AT Signal Manual (P2502)
Narrowest signal on the market
Ideal for places with minimal clearance
Available in both LED and incandescent types
Available in pole, wall, hat and horizontal mounted configurations
Easy access to the transformer terminal block and the wiring from the back of the signal
All external protruding bolt threads have been eliminated to safeguard workers from cuts and injuries
The Type AT Color-Light Signal is a compact unit designed for rapid transit lines where clearances are very limited. The Type AT Signal, ideal for underground (tunnel) installation, is equipped
with a single optical lens since the efficiency of a doublet lens is not required in a dark environment. The 5" (12.7 cm) lens has a 3.5" (8.9 cm) focal length. The lens may be specified in red,
yellow, green, lunar white or clear. The modular design of the Type AT Signal permits multiple units to be bolted together, one atop the other, for the desired signal configuration. These signals
are typically supplied with mounting brackets for subway walls or ceilings. When space is limited, the AT is the perfect solution.
