Gamewell-FCI 112-90033 beam smoke detector

• Make: Gamewell-FCI
• Model code: 112-90033
• Type: Smoke

Gamewell-FCI 112-90033 beam smoke detector incorporates both an infrared transmitter and a receiver in one wall-mounted unit. The infrared beam generated by the transmitter is reflected back to the receiver by way of a prism mounted on the opposite wall. The unit monitors the reflected beam for any obscuration caused by smoke. If a predetermined level of obscuration is reached, the beam detector initiates an alarm condition by a set of alarm dry contacts connected to the monitoring fire alarm control panel.
