SPECIFICATIONS / FINISHES

Suggested Specification

Closer for -- doors shall be electromechanical closer-holder. Hold-Open to be achieved by electric solenoid locking of closer arm slide in its track. Track, arm, slide (and) solenoid (and integral smoke detector) to be contained in a single aluminum extrusion 1-1/2" (38mm) high, 1-1/2" (38mm) deep. Closer shall be door mounted. Track and hold-open mechanism shall be surface mounted to the frame face for application on the pull side of the door and frame soffit mounted for application on the push side of the door.

Single point Hold-Open shall be selective through a range of 85º to 110º. Hold-Open point to be achieved by adjustment of a telescoping closer arm.

Closer shall be hydraulic with full rack and pinion enclosed in a cast aluminum alloy shell. Hydraulic fluid shall be non-gumming and non-freezing. Closer shall have two non-critical valves to independently regulate sweep speed and latch speed. It shall have an adjustable backcheck cushioning valve (and an adjustable backcheck positioning valve). All valves shall be adjustable with a hex-key. (Closer shall have spring power adjustment to permit 50% increase in closing power .) Closer to be enclosed in a molded (Full) (Slim Style) cover.

(Master units to have an integral smoke detector with dual ionization chamber. Master units integral smoke detector shall have latching alarm and reset switch.) (Slave units to be controlled by the master unit.) (Support units to be controlled by U.L. Listed Smoke Detection Equipment.) Units to be fail safe and close the door during any interruption to the electrical power. The hold-open solenoid coil shall have a maximum amperage draw of (.090 Amps at 24 volts) (.035 Amps at 120 volts). Unit shall have a switch to permit testing of the releasing device function without alarming the system.

All wiring connections shall be made without the need of wire nuts or soldering.

Master unit(s) shall require a (24VAC-DC) (120VAC, 60Hz.) (24VAC-DC & 120VAC, 60Hz.) power input.) (Slave unit(s) shall require a 24 Volt power input from the Master Unit. Support unit(s) shall require a (24VAC-DC) (120VAC. 60Hz.) power input. Supplier to coordinate electrical requirements with electrical and alarm system engineers. Wiring (and conduit) by others.

Executive Door Holder-Release "PT-RF"

Power input to unit shall be 120 Volts AC at 60 Hz. Unit hall have an integral radio frequency receiver. When the door is held open. the signal from a (hand-held) (desk mounted) transmitter shall interrupt power to the unit and release the door from hold open. Power to the transmitter shall be provided by a standard 9 Volt alkaline battery. [(P)7700PT-RF] [(P)8200PT-RF] [(P)8300PT-RF][(P)8400PT-RF] [(P)8500PT-RF].
