Seco-Larm Curtain Sensor. Length: 22??", With Four Photoelectric Beams. Range: Up To 25Ft Outdoor And 50Ft Indoor. No/nc Relay Output, Anti-Tamper Circuit, And Led Alignment Indicator. Black Enclosure. - E-9622-4B25

Connecting Multiple Curtain Sensors Several units can be connected together in parallel to the same power supply output and alarm input of an alarm control panel. Tamper Protection The receiver and the transmitter both have a tamper switch on one end to protect against someone attempting to open the unit. However, there is no separate tamper output to the alarm control panel. Instead, the alarm output is triggered if the cover of the end cap with the tamper button is removed, if the transmitter or receiver is moved out of alignment, or if power is disconnected. Running the Wires Run four wires (2 x power and 2 x alarm signal) from the alarm control panel to the receiver of the curtain sensor. 4 Conductor, 22-Gauge Shielded Cable is strongly suggested. Weatherproof Construction Ingress Protection (IP) is a rating for electronic products as it relates to the amount of sealing they have against the entry of solid and liquid objects. Complete details of this standard can be obtained from the IEC. This uniform and widely acknowledged classification system provides equipment designers and specifying agents with a convenient and reliable method of comparing relative levels of sealing between competing (connector) products. In its simplest form, the classification system consists of the letters "IP" followed by two separate digits, which denote increasingly greater sealing from solid objects and from water. The Enforcer Curtain / Barrier Sensor has a rating of IP65. The number '6' refers to the degree of protection against access to hazardous parts and ingress of solid objects, 6 is the highest rating at "dust tight; complete protection against contact". The number '5' refers to the degree of protection against the ingress of water. 5 is one of the highest levels of protection, "Water projected by a nozzle against enclosure from any direction shall have no harmful effects."
