Program the Pendant

Program the pendant as an Emergency (EM) Zone type in Zone Information during panel programming. At the Serial Number: option, enter the eight-digit serial number on the back of the pendant. Refer to the panel programming guide as necessary. To extend battery life, Supervision Time programming should be set to 0.

LED Status Operation Programming

When the button is pressed, the 1148 Status LED operates according to the LED OPERATION NO YES option in ZONE INFORMATION.

YES The Status LED blinks once when the button is pressed and once every second for five minutes to confirm a message was sent.

NO The Status LED blinks once when the button is pressed to confirm a message was sent.

LED Survey

The 1148 Personal Pendant provides a Survey LED capability to allow one person to confirm communication with the wireless receiver or panel. Press the button to send data to the panel and determine if communication is confirmed or faulty.

Confirmed: Proper communication between the transmitter and receiver is verified when, for each press of the button, the LED blinks immediately on and immediately off. Repeat this test to confirm five separate consecutive LED blinks.

Faulty: When the LED remains on for approximately eight seconds to indicate that communication is not established. Communication is also faulty when the LED flashes multiple times in quick succession. Relocate the receiver until the LED immediately turns off indicating the transmitter and receiver are communicating properly.

Test the Pendant

As with any non-stationary wireless device, the 1148 pendant should be tested at least every 30 days. The 1148 is for use in applications where it stays within the range of the wireless receiver. Should the pendant be taken out of the range of the receiver, press the pendant button to test it once it is within range.
