Shat-R-Shield Ironclad INH Zero-Watt Self-Luminous Exit Sign

Purpose: Shat-R-Shield Ironclad® Zero-Watt INH is a self-luminous EXIT sign for institutional and correctional egress locations where an illuminated sign is needed without a wired electrical supply or backup battery. Its sealed tritium light source does not rely on building power. This is an EXIT identification device, not an emergency area luminaire.

Catalog reference: INH-10-1. This is a base model reference, not a fully specified manufacturer ordering code. Confirm the complete MPN, service-life rating, sign-face count, legend color, finish and mounting before ordering. The displayed price is for the catalog's base configuration only.

Buyer questions

Does Zero-Watt need electrical wiring or a battery?

No. Its sealed tritium source makes the EXIT legend self-luminous.

Is this an emergency light for illuminating a hallway?

No. It identifies the exit. Specify a separate emergency luminaire, such as SRSEM, where the egress path needs illumination.

How do I choose a sign configuration?

Specify quantity, face count, legend color, finish, location, mounting and required remaining service life. Security Pro USA must confirm the full manufacturer MPN before accepting an order.

Can a used tritium EXIT sign go in ordinary trash?

No. Unwanted tritium signs require transfer to an appropriately licensed recipient; follow the applicable NRC or Agreement State procedures and manufacturer return instructions.

Are there special purchasing requirements?

Yes. Manufacturers and distributors of tritium exit signs are subject to radioactive-material licensing rules. Supply and delivery are subject to confirmation of authorized distribution and required purchaser information.
