Honeywell 5818MNL vs 5815

The Honeywell 5818MNL is a wireless, recessed, 1 zone door transmitter. The 5818MNL is a self contained transmitter and reed sensor and must be programmed as loop 1. Being that the 5818MNL is a recessed transmitter, the device will require a 3/4" diameter hole in the edge of the frame, at least 3" deep. The magnet will need a 3/8" diameter hole in the edge of the door at least 1/2" deep.

The Honeywell 5815 is a wireless, surface mount, 2 zone door window transmitter. Loop 1 is for wired closed circuit terminals, and Loop 2 is the 2 built in reed switches which are in parallel with each other. One is located on one end and the other is located on the side. Only one can be used but both loops can be used at the same time. The 5815 can be mounted with or without the mounting plate. It is recommended that the mounting plate be used, for ease in removing the transmitter for servicing should it become necessary.

Both the 5818MNL and 5815 have an RF transmitting range of 200 feet. Mounting either device to any metal structure is not recommended and should be avoided as this may decrease and interfere with transmitting range and operate in temperatures that range from 32 degrees F - 120 degrees F.

The 5818MNL dimensions are ¾” Diameter and 3” Long and the Magnet is ⅜” Diameter and ½” Long which makes it half the size of standard transmitters.

The 5815 dimensions are 1 ½ "W x 3"H x 7/8"D which makes this transmitter part of the 5800 “small” series.

Both the 5818MNL and 5815 are supervised and have RF supervision and low battery detection. The 5815 also includes a built in cover tamper which is activated when the cover is removed.

The 5818MNL operates on one 1.5VDC, AAA Lithium and has a battery life of up to 10 years.

The 5815 operates on one 3V Lithium battery and has a battery life of 3-5 years.
