GENERAL INFORMATION
TAMPER SUPERVISION
The ADEMCO 5821 Temperature Sensor & Flood Detector The 5821 tamper supervision feature (Loop 4) causes a is a wireless transmitter used with Honeywell's ADEMCO trouble signal to be sent to the control if the unit's cover is alarm systems that support 5800 series devices. The 5821 removed from the base or if an external probe is used and can be configured to operate as a stand-alone temperature the wire is cut (open) or the probe is shorted. The tamper sensor and/or as either a Remote Temperature Sensor or
switch is also used to program the unit's serial number and Flood Detector. The 5821 in combination with the loop assignments to the control panel. ADEMCO T280R temperature probe is ideal for monitoring SETTING THE OPERATING MODE
refrigerators and freezers in restaurants, kitchens and warehouses where food storage is a concern. The 5821 in Table 1 provides a list of the various operating modes of the combination with the ADEMCO 470PB probe can be used to 5821 with the respective Loop and DIP Switch settings for sense floods in basements and other areas where there is a each. Note that Cold Temp Sensing can be used in possibility of flooding. The 5821 will send an alarm, via its combination with any of the other operating modes. To use RF transmitter, to the control when the preset temperature the transmitter to monitor two different conditions, you limit is exceeded or when a flood is detected. Temperature must program each loop used on the 5821 as its own zone, monitoring and flood detection is dependent on the and you must set the DIP Switches as shown for the operating mode selected. Refer to Table 1 for applicable combination functions in Table 1. operating modes. PROGRAMMING THE UNIT
Room temperature is monitored at the device using the Once you have selected an operating mode and have set the 5821's internal sensor.

A 3-volt lithium battery powers the 5821. If the battery voltage gets too low, the 5821 sends a low battery signal to 4.

Refer to the Testing blade of a small screwdriver into the pry-off slot at one end of the unit (see Figure 1 for location), and slightly twisting the blade until the cover disengages. 2. Install a 3-volt lithium battery as shown in Figure 1. MOUNTING THE DETECTOR
To mount the detector, proceed as follows: You can mount the 5821 on a wall or ceiling within the 1. Remove the transmitter's top cover by inserting the flat protection area. The following notes apply: blade of a small screwdriver into the 'pry-off' slot at one • The 5821 may be installed in any direction. end of the unit (see Fig. 1 for location), and slightly twisting the blade until the cover disengages.

Avoid mounting 4. Install the mounting plate, with its two case- holding the detector near heat generating devices (e.g. ovens, posts pointing up (in this example), in the location heat vents, furnaces, boilers) or to a metal cabinet or selected. Use the flat-head screws supplied. 5. For surface wiring entry, two thin "breakout" areas are Wireless Transmission Path Test

This detector should be used for property protection. Reliance should not be placed on this detector for life safety. When life safety is involved, smoke detectors MUST also be used. The flood probe must not be painted. TESTING THE DETECTOR
The test procedure should be performed to determine a good RF transmission path and again after installation is completed. To test, Activate the control panel's test mode. Activate the detector by removing and replacing the cover. The system's keypads should beep and each zone the 5821 is programmed for will be Exit the control's test mode (User Code + OFF). MAINTAINING PROPER OPERATION
To maintain the detector in proper working condition, it is important that you observe the following: Replace the battery when the system indicates that the 5821 reported a low battery condition. Units should never be relocated without the advice or assistance of the alarm service company. Figure 1
