Operation & Test
1). Connect 12V power supply to GSM-DL2.
2). Record the voice message under disarmed state.
3). Program tel. numbers and SMS message on the mobile phone independently.
4). Make sure the GSM-DL2 is disarmed, and the power of the mobile phone is turned ON. Then
connect the mobile phone to the GSM-DL2 .
5). Arm the GSM-DL2, wait several seconds till the Green LED turns into quick flashing (this
delay time depends on connected mobile phone, could be 5~15 seconds), then apply +12V to
ZH (or apply 0V to ZL) for 2 seconds minimum, the GSM-DL2 will start to dial telephone
numbers.
Note: 1. If the battery of the mobile phone is too low, please fully charge it before
connecting. Otherwise, you have to wait several hours till it’s charged by the
GSM-DL2, before you can test the GSM-DL2.
2. Whenever the GSM-DL2 is turned ON (from OFF), or Armed (from Disarmed
state), it would take about 10~20 seconds for the GSM-DL2 to fetch the data
from the mobile phone, so the mobile phone should be turned on and connected
to the GSM-DL2, before the GSM-DL2 is turned ON or armed; otherwise, the
GSM-DL2 will be in a waiting loop. The waiting loop can be terminated by
Disarming the GSM-DL2, or it would end automatically after 30~40 seconds.
