Description

The System Sensor 1451 ionization type smoke detectors are specifically designed to meet the performance require- ments of fire detection/alarm systems. The 1451 ioniza- tion detector uses a state-of-the-art, dual unipolar sensing chamber. The detector is designed to provide open area detection and when installed in a two-wire base is com- patible with FCI fire alarm control panels. The detectors operation and sensitivity can be tested in place. The 1451 detector is of plug-in construction and plugs into the same base as the 2451 Series photoelectronic smoke detectors, making both models interchangeable. Bases are available for two-wire, four-wire, and 120 VAC four- wire operation. Two visible LEDs on each detector flash approximately every ten seconds indicating that power is being applied to the detector. The LEDs light steadily when the detector is in alarm. A remote LED annunciator is available as an optional accessory. The 1451 detector is Listed for use inside ducts up to a velocity of 1,200 FPM. Sensitivity testing is performed by placing a test magnet against the cover. The LED on the detector should light within 5 seconds. Field metering of detector sensitivity may be performed with the aid of a voltmeter and Test Kit, MOD 400R.

Mounting

  • On a 4 inch square box with or without plaster ring or supplied adapter. Minimum depth 1.5 inches.
  • On a 3.5 or 4 inch octagonal box. Minimum depth 1.5 inches.
  • On a single gang box. Min. depth 1.5 inches. Installation Place the detector into the detector base. Turn the detec- tor clockwise until the detector locks into place. To use the tamper-proof feature, break the smaller tab on the scribed line in the tamper proof tab located on the detector mounting bracket. Install the detector. To remove the detector from the base when using the tamper-proof feature, insert the blade of a small screwdriver into the hole on the side of the base and push the plastic lever away from the detector head. This will allow the detector to be rotated counterclockwise for removal. Note: The decorative ring must be removed in order to remove the head when using the tamper-proof feature. The tamper-proof feature may be defeated permanently by breaking the plastic lever off the base. Note: The number of two-wire smoke detectors which can be accommodated per zone varies with different control panels. Consult the control panel instruction manual to determine the capacity. Refer to NFPA 72, Chapter 5-3, “Smoke Sensing Fire Detectors” for spacing, location of detectors and other guidelines. Testing Detectors may be tested in the following ways:
  • Place a test magnet against the cover opposite the test module socket. (See illustration). The detector should go into alarm within 5 seconds.
  • Field metering of detector sensitivity may be performed with the aid of a voltmeter and Test Kit MOD 400R. For the complete procedure, refer to the Installation and Maintenance Instructions furnished with each detector. Maintenance Cleaning programs should be adapted to the individual environment. We recommend at least, an annual cleaning of the unit. The detector screen and cover assembly can be removed, revealing the sensing chamber. A vacuum cleaner can be used to remove dust from the screen, cover and sensing chamber. For the complete procedure, refer to the Installation and Maintenance Instructions fur- nished with each detector. GAMEWELL-FCI
