Intelligent 4D Multisensor Detector

Integrates three sensing technologies — Ionization, Photoelectric, and Heat — into one detector. Select alarm point for

any one of five sensitivity settings between 0.67 to 3.70% per foot. Heat detector alarms when it sees a 65° F (35° C)

increase in ambient temperature. Mounts to separate Standard, Relay, Isolator, or Sounder detector base.

Signature Series

Detectors and Bases

EST’s Signature series products are intelligent devices.

Intelligent devices have drastically lower communications

requirements than those of sensor type devices. Because of the

low Signature communications rate there are no special wiring requirements for Signature

circuits. This permits Signature devices to use existing wiring, as long as the wiring is in good

shape, free of electrical noise, When existing wiring is used, the Signature devices will

properly map the circuit, function as designed, and provide overall network response time

of less than three seconds. For new installations, twisted-pair wiring is all that is recom-

mended.
