Wireless Zone Expansion

The 5881ENHC RF Receiver is Listed for Commercial Fire and Commercial Burglary applications. The 5883H is

Listed for Commercial Fire applications only. All other RF receivers are not UL listed for Commercial applications.

The following table lists the receivers that may be used and the number of zones they support.

5800 Series Receivers

Receiver Zones

5881ENHC up to 250 (use in commercial fire or

burglary applications)

5883H up to 250 (use in commercial fire

applications)

RF System Operation and Supervision

The 5800 RF system operation has the following characteristics:

• The receiver responds to a frequency of 345MHz.

• The receiver has a nominal range of 200 feet.

• Supervised transmitters send a supervisory signal every 70-90 minutes.

• Zones 988 and 990 are used to supervise the RF reception of receivers 2 and 1, respectively. The reception is

supervised for the following two conditions:

1. The receiver goes “deaf” (doesn’t hear from any transmitter) within a programmed interval of time (defined by

program field 1*30).

2. Proper RF reception is impeded (i.e., jamming or other RF interference). The control checks for this condition

every 20 seconds.
