System Mounting

IMPORTANT NOTESThe system should be mounted at EYE LEVEL.

Care must be taken to ensure the system and all protruding components are clear of all enclosure accesses (doors and covers) and conduit, pipe, tubing or cable entries.

LH, RH, TM and BM configurations are intended for mounting adjacent to the protected enclosure.

Determine the mounting configuration for your application using the diagrams on page 8.

Remove and save the manila envelope (containing the enclosure warning nameplate) which may be taped to the System mounting bracket.

Although all systems are factory tested and calibrated, we strongly suggest a bench test of basic functions prior to installation.

Mounting LH, RH, TM, & BM Configurations1. Determinethemountingconfigurationforyourapplication

• Thealarmmusttakeitsmeasurementfromtheenclosureonly.

• Alarmslocatedinthehazardousareamustberatedforthearea.

• Valvescannotbeconnectedbetweenthealarmandtheenclosure.

IMPORTANT NOTE: NFPA 496 requires the use of an alarm or an indicator to detect the loss of safe enclosure pressure. In addition, the NFPA 496 requires that if an indicator alone is utilized, a protective gas supply alarm must also be installed between the last valve in the protective gas supply and the protected enclosure. Therefore, the protective gas supply to all Model 1011 systems must be equipped with the above mentioned protective gas supply alarm. Exception: Systems utilizing an EPSK or GPSK enclosure pressure loss alarm switch accessory will satisfy the above mentioned NFPA requirement.
