The Honeywell 5817XT is a 3 zone wireless transmitter supported by any 5800 series RF receiver. It is labeled as "universal" not for its wireless function back to the alarm panel but for its ability to support just about any wired contact. Inside the tamper cover of the 5817XT there are three pairs of terminal blocks to land wired contact loops. There are 3 programmable loops: The primary loop (loop 1) can be configured as normally open (NO) or normally closed (NC) while the auxiliary loops (loops 2 and 3) only support NC devices. Since these are wired loops they will support several contacts in a series loop. This can helpful when trying lower the total number of zones on your wireless alarm system. In other words, you can wire up all the windows on the first floor in a single circuit and wire it to a single zone on the 5817XT!
The 5817XT is not unique in its ability to transmit wired contact loops wirelessly. In fact, devices like the 5816 and 5800C2W are also capable of this very same function. However what makes this product special is the function of the primary loop. Unlike these other products, loop 1 supports NO or NC devices. This is particularly useful for wired life safety devices like smoke and heat detectors. The 5817XT lays out a diagram with 4 different settings for the primary loop. These settings are configured by toggling the dip switches located inside the device. When enrolling the 5817XT with the receiver be sure to have all the dips off. The transmitter will reset when dips are adjusted. It may take up to one minute for the device to fully reset.
Dip 1: Single or repeating transmissions. Normal contacts for doors and window send a single signal upon faulting of the zone. However life safety devices require "high-priority" settings which involve repeating the transmission of the fault signal multiple times (every 4 seconds to be exact).
Dip 2: Normally open or closed circuit. As mentioned earlier the aux loops support NC devices which are the standard for the large majority of burglary devices. NO devices may be used on something like an overhead garage door contact but generally used for fire protection. In other words, you can disable this dip and setup three NC wired loop zones or enable this loop and connect a NO device(s). There is no end of line resistor (EOLR) supervision offered on the 5817XT. Just simple normally open or normally closed.
Dip 3: Fast or normal response times. Response time is the time in which it takes for a fault to be sensed and reported back to the transmitter. The aux loops use the standard or "normal" response time of 320mSec. If there is an application that requires quicker response time you can disable this switch and bring this time down to 5mSec. This is commonly used for life safety devices.
Dip 4: Three minute transmission inhibit which Honeywell coined as "Transmission Lockout." This technology is also used on the 5800PIR-RES for battery saving purposes. If switch 4 is on, all three loops will ignore any faults for three minutes. This is basically a battery saving feature and is generally designed for commercial entry doors with heavy traffic. If the system is disarmed and the primary loop is faulted all three loops will be locked out for 3 minutes after the restore of the primary loop. For obvious reasons, this setting must be disabled if there are life safety devices involved.
Keep in mind, life safety devices require power. Typically there will be an auxiliary power supply and a relay (provided separately). In most cases, the relay will be hardwired to a trigger output on the alarm panel. This way the relay can receive a signal from the panel upon the restore of the primary loop. Then the relay will reset power on the aux power supply.
