APPLICATION:

The GRI DOOR ALERT/POOL ALARM is designed as an aid to detect unsupervised access to a pool/spa area by a small child. Monitoring all doors and windows with magnetic reed switches the DOOR ALERT/POOL ALARM will sound an alarm should anyone too small to manage the adult pass through 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

DESCRIPTION:

The GRI DOOR ALERT/POOL ALARM uses a microprocessor to monitor the CLOSED LOOP magnetic reed switches, shunt/cancel button, battery and power supply voltages, and to provide the timing options. The re- cessed versions are designed to fit inside a single gang utility box, while the surface mount versions may easily be mounted to the wall of any structure.

The 289N-1 and 289N-2 versions offer a seven second delay in which an adult may open the protected door, shut it, and then press the shunt/ cancel button without the alarm sounding. The 289N-3 and 289N-4 versions alarm instantly if the protected door is open before the shunt/cancel button is pressed.

All versions must be operated with a 12 volt externally supplied DC power source. An onboard 9 volt battery can be used, in which case the battery will perform a backup function should the externally supplied source fail for any reason. The GRI DOOR ALERT/POOL ALARM is designed to maintain a minimum sound pressure level.
