2 Remote Siren/Strobe Unit
2.1 Description
The IntegrAlarm model IA-SRN1 remote siren / strobe unit consists of an RF transceiver, a
micro-controller with non-volatile memory, siren generator and amplifier, a piezo element
and horn, a high voltage power supply and a discharge tube, a power supply with back-up
batteries, and a wall mounted mains isolation transformer, 115 to 12 VAC.
The remote siren / strobe unit is composed of the following principal parts:
• Top cover in two sections: opaque white and transparent red.
• Siren / strobe unit base with siren piezo element and horn, battery holder
for 6 NiCad rechargeable batteries and two tamper switch actuators.
• RF / controller, siren and strobe circuitry PCB with strobe discharge tube.
• 6 AA NiCad rechargeable batteries (7.2 V).
• Wall mounted mains isolation transformer, 115 to 12 VAC.
An exploded view of the IA-SRN1 remote siren / strobe unit is shown in Figure 1 below.
The IA-SRN1 remote siren receiver continuously monitors the control panel
synchronization and command packets. Upon receiving a command packet that contains
the correct system and peripheral ID, the IA-SRN1 remote siren controller will
acknowledge the receive packet and activate the siren in the requested pattern with or
without the strobe.
In case of tamper, the IA-SRN1 sends an alarm packet to the control panel that in turn
activates the siren if the system is armed.
Automatic transmission / reception periodic test, programmable from the control panel,
periodically verifies the IA-SRN1 remote siren operation.
