Description

Edwards 284C Heat Detector and all models if the temperature of the center disk rises to the detector is rate temperature [135º F (57.2º C) or 197ºF (91.7º)] contacts in the detector close. We actuated by the fix temperature element. The detector is nonrestorable and replace it . They need to replacement indicate when the center disk has fallen free.

Edwards 284C Heat Detector must be installed in accordance with CAN/ULC-S524-M86 and the latest issue of the Canadian Electric Code, section 32.

The detector must be mount either to an electric box or surface mounted using the supplied metal.  Also optional plastic mounting plate. Install the plate using one of the following applicable mountain procedure.

The requirements for maintenance and testing of the heat detector 284C is cover in CAN/ULC-S524-M86 standards for testing, inspection. And maintenance  of Existing Fire Alarm System. The standard requires that:

One- third of the automatic alarm initiating devices be inspect. Also test it for operability in such a way the each device are test within three year. Heat Detectors found to be demand or paint are no to be note and replacement recommend.

Note: using an open flame to test this detector invalidates guaranty.

Nonrestorable heat detectors are to test on a lot sampling basis when warrant by age or evidence. Also for deterioration from environmental conditions. The continuity of the initiating circuit to the heat detector locations is test by the application of a shunt resistance of a value equal to provide the heat detector during information. And  check for the correct response at the control unit.
