How Do I Install A Honeywell 5816 Sensor

Before installing the 5816 transmitter,conduct a Go/No Go test to verify signal strength.

Once the signal strength has been verified, use the finger latch to remove the 5816’s cover.

Separate the mounting plate by releasing the locking tab while sliding the plate downward along the back case.

If a wired contact loop is being used, feed the wires through the entry hole at one corner of the mounting plate.

With the holding posts pointing up mount the plate using the included flat head screws. The 5816 may be installed in any direction, as long as the relationship of the sensor, mounting plate and magnet is maintained. The magnet needs to be installed to the right of the sensor.

The 5816 has two unique zones; the first is for a wired closed circuit contact loop and the second for its built-in reed switch used in conjunction with a magnet. Either or both zones may be used. For UL installations, a contact may not be more than 3 feet from the transmitter.

With the battery still not inserted, connect the contact loop if being used to the unit’s loop terminals. The contact loop must use closed circuit devices. The loop response time is a nominal 100mSec. If the unit’s reed switch is to be used,mount the magnet adjacent to the alignment marks on the case and the mounting plate’s alignment strip at maximum ½ inch separation. If the contact loop is not to be used, no connection is needed across its terminals.

Insert the battery (CR123A)observing the correct polarity.

Attach the back of the to the mounting plate by sliding the keyhole slots down onto the mounting plate’s case holding posts. The locking tab will click as the back locks in place.

The 5816 transmitter has its own unique 7 digit serial number which is assigned during manufacture. The 5816 must be “enrolled” in the control panel to be active.

Yes, the magnet should go on the side with 2 raised marks, to show you where the reed switch is located on the inside of the 5816. It doesn't matter which side is up, so long as the magnet is in the right place. Also, be sure the loop number is programmed correctly for the zone. The magnet and reed switch should be programmed as loop 2.
I'm having trouble with one of my 5816s. It keeps reporting fault even after a fresh battery. I have about 6 others and they are all fine. Does it matter which side the magnet is on or which direction is "up"?
Just to be clear, when you get home, you should put the cover back securely in place, then I would open and close the sensor (take the magnet away, and put it back) then enter your code + off or Disarm sequence. You may have to Disarm twice to clear it.
I think I have tried it both ways but I know the last few attempts are with the cover off. I will give it another try when I get home. I didn't think about that....
Do you have the cover off the sensor? If so, it's normal behavior that it will start beeping (with the tamper trouble error) as soon as you "fault" the sensor.
I have a honeywell vista 20p with a 6162rf and tuxedo controls. I have 2 5818s and 3 5800pirs that are all working fine. I went to add a 5816 today but when I trip the sensor I get an error/trouble on the panels and a continuous beep. It is programmed as zone 19, entry type 1, partition 1, report code 01, and I am able to confirm the sensor in the setup process. I am also using loop 2 with the magnet which is almost touching. I was attempting to install this on a patio door but even took it off and tested withing a couple feet of the rf panel with the same result. I am guessing there is a problem with the 5816 sensor.
