD provides an optical smoke sensor and a rateof-rise heat sensor with a fixed temperature setting. Together these sensors efficiently detect smoldering fires, as well as fast flaming fires.

Overview :
SIGA-CC1/MCC1 Single Input Signal Modules and SIGA-CC2/ MCC2 Dual Input Signal Modules are part of EST's Signature Series system. They are intelligent analog addressable devices used for connecting, upon command from the loop controller, supervised Class B signal or telephone circuits to their respective power inputs. The power inputs may be polarized 24 Vdc to operate audible and visible signal appliances or 25 and 70 VRMS to operate audio evacuation speakers and firefighter’s telephones. The actual operation of the SIGA-CC1/MCC1 and SIGA-CC2/ MCC2 is determined by the “personality code” selected by the installer. It is downloaded to the module from the Signature loop controller during system configuration .
Standard Features :
• Single and Dual input (riser) select Use for connecting supervised 24 Vdc Audible/Visible signal circuits, or 25 and 70 VRMS Audio Evacuation and Telephone circuits to their power inputs.
• Ring-tone generator When configured for telephone circuits, the SIGA-CC1 generates its own ring-tone signal eliminating the need for a separate ring-tone circuit.
• Plug-in (UIO) or standard 2-gang mount UIO versions allow quick installation where multiple modules are required. The 2-gang mount version is ideal for remote locations that require a single module.
• Automatic device mapping Signature modules transmit information to the loop controller regarding their circuit locations with respect to other Signature devices on the wire loop.
• Electronic addressing Programmable addresses are downloaded from the loop controller, a PC, or the SIGA-PRO Signature Program/Service Tool; there are no switches or dials to set. Warnings & Cautions :
This module will not operate without electrical power. As fires frequently cause power interruption, we suggest you discuss further safeguards with your fire protection specialist.
Compatibility :
The Signature Series modules are compatible only with EST's Signature Loop Controller.

The Signature Series model SIGA-OSD Intelligent Optical Smoke Detector is an intelligent device that uses an advanced optical sensing chamber to detect smoke. The detector analyzes data from the sensing chamber to recognize smoke from a fire while ignoring nuisance non-fire sources and whether to initiate an alarm to the Fire Alarm Control Panel. LED indicator. The LED indicator (see Figure 1 below) displays the following states: • Normal: Green LED indicator flashes, no action. • Alarm/active: Red LED indicator flashes, evacuate the area.

The SIGA-CR is an addressable device used to provide one Form "C" dry relay contact to control external appliances (door closers, fans, dampers, etc.) or ...
