SIEMENS PE-11 CERBERUS SMOKE DETECTOR W/DB-11 BASE
The Siemens Building Technologies, Fire Safety PE-11 Series Photoelectric Smoke Detector, with its microprocessor controlled self-diagnostic circuitry, eliminates cumbersome sensitivity test equipment. It is the most advanced detector in its class. This detector employs a simple twist-in base for ease of maintenance and has a field cleanable/replaceable labyrinth and bug screen. This detector is highly immune to false alarm caused by deceptive phenomena such as dust or RF. The PE-11 has a full range of accessories available, including remote alarm indicator, remote sensitivity and alarm indicator, relay, audible base and a base adapter that allows use in older Fire Safety DB-3S Series bases.
The PE-11 is a two-wire, plug-in type photoelectric smoke detector which is compatible with Fire Safety PXL, SXL, and System 3 conventional systems and conventional loops of MXL Series, IXL and XL3 analog-addressable systems. The PE-11 contains an infra-red light emitting diode (LED) and a light sensing photodiode arranged so that under normal conditions, light from the LED does not reach the photodiode. When smoke enters the photo chamber, light emitted from the IR LED is scattered by the smoke particles and is received by the photodiode. The electrical signal produced by the photodiode is compared to a factory set alarm threshold, and if sufficient to indicate an alarm, latches the detector alarm. The PE-11 is reset at the control panel. The PE-11 has UL/ULC listed self-testing circuitry which tests the detector for defective operation or contamination every 7-8 seconds. If a problem is detected, the multicolor LED indicator will flash amber until the problem is corrected. The detector flashes green in normal operation. In the alarm mode, the detector will flash red every 2-3 seconds, and latch into alarm, alerting the control panel to the alarm condition. This microprocessor-controlled self-diagnostic system eliminates the need for external test meters or other equipment for detector testing and also alerts users to trouble conditions prior to periodic system checks
