The 1821 is a Pulse Count Module that will fit into the wiring compartment of a
Securilite 1804 or 1811 PIR Sensor. It will provide additional security against false
alarms and / or provide an interface with your intruder alarm panel, CCTV equip-
ment, auto-dialler, pager etc. while still working with the Securilite lighting control-
lers.
FEATURES
• 12V dC operating voltage.
• Compatible with Securilite 1804 & 1811 or any PIR with a -ve signal output.
• Selectable pulse count 1, 2, 3 or 4.
• Adjustable Time Frame of 5, 10, 20 or 30 sec.
• Adjustable relay alarm time (2 sec. to 5 mins.)
• Normally open and normally closed relay output.
• Lighting controller output (-ve signal in alarm)
• Relay output will go into alarm on removal of power.
• Relay & transistor will go into alarm if the PIR input is disconnected.
Please note : when handling the pulse count module, care should be
taken to hold the board by the edges therefore avoiding touching the
electronic components or tracks.
1. Use the guidelines provided with the PIR sensor to choose the best
location for the sensor.
2. Remove the lid from the PIR sensor.
3. Remove the five wires from the connector and then connect them to
the Four way connector on the pulse count module as shown on the
next page.
