The Edwards SIGA-IM2 Isolator 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 EM312SR module enables control of external devices in fire alarm systems through a supervised input, a supervised output for audible/visual indicators, and a volt-free relay output for devices such as electromagnets. It also includes an external supervised voltage input, a short-circuit isolator, three multicolor LEDs to indicate channel status, and automatic addressing via serial number. Compact and versatile, it is ideal for installations requiring maximum reliability.
The EM500 module is designed to control synoptic panels within loop-based systems. Consisting of two units supplied together, it includes the EM500 module, with 8 configurable LED outputs and 5 multifunction inputs, and the EM500-EXP expansion module, which adds 24 configurable LEDs and requires a 24V DC auxiliary power supply. Ideal for remote visualization of system status, it allows for flexible configuration and precise visual signaling.
Wall mount addressable visual/audible-alarm signaller, IP65 protection grade.
Volume, flash intensity and audio sequences selectable (and diversified according to circumstances) between the 14 tones
(and 16 messages in 8 different languages for the versions with voice functions) available on board the device. For models
with the voice alarm function, it is also possible to customize tones/voice messages by means of the EDRV2000.
The device is powered via the loop but is equipped with terminals for an optional separate power input.
Available in red or white casing
Addressable base with audible signalling, low-consumption, in black and white casing
The Esser 805590 Detector Base is a high-quality mounting accessory designed for seamless integration with IQ8Quad and ES Detect series fire detectors. Built for reliability and ease of installation, this base ensures secure detector mounting while maintaining uninterrupted loop communication in fire alarm systems.
Automatic heat detector with a single thermistor to sense the air temperature around the detector. Fast semiconductor sensor guarantees reliable detection of fires with rapidly rising temperatures and integrated fixed temperature function for the detection of fires with slowly rising temperatures. Ideal for sensing in environments that are dirty or smoky under normal conditions, as well it is unaffected by wind or atmospheric pressure. Intelligent fire detector with decentralized intelligence, automatic function self-test, CPU failure mode, alarm and operating data memory, alarm indicator, soft-addressing and operating indication.
The Esser 802382 Smoke Detector with Integrated Sounder is an advanced fire detection device designed to provide early warning and local audible alerts in case of smoke detection. Combining a high-sensitivity optical smoke sensor with a built-in sounder, this unit ensures faster response and enhanced safety, especially in areas where immediate local notification is critical.
The Esser 807224RR is an integrated acoustic and optical signaling device designed for the esserbus-PLus loop. Part of the IQ8Alarm Plus family, it combines a high-output electronic sounder with a high-intensity LED beacon. The “RR” designation indicates a Red housing with a Red flash (Visual Alarm Device). This device is fully synchronized across the entire loop, ensuring that all sounders and beacons activate in perfect unison to avoid confusion during evacuations. It is loop-powered and software-configurable, allowing for various tones and flash frequencies to be set via the control panel without changing hardware.
The Esser by Honeywell IQ8Quad Optical Smoke Detector (Model 802371) is an intelligent addressable optical smoke detector designed for the early detection of slow-burning and smouldering fires. Utilizing the proven light scatter detection principle, the detector delivers reliable and accurate smoke detection while minimizing false alarms. Equipped with decentralized intelligence, an integrated short-circuit isolator, automatic self-testing, alarm memory, and soft addressing, the IQ8Quad 802371 ensures high system reliability and simplified maintenance. It is fully compatible with Esser esserbus® and esserbus®-PLus intelligent fire alarm systems, making it an ideal solution for commercial, industrial, healthcare, and institutional fire protection applications.
The 804971 ESSER refers to a compact, small, red manual call point with a resettable element, designed for use in fire alarm systems ¹. It’s part of the IQ8MCP series and features a flat design, low power consumption, and plug-in connection terminals
Module in plastic protective housing for connection of an esserbus / esserbus-PLus loop. Mixed operation of esserbus and esserbus-PLus is possible in a fire alarm panel. Up to 18 loops can be realized depending on the extension of the alarm panel and/or on the number of available module slots.
Up to four modules without galvanic isolation can be used in the fire alarm panel. If more than 4 loop modules are used in a panel, modules with galvanic isolation (GI) are necessary to be used from the fifth loop module onwards. Mixed operation of the modules with/without galvanic separation within one control panel is easily possible. Modules are locked mechanically without screws in the slots, just quick & easy. HOT PLUGGING and automatic recognition of modules just by Plug & Play, makes start-up and maintenance easy to handle
