1151EIS conventional ion-04 for web
  • General
  • Feature
  • Specification

Model 1151EIS ionisation smoke detectors use state-of-the-art sensing chambers and SMD circuitry for maximum

reliability. These detectors are designed to afford open area protection and are for use in hazardous areas

where potentially explosive atmospheres are likely to arise (confirm classification of equipment required with

your responsible authority). 1151EIS detectors are designed to be used with compatible panels only and must

be used in conjunction with a compatible zener barrier or galvanic isolator.

Each detector has remote LED annunciator capabilility as well as two integral alarm LEDs to provide local visual

indication of detector status. Once the detector senses a fire, it latches in alarm and remains in this condition

until it is reset by a momentary power interruption.

Model 1151EIS smoke detectors include a tamper feature that prevents removal from the base without the use

of a tool. In addition, these detectors can be tested by activating an internal reed switch with a test magnet.

This test simulates smoke in the detector and performs a full check of the operating circuitry.

FEATURES:
