2 / 4 P/N 10-4213-501-ZX01-02 • ISS 12MAR18
Configuration: 868 MHz systems
Dual detector mode
To operate the device in dual detector mode, DIP switch 7
(SW1) must be set to OFF (see Figure 1), enabling the
detector to make the alarm decision based on both the
detector’s sensor readings.
Multisensor mode
When not set to dual detector mode, the detector can use one
of two algorithms to control sensitivity levels.
Algorithm 1: With an increase in heat, the optical sensitivity is
increased (more sensitive). Available options are shown in
Table 3.
Algorithm 2: If an optical prealarm level is reached without an
increase in heat, the optical sensitivity is decreased (less
sensitive). Available options are shown in Table 4.
Single detector mode
The detector can also be operated in a single sensor mode.
When operated in this mode, the detector can be configured to
operate as a heat detector or as an optical detector. See
Table 5.
Configuration: Legacy systems
Dual detector mode
To operate the device in dual detector mode, it must be used
with the ZR401-MS-2 Multisensor Radio Base and DIP
switch 7 (SW1) must be set to OFF (see Figure 1), enabling
the detector to make the alarm decision based on both the
detector’s sensor readings.
Multisensor mode
To operate the device in multisensor mode, it must be used
with the ZR401-MS-2 Multisensor Radio Base. In this case, the
detector can use one of two algorithms to control sensitivity
levels.
Algorithm 1: With an increase in heat, the optical sensitivity is
increased (more sensitive). Available options are shown in
Table 3.
Algorithm 2: If an optical prealarm level is reached without an
increase in heat, the optical sensitivity is decreased (less
sensitive). Available options are shown in Table 4.
Single detector mode
The detector can be used in single sensor mode with specific
legacy mounting bases. When operated in this mode, the
detector can be used as a suitable replacement for the ZR420
heat or ZR430 optical detectors.
ZR401-MS-2, ZR401-MS-2-SWE:When used with these
bases, see Table 5.
ZR401-1, ZR401-1-SWE: When used with these bases, see
Table 6.
