Commercial Operators

Name: Fire Sentinel fail-safe release device
Brand: Overhead Door

Jackshaft, trolley, and slide operators with the controls and safety devices each door needs.

We size, install, and service every commercial operator from Century Avenue across 11 Maryland counties using our own technicians. The operator turns a door into a system. We service the operators already on your building, no matter who installed them. The complete Overhead Door line is here: the heavy-duty RHX, the standard-duty RSX, the medium-duty RMZ, the CDX for counter doors, and the Fire Sentinel release.

The RHX warranty card covers parts for two years from installation. The RSX and CDX cards cover two years or 20,000 cycles, whichever comes first. Labor is excluded on all three. A rolling service door or Thermacore sectional door bought and installed with its RSX, RMZ, or RHX operator carries a system warranty of three years or 20,000 cycles.

RHX heavy-duty industrial operator

Models RHX and RHX Explosion-Proof

The RHX is the heavy-duty operator of the line. It is built for the most stringent applications and the largest constant loads. Mountings cover the door: standard, side mount, or dual trolley on a sectional door; side or center mount jackshaft with chain or direct coupling; and hoist units on rolling steel at the front of hood, top of hood, bench, or wall. Open drip-proof motors run 1/2, 3/4, 1, and 3 hp, single or three phase. Voltamatic units take 115/208/230 V or 208/230/460 V, with a separate 575 V unit. The primary worm gear in an oil bath, a chain secondary, a 24 V DC disc brake, and Progressive Braking soft stop carry sectional doors up to 1,650 lb at 1 hp, or 3,696 lb with the 14 RPM direct couple kit at 3 hp. The RHX Explosion-Proof is the same operator with FM approved motors for Class I Group D and Class II Group F and G locations, dynamic braking, and a NEMA 7/9 enclosure. It is UL 325 2010 compliant. It is the operator our crews hang on the largest rolling steel and Thermacore doors around Baltimore.

RSX standard-duty commercial operator

Models RSX and RSX Egress

The RSX is the standard-duty operator, rated for peaks of 60 cycles per hour. It is the operator our technicians put on most dock doors around Baltimore. It mounts as a trolley, side mount, or dual trolley on a sectional door; a side or center mount jackshaft with or without a hoist; and on rolling steel at the front of hood, top of hood, bench, or wall. Motors are 1/2, 3/4, and 1 hp, single or three phase. They run on Voltamatic voltage freedom, driving through an auto-tensioning SuperBelt primary and a chain secondary with a 24 V DC disc brake and Progressive Braking. LimitLock limits hold position through manual operation and power loss. The receiver learns 250 CodeDodger transmitters. Timed close runs 0 to 5 minutes. Options range from NEMA 4/4X motors to Commercial WiFi and light curtains. The RSX Egress releases a 670 or 671 grille to fully open on an alarm, push button, or loss of power. The RSX Fire Door operator is FM approved for fire door assemblies, featuring 24-hour battery backup and floor-level auto-reset after a drop test. It is UL 325 2010 compliant.

RMZ Z Series medium-duty operator

Models RMZ Jackshaft and RMZ Trolley

The Z Series RMZ is the medium-duty operator for doors with a limited duty cycle, rated at 15 cycles per hour. The line includes the RMZ Jackshaft for rolling doors and the RMZ Trolley for standard-lift sectional doors under 50 cycles a day. A 1/2 hp, 120 V AC capacitor start/run motor with built-in thermal protection can be replaced without resetting the limits. It drives through a self-tensioning SuperBelt primary and chain secondary with a 24 V DC disc brake and an adjustable friction clutch. It handles doors up to 16 ft high, 580 lb rolling, or 620 lb sectional. The trolley runs 11.5 in per second on the same 2 in rail the RSX and RHX use. LimitLock limits, a maximum run timer that learns the door, a 16-character LCD with cycle count, an internal CodeDodger receiver for 250 transmitters, a programmable mid-stop, and a pull-cord release are standard. The modular board takes Timer Close, Auxiliary Output, Edge Sensing expansions, and the Commercial WiFi module. It is UL 325 listed and pre-wired for monitored entrapment devices.

CDX counter door and counter fire door operator

Model CDX

The CDX is the light-duty operator for counter doors and counter fire doors in factories, schools, concession stands, hospitals, cafeterias, and retail. It is rated at 4 cycles per hour at 70 ft-lb per second. It mounts front of hood with a chain and sprocket coupling. The 1/2 hp, 115 V single phase intermittent-duty motor has high starting torque and an automatic reset thermal overload on a NEMA 42 open drip-proof frame. It drives a helical primary and hardened bevel secondary for doors up to 500 lb. LimitLock linear limits stay synchronized with the door through a release. The 16-character backlit LCD carries a cycle counter, a maximum run timer that stops the close if the learned run time is exceeded, and on-board open, close, and stop functions. The counter fire door model adds a spring-loaded release for a fusible link or Fire Sentinel, and a centrifugal drum governor that controls drop speed on a manual release. A hand crank with electrical interlock and radio hookups are options. It is UL 325 2010 listed. The Timer to Close Module is not offered on counter fire doors.

Fire Sentinel fail-safe release device

Models FSAX24V, FSBX24V, FSBX120V, FSCX24V and FSCX120V

Fire Sentinel is the fail-safe time-delay release device that directs a rolling fire door or counter fire door to close in an emergency. It is fail-safe as NFPA 80 defines it. Testing, reset, and trouble indication happen at floor level. The device recognizes a closed door and inhibits its release. Five models are available in 24 V DC or 120 V AC: the FSAX, and the FSBX and FSCX with 24-hour battery backup. Options include an alarm on power loss. The FSCX includes a standard sounder and strobe, and stops on obstruction with an optional sensing edge. The delay on alarm is 10 seconds. It is adjustable to 20 or 60 seconds where the authority having jurisdiction allows, with relay outputs for alarm and trouble status and support for 2 or 4 wire smoke detectors. It is UL 864 listed for the United States and Canada, NFPA 72 compliant, FM approved, and compatible with UL 325 compliant operators. The maximum release load is 20 lb.
