The new GRI DOOR ALERT/POOL ALARM was designed as an aid for prevention of an unattended access to a pool/spa area by a small child. Monitoring all doors or windows with OPEN LOOP magnetic reed switches, the DOOR ALERT/POOL ALARM will sound an alarm should anyone too small to manage the adult pass thru feature attempt access to the pool/spa area. For maximum protection all moveable openings should be protected in such a manner by the GRI DOOR ALERT/POOL ALARM.The 189-1, 189-2, 189-3 and 189-4 must be operated with a 12 volt externally supplied DC power source. An onboard 9-volt battery may be installed, in which case the battery will perform a back-up function should the externally supplied source fail for any reason. Both power sources have been designed to maintain a minimum sound pressure level of 85db at 10’. Should the battery voltage drop below 7 volts, a low battery mode will be initiated and the unit will sound 2 beeps approximately every 3 seconds for one to two weeks prior to total battery failure. Battery must be replaced at this time, and the cause of power failure determined and restored.It is suggested that some type of surge protection, such as the GRI CS-1 Current Sensor, be used between the power supply and all GRI Pool Alarms using external power.
