The 1151E ionisation smoke detectors use state-of-theart sensing chambers and are designed to provide open area protection. 1151E can only be used with M/EM Series control panels from Morley-IAS or alternative compatible panels. The ability to plug these detectors into a variety of base options extends panel compatibility and application flexibility. The 1151E has remote LED annunciator capability as well as two integral LED's to provide local visible indication of detector status. Once the detector senses smoke, it latches in alarm and remains in this condition until it is reset by a momentary power interruption. The 1151S detector includes a tamper resistant feature that prevents removal from the base without the use of a tool. 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.
