Velociti® Series ATD-L2F, ATD-RL2F Description Addressable Thermal Sensor The Gamewell-FCI Velociti® Series, addressable plug-in thermal sensors with integral communication provide features that surpass conventional sensors. Point ID capability allows each sensor’s address to be set, providing exact locations for pinpointing alarm locations and for selective maintenance. ATD thermal sensors use an innovative thermistor sensing circuit to produce 135°F/57°C fixed-temperature (ATD-L2F). The ATD-RL2F provides a combination 15°/minute rate-of-rise with 135° fixed thermal detection that is included in a low-profile package. The ATD-HL2F provides fixed high-temperature detection at 190°F/88°C. These thermal sensors provide cost-effective, addressable property protection in a variety of applications. The Velociti® Series uses a communication protocol that substantially increases the speed of communication between the sensors and Gamewell-FCI analog addressable fire alarm controls. These devices operate in a grouped fashion. If one of the devices in the group has a status change, the panel’s microprocessor stops the group poll and concentrates on the single device. The net effect is response speed up to five times greater than earlier designs. ATD-L2F Features • Sleek, low-profile design • Visual rotary switch addressing • Built-in functional test switch activated by an external Installation ATD plug-in sensors use a separate base to simplify installation, service, and maintenance. A special tool allows maintenance personnel to plug-in and remove sensors without using a ladder. Mount the base on a box which is at least 1.5" (3.8 cm) deep. Suitable mounting base boxes include: • 4.0" (10.2 cm) square box. • 3.5" (8.9 cm) or 4.0" (10.2 cm) octagonal box. • Single-gang box (except relay or isolator base). • With B501BH or B501BHT base, use a 4.0" (10.2 cm) square box. • With B224RB or B224BI base, use a 3.5" (8.9 cm) octagonal box, or a 4.0" (10.2 cm) octagonal or square box. NOTE: Because of the inherent supervision provided by the SLC, end-of-line resistors are not required. Wiring “Ttaps” or branches are permitted for Style 4 (Class “B”) wiring. magnet • Bicolor LEDs flash green whenever the sensor is addressed, and light steadily red on alarm* • Optional relay, isolator, or sounder bases • Low standby current • Addressable communication • Stable communication technique with noise immunity • Optional remote, single-gang LED accessory (RA-400Z) • Suitable for installation in ducts Note: *Only the red LED is operative in panels that do not operate in Velociti® mode.
