E-PHD Optical/Fixed Temperature Detector
This intelligent analog device houses an optical sensing chamber that detects smoke, as well as a fixed-temperature sensor that detects heat. The detector analyzes data from both sensors to determine when an alarm is initiated.

The detector continuously adjusts its sensitivity based on fluctuating environmental conditions such as the presence of dirt, smoke, humidity, or changes in temperature, and notifies the panel of any changes in sensor sensitivity. When the detector has adjusted its sensitivity to its maximum limit, it issues a dirty sensor warning, allowing enough of a margin for maintenance personnel to clean the detector before it goes into trouble condition.

The E-PHD is capable of performing comprehensive self-diagnostics and storing the results.

The E-PHD combines the suitability of optical sensing for slow burning fires with the sensitivity of fixed-temperature detection for fast flaming fires to arrive at a solution that responds reliably to the widest range of fire types. A sophisticated algorithm processes data from both sensors over time so that an alarm is only reported when conditions precisely match the signature of a fire. This eliminates the shortcomings of single-sensor optical and heat detection, and significantly reduces the risk of nuisance alarms.

E-HD Fixed Temperature Heat Detector
This intelligent analog device provides a 135°F (57°C) fixed-temperature heat sensor for the detection of heat due to fire. The heat sensor monitors the temperature of the air and determines whether an alarm should be initiated.

The E-HD is capable of performing comprehensive self-diagnostics and storing the results.
Thanks to its advanced thermistor technology, the E-HD detector is ideal for sensing fast, flaming fires and for applications where smoke detection is inappropriate. It is particularly well-suited to areas such as laundries and industries where fluctuations in ambient temperature is expected.

E-PD Optical Smoke Detector
This intelligent analog device uses an optical sensing chamber to detect smoke. The detector analyzes data gathered by the sensor to determine when an alarm is initiated.

The detector continuously adjusts its sensitivity based on fluctuating environmental conditions such as the presence of dirt, smoke, humidity, or changes in temperature, and notifies the loop controller of any changes in sensor sensitivity. When the detector approaches its preset sensitivity threshold, it issues a dirty sensor warning, allowing enough of a margin for maintenance personnel to clean the detector before it goes into trouble condition.

The E-PD is capable of performing comprehensive self-diagnostics and storing the results.

Thanks to its high-performance optical sensing chamber, the E-PD responds quickly and reliably to a wide range of fire types, especially slow burning fires fuelled by combustibles typically found in modern multi-use buildings. The E-PD detects extremely small particles and triggers an alarm at the first sign of smoke.

LED Indication
The detector provides a bicolor LED that shows its status.
Normal: Green LED flashes
Alarm/active: Red LED flashes

B4U Standard Base
The B4U Analog Standard Detector Base features twist-and-lock detector installation and is compatible with with E-Series analog detectors. The base does not require a separate address because it shares the address of the device it is connected to.

IB4U Isolator Detector Base
The IB4U Analog Isolator Detector Base is designed to prevent an entire communications loop from being disabled when a short circuit occurs. This is accomplished by isolating the part of the loop containing the short from the remainder of the circuit. These bases automatically restore the entire loop when the cause of the short circuit is corrected. The base can operate as an independent local alarm or as part of a zone.

RB4U Relay Detector Base
The RB4U Analog Relay Detector Base is designed to add relay functionality to the listed compatible detectors. Form C latching relay contacts are included for the control of appliances such as door closers, fans, dampers, etc.

SB4U Audible (Sounder) Detector Base
The SB4U is designed to add an audible output function to compatible detectors. The base can operate as an independent local alarm, or as part of a zone or system alarm with synchronized audible output.

Depending on the system supporting the device loop, the base can operate as follows:

• It can follow the state of the device it supports


• It can be controlled and configured for other operating modes through programming.

The SB4U is field-configurable for output tone (steady or temporal) and output volume (low dBA or high dBA). The base must be connected to a continuous voltage whether the output tone is set to steady or temporal. The base does not require a separate address because it shares the address of the device it is connected to.
