Listed for operation at the broad- temperature range in the industry ( to 131 the 6424 can be used in or warehouse applications to provide early warning in environments temperature extremes exceed the capability of spot-type smoke detectors. 6424 consists of a transmitter and receiver with separate alarm and trouble which distinguish between a percentage of signal blockage and a total block. Four alignment LEDs on the front of each unit indicate signal to ease alignment. The Remote Test Station with alarm LED indicator, RTS451, is an accessory that mounts to a standard single gang box and test and reset the Beam Detector from a remote location. Specifications Specifications (Receiver) Specifications projected beam type smoke detector be a 4-wire 24 VDC device to be with U.L. listed separately supplied control panels only. Unit shall be to U.L. 268 and shall consist of a transmitter and receiver capa- of being powered separately or The detector shall operate in a short range (30 ft.) or long (100 ft.) mode. The tempera- range of the beam shall be to The detector shall feature a bank four alignment LEDs on both the and transmitter that are used to proper alignment of the unit with- special tools. The beam detector feature automatic gain control will compensate for gradual signal from dirt accumulation on The unit shall include both ceil- and wall mounting brackets.
