LA Series 4000

Time Delay "OFF"

The Time Delay “OFF” Controller operates as a single output controller where the application requires restrictive activation of a utility with a delay “OFF” after first activation.

This unit is ideally suited for shower units in correctional facilities or drug testing facilities where operation or use of the showers or lavatory facilities will be limited to specific time periods, and where operation “ON” is established by authority.  Style 44’s use includes wash-down systems where predetermined cycled operation is required but with capabilities for short cycle activation on demand.

The delay “OFF” relays are housed in a remotely located enclosure with a screw-on cover.  The active “ON” switching incorporates a momentary key-switch for Operation and a push-button “STOP” switch for immediate deactivation and are mounted on a stainless steel wall plate.



Operation - Key Switch:  Momentary switch for an “ON” Cycle.

Push Button Switch: Contacts disengage the system requiring re-keying to active “ON”.

Wall Panel: Brushed Stainless Panel W/ vandal resistive hardware.

(labeling   “OPERATE” – “ON”  -  “STOP”)

Switch Wall Box: Powder coat W/ hardware for flush mounting.

Controller Wall Box: Powder Coat W/ solid cover and mounting hardware.

(Operating switches can optionally be mounted on the enclosure panel whereby the wall panel & box are omitted.)

ISIMET Utility Controllers and Companion Enclosures
Two Hour Fire Rating

UL Test #1479

All ISIMET Utility Controllers, Enclosures and Accessories can be certified for two-hour fire rating.  Working closely with the industry leader in fire rated materials, ISIMET can offer our enclosures with a one-half inch fire rated blanket.  This blanket that is adhered to the outer surface of the enclosure will enable the installer to incorporate the ISIMET product into a fire rated wall without the need for additional blanket or other rated material.

To specify a unit as “Fire Rated” use the following nomenclature:

Add to the ISIMET Part Number:  Prefix “F2” for all Utility Controllers, Companion Enclosures and Accessories.  Model numbers are for example only.

UtC-F2-12X9 indicates a four-circuit Utility Controller with fire blanket.

LA-F2-1212 indicates a wall mounted LA Series with fire blanket.

FLA-F2-2235 indicates a wall mounted FLA Series with fire blanket.
