The G.R.I. 290 Series Door Monitors have been designed to monitor access points leading to or from a controlled area, thus preventing
doors from being accidentally left open or purposely propped open for extended periods of time. The 290 Series Door Monitors are fully
self-contained alarm systems that can be mounted locally or remotely to monitor an access door using a simple closed loop magnetic
reed switch. A perfect solution for that single exit door at the end of a long hallway or that isolated doorway everyone seems to forget
about.
The G.R.I. 290-1 and 290-2 must be operated with a 12 volt externally supplied DC power source. If installed, the battery will
perform a backup function should the external source fail. Both power sources have been designed to maintain a minimum sound
pressure level of 85 dB.
NOTE: The unit will function at minimum 5 VDC at a very limited sounder volume. This power level is considered total battery failure.
CAUTION: To prevent a memory failure or circuit damage, external power source not to exceed 15 VDC.
