Velociti^® Series
ATD-L2F, ATD-RL2F
Description
Addressable Thermal Sensor
The Gamewell-FCI Velociti^® Series, addressable plug-in
thermal sensors with integral communication provide fea-
tures that surpass conventional sensors. Point ID capabil-
ity 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 ther-
mistor sensing circuit to produce 135°F/57°C fixed-temper-
ature (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 address-
able 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.
Installation
ATD plug-in sensors use a separate base to simplify instal-
lation, 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 “T-
taps” or branches are permitted for Style 4 (Class “B”)
wiring.
