4-6 5300 ES Series Mobile Radio Operating Manual March 2008
Radio Wide Features
4.8 Horn Alert
The horn alert feature sounds an external alert such as the vehicle horn when certain calls
are received. It is available if a Horn option switch is programmed and the proper
connection has been made to the external alert. The horn alert output is pin 4 of the
accessory cable, and an external driver circuit of some type is usually required. Refer to
the Installation section of the 5300 ES Service Manual for more information on how to
install this feature.
Additional information on the horn alert feature follows:
• It activates when receiving any Unit call in the P25 conventional mode and any Private/
Unit and Call Alert (paging) call in the SMARTNET/SmartZone and P25 Trunked
modes. It does not sound when receiving standard Group or telephone calls, and is not
programmable on a per call basis.
• It must be manually enabled and disabled by the Horn option switch. It is not controlled
by the vehicle ignition switch. When it is enabled, “HORN ON” is briefly displayed,
and when it is disabled, “HORN OFF” is briefly displayed. It defaults to the OFF mode
whenever power is turned on.
• If a power turn-off delay is programmed as just described, it is functional during that
delay.
• When activated, it can be programmed to sound for three 1-second beeps or
continuously for 2-90 seconds. It then turns OFF until another Unit call is received.
4.9 Microphone Off-Hook Detect
The microphone hanger can be connected to chassis ground and the radio programmed to
detect an off-hook condition (Hangup Box Monitor selected). The following operation
then occurs when the microphone is taken off-hook:
Conventional Channel Selected - Scanning temporarily halts (if applicable) and the
Monitor Mode described in Section 5.2 is enabled. However, the receiver unsquelches
only if a carrier is detected.
SMARTNET/SmartZone/P25 Trunked Channel Selected - Scanning temporarily
halts if applicable.
If the off-hook condition is not detected (Hangup Box Monitor not selected), the
microphone hook state has no affect on radio operation.
