Bosch DS435I motion detector

Single Beam Photoelectric Detector - 150 m (500 ft) range
- Friction lock optics
- Alarm retransmission
- Alarm memory (DS435i only)
- Inhibit wiring (DS435i only)

This single-beam photoelectric detector series consists of the surface mount DS415i and DS435i Detectors with their separate transmitters and receivers. The transmitter emits one invisible infrared beam to the receiver. If the beam is broken, the receiver signals an alarm.

<b>Alarm Memory</b>
Provides indication of stored alarms for use in multiple unit applications by latching the alarm LED at the receiver. Controlled by a switched voltage from the control panel.

Inhibit Wiring
Optional signal synchronization wire between transmitter and receiver. Prevents receiver from being activated by other sources such as another transmitter. Units must have a common ground connection.
