Use any 4-wire smoke detector which is rated for 10-14VDC operation and which
has alarm reset time not exceeding 6 seconds. Some compatible 4-wire smoke
detectors are listed below.
Photoelectric, direct wire
Photoelectric w/heat sensor, direct wire
Ionisation, direct wire
Zone 7 may be programmed to serve as a keyswitch input. If using a keyswitch
on zone 7, it can be assigned to only one partition. To enable the keyswitch, do
the following:
1. Enter the partition number to which the keyswitch is assigned in programme
field *15.
2. Zone 7 is automatically assigned a response type 10 (Interior w/Delay).
3. Wire the keyswitch to zone 7. Connect the EOL resistor across the zone. If
using keyswitch LEDs, wire as shown in the VOLTAGE TRIGGERS section.
Use zone 8 for connection of compatible 2-wire latching-type glass break
detectors. Wire as follows (also see diagram below):
1. Connect all detectors in parallel across zone 8 (terminals 21 and 22).
Remove the 2000 ohm EOL resistor if connected across the selected zone terminals.
You must connect the EOL resistor across the loop wires at the last detector.

After an alarm, the first code + OFF turns off the siren and disarms the system;
the second code + OFF clears the memory of alarm and resets the glassbreak
detector.
Use detectors that meet the following ratings:
Standby Voltage:
Standby Resistance:
Alarm Resistance:
Alarm Current:
Reset Time:
The IEI 735L series detectors and FBII SH8 shock sensors have been
tested and found to be compatible with these ratings. You can use up to fifty IEI
735L detectors connected in parallel. You can use up to four SH8 sensors
connected in series.
