GENERAL DESCRIPTIONDETECT-A-FIRE units are the “heart”of many Fire Protection Systems. These highly reliable devices have been a standard of the industry for over 45 years. Many thousands of these units are now in use controlling the release of extinguishants such as clean agents, CO2, water, or dry chemicals. In some systems the device is used as an ALARM device, to sense ove-rheat or fire, and alert personnel. In other systems, it is used as a RELEASE device, to sense fire and actuate fire attack systems. DETECT-A-FIRE units have met with wide acceptance because they are designed with RATE COMPENSATION. This provides a unique advantage over both fixed temperature and rate-of-rise types of detectors because only the DETECT-A-FIRE unit accurately senses the surrounding air temperature regar-dless of the fire growth rate. At precisely the predetermined danger point, the system is activated. Fixed temperature de-tectors must be completely heated to alarm temperature and therefore a disastrous lag in time may occur with a fast rate fire. Rate-of-rise devices, on the other hand, are triggered by the rate of increase in ambient temperature and are subject to false alarms caused by harmless, transient thermal gradients such as the rush of warm air from process ovens. The secret of the unit’s sensitivlty is in the design (figure 1). The outer shell is made of a rapidly expanding alloy which closely follows changes in surrounding air temperature. The inner struts are made of a lower expanding alloy. Designed to resist thermal energy absorption and sealed inside the shell, the struts fol-

This chart shows three categories of fire detection devices and their relative response levels for reaction to three different rate - of - rise conditions. Statistics indicate that 97% of all fires fall within these categories.

low temperature changes more slowly. A slow rate fire (fIgure 2) will heat the shell and struts together. At the “set point”, the unit will trigger, actuating the alarm or releasing the extinguishant. A transient rush of warm air up to 40F°/min. may expand the shell, but not enough to trigger the unit. By ignoring transient warm air excursions, the DETECT-A-FIRE unit virtually eliminates false alarms prevalent with rate - of - rise devices. If a last rate fire (figure 3) starts, the shell will expand rapidly. The struts will close, actuating the alarm or releasing the agent. The faster the fire rate of growth, the sooner the DETECT-A-FIRE unit will react.

HORIZONTAL DETECT-A-FIRE UNITS Horizontal detectors are designed for locations where appea-rance is a factor. The attractive, functional design lends physical protection of the unit while making it suitable for commerciaI, industriaI, mercantile and public buildings, institutions and ships in non-hazardous locations (those classified as “ordinary” under the National Electric Code). Flush mounted units are designed to fit standard 4” octagonal electrical boxes and surface mounting units are designed to mount directly on ceilings or on 4” electri-cal junction boxes. Canadian Electrical Code requires mounting only to an electrical junction box.

VERTICAL DETECT-A-FIRE UNITS Vertical detectors are designed for use in both “ordinary” or “hazardous” locations. For “ordinary” use, they may be moun-ted to any approved junction box with 7/8” diameter opening by using 1/2- 14 NPT mounting nuts. The device may be wired in or out of conduit, depending on local preference and codes. Four leadwires are provided on normally open vertical units (that close on temperature rise), per UL requirement, to facilitate su-pervision of system wiring. Instruments are Underwriters Labora-tory and Underwriters Laboratory of Canada listed and Factory MutuaI approved for hazardous locations, when mounted in a suitable fitting.
